- Merge material changes for COGLES1MaterialRenderer_LIGHTMAP and COpenGLMaterialRenderer_TRANSPARENT_ALPHA_CHANNEL which had been done in OGL in trunk (r2740) to ensure materials look the same on all platforms.
- COSOperator::getSystemMemory now returns some value on OSX (thought same for total and available).
Thanks @sfan5 for patch https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819 and https://github.com/minetest/irrlicht/commit/e469c54f76f6d24f92389b4e8a27b9cce7152888
- Fix CVertexBuffer::setType switching types for non-empty arrays. Before we had some bad casts which could result in random initializing of some vertex data.
- IVertexBuffer interface changes: pointer() now returns void*. Adding a const version of getData(). Some set functions have now overload for all vertex types.
- S3DVertex now always initializes color to 0xffffff. That was previously the only uninitialized variable in there. Also both derived classes have now a constructor taking a const S3DVertex&.
- Fix deserialization in CGUITable. Use now getAttributeAsStringW instead of getAttributeAsString.
Thanks @chronologicaldot for report and patch: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=7&t=52821
- IIndexBuffer interface changes: Adding a const version of getData(). Some set functions now copy by value instead of per reference, which shouldn't be slower for this and is safer to use.
- Fix CIndexBuffer::setType going from 16 to 32 bit. This had some casts which simply could mess up the results.
- Fix OSX nor resizing properly. Thanks @torleif, Jordach and sfan5 for patch and report: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819
- X meshloader fixes bug with uninitialized normals. Thanks @sfan5 for patch: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819
- stl meshloader now faster, especially with text format
- CMemoryReadFile::seek CMemoryWriteFile::seek and no longer allowed to go _before_ start.
Thanks @sfan5 for patch: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819
- stl meshloader can now load 32 bit buffers.
Thanks @Foaly for the patch: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=9&t=51441
- Add IMeshBufffer::clone function to create buffer copies. CMeshManipulator::createMeshCopy uses that now and works now with all types of meshbuffers.
- Add IMeshBuffer::getType to allow finding out which class type a meshbuffer has (similar to ISceneNode::getType).
- Add IGUIImage::flip to flip/mirror images
- IBillboardSceneNode got functions to access meshbuffers. So uv-coordinates can now be modified directly (previously only possible via texture matrix).
- vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.
Costs some speed, but fixes floating point troubles caused by this optimization (like x/x no longer being 1.0).
- Bugfix: XML reader dropped last character in strings if there was a special character replacement for the second-last character.
- Avoid allocating more than 16k on stack in OCT loader. Also avoid potential heap overwrites in there.
- Add equals and set_data functions to core::array for easier working with blocks of data.
- SIrrlichtCreationParameters::IgnoreInput set to false works again on X11.
Thanks @ Victor Gaydov for report + patch + very good test cases! (bug #401)
This had been broken since Irrlicht 1.6
- Add steer parameter to CSceneNodeAnimatorFollowSpline which allows rotating node toward direction of movement.
Thanks @ Bate for the patch (patch #175)
- Add a workaround for XWarpPointer bug that causes mouse to jump when users have set a Coordinate Transformation Matrix for their mouse on X11.
This was mentioned in bug #450 by vikaig.
The fix needs compiling with _IRR_LINUX_X11_XINPUT2_ enabled (so far disabled by default)
- Add IGeometryCreator::createTorusMesh to create donuts.
- Don't try loading broken image files twice with same loader anymore.
- Make CImageLoaderJPG thread safe. Thanks @ Edoardo Lolletti for report and patch (patch #324)
- Add ETCF_SUPPORT_VERTEXT_TEXTURE flag which can be used to enable vertex texture sampling support in Direct3D 9.
Note that this was enabled for a long time in 1.9 svn, but is now disabled by default.
- CGUIListBox now serializes the state of "Selected". Feature wish by chronologicaldot (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=2&t=52719)
- Bugfix: Changing focus with tab-keys now also work when elements are inside a modal screen.
- COBJMeshFileLoader using a bit more exact color conversion for 0-1 to 0-255 range (same now as SColorf::toSColor uses).
- Speedup for COBJMeshWriter
- Add blinkMode parameter to IGUIEnvironment::addModalScreen, so blinking can be suppressed
- Speedup: Avoid string copy in CXMLReaderImpl::getAttributeByName
- Fix bug in rect::clipAgainst that had caused rects completely outside to the left-top of the rect to be clipped against ending up with both corners outside.
It still worked for UI in most cases as the resulting rectangle still had an area of 0.
- Add optional multitouch support to X11 (but disabled in IrrCompileConfig by default). Thanks @TheBrokenRail for a patch proposal based on example code from esjeon (patch #322).
- Slightly changed close window handling on X11 (optimized and avoids problems on some shells). Thanks @TheBrokenRail for a patch (was part of patch #322).
- Add getActiveColor functions to IGUIStaticText and IGUIButton (get currently used color).
- Add IGUIEnvironment::addToDeletionQueue to allow save removal of gui elements while iterating over them (like the same named function in ISceneManager).
- IGUIEnvironment::drawAll has now a parameter to allow disabling automatic resize to screensize. Makes it easier to use partial screens with full alignment support.
- Fix bug that AnimatedMeshSceneNode ignored ReadOnlyMaterials flag when checking materials for transparent render passes.
- Unify checks if materials should use transparent render pass with new IVideoDriver::needsTransparentRenderPass function.
- Material.ZWriteEnable is now of type E_ZWRITE instead of bool. This allows now setting materials to always "on" independent of material type and transparency.
This breaks compiling. To have old values replace false with EZW_OFF and true with EWZ_AUTO.
- Materials EMT_REFLECTION_2_LAYER and EMT_TRANSPARENT_REFLECTION_2_LAYER on OpenGL are now same as in D3D9. Before GL used a sphere-map for those instead of reflection.
- Bugfix: CGUIToolBar automatic placement no longer outside of screen when there are modals screens when creating it.
Or when there are other window elements going over full window-size.
Thanks to Stephen Lynx for the bugreport and to S<>rgio Augusto Vianna for writing a test case with a bug example.
Changes: a) Never move the toolbar below it's parents lower border. b) No longer check all element-types, but only try to be below other toolbars or menues.
- Add a normalType parameter to IGeometryCreator::createCylinderMesh
- Add a normalsUpdate parameter to IMeshManipulator::transform to allow updating the normals with the inverse-transpose of the transformation matrix.
- Bugfix: quaternion::slerp now uses lerpN instead of lerp to keep result normalized.
- Add function quaternion::lerpN which is like lerp but normalizes the result.
- Add function ISceneManager::createShadowVolumeSceneNode to allow custom ISceneNode's to use shadows.
- CGUITabControl serialization changed to allow using custom tabs (before only CGUITab could be serialized).
There was a lot of rewriting involved, including some minor interface changes (IGUITab* can now be added directly for example).
See http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52344 for a thread about this.
Thanks @chronologicaldot for bringing this up, writing a patch proposal and even writing test.
- CGUITabControl no longer eats EMIE_LMOUSE_PRESSED_DOWN (doesn't seem to need it, was just done for a planned feature which is not implemented yet).
- Removing a tab in CGUITabControl will now also remove the tab-element. Fixes problems like tabs still being around & visible when you removed the active tab.
- Fix ms3d loader to work on big endian systems which need floats to be aligned in memory. Thanks @ kas1e, Corto and Salas for the patch (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52538).
- Bugfix: COBJMeshFileLoder no longer overwrites transparency value with 1.0 when it's set before the diffuse color value in the mtl file. Thanks @Boshen for bugreport (#445).
- Drivers can now try to create textures from images in more exotic color formats (like floating point formats). It depends on the driver how much that works (so far mainly OpenGL can handle it somewhat).
- Fix OpenGL to no longer switch colors red and blue in 24-bit RGB format. But warnings added to documentation to avoid 24-bit textures as they are generally just trouble.
- No longer try to convert ECF_R5G6B5 to ECF_A1R5G5B5 on OpenGL (just made texture-loading seem to fail).
- Add parameter SIrrlichtCreationParameters.WindowResizable. Mainly to work around troubles with SDL+OpenGL on some platforms where resizing later can be tricky/impossible.
- Bugfix: CMatrix4::transformPlane was calculating the wrong plane-normal before.
- SViewFrustum::recalculateBoundingBox no longer includes camera position in the bounding-box. Only using frustum corners now. Thx @DevSH for bugreport & patch.
- Camera uses now OGL projection matrices with OpenGL driver. Fixes wrong near-plane values with OpenGL (showed too much before).
- Add a flag to most CMatrix4::buildProjectionMatrix functions to allow creating OpenGL projection matrices (target range of -w to w instead of 0 to w).
- Bugfix: CCameraSceneNode resets the IsOrthogonal flag to false now when it recalculates a projection matrix.
- SViewFrustum::setFrom and SViewFrustum constructor now use a parameter to allow to set the correct near clipping plane when the projection matrix doesn't use a target depth range of 0 to z, but for example -z to z. So OGL projections matrices can now also use it.
- Remove code to read boundingbox element in Collada reader as it's not in Collada specification.
- _IRR_MATERIAL_MAX_TEXTURES_ now set to 8 by default. So we can use now 8 textures per material without recompiling the engine.
Additionally there's a new global variable irr::video::MATERIAL_MAX_TEXTURES_USED which can be set to lower numbers to avoid most of the costs coming with this for people not needing more textures.
But using more textures via _IRR_MATERIAL_MAX_TEXTURES_ also has become less calculation intensive than it was in the past, so in release builds the difference is hardly noticeable.
- Serialization fixes for materials in irr format (in IVideoDriver::createAttributesFromMaterial/fillMaterialStructureFromAttributes).
- Add serialization for ToolTip to IGUIElement. Thanks @chronologicaldot for patch (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=2&t=52374)
- Try recovering lost device in D3D9 for 3 seconds when device reset fails after resizing Window.
- Add typedefs like value_type and size_type to array, list and map like std containers have. Thanks @SLC for idea (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=1&t=52363)
- CGUIComboBox uses now EGDS_SCROLLBAR_SIZE instead of EGDS_WINDOW_BUTTON_WIDTH for the width of the listbox button to allow changing that without changing window topbar height.
Thanks @LunaRebirth for reporting. (Forum: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=1&t=52297&p=303682#p303682)
- CGUIListbox, CGUITreeView and CGUITable now resize scrollbars when EGDS_SCROLLBAR_SIZE in the skin changes without having to re-create the elements.
This also fixes the problem that drawing looked wrong when this value got changed after the elements were created.
Thanks @LunaRebirth for reporting. (Forum: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=1&t=52297&p=303682#p303682)
- Scrollbar buttons can no longer get larger than half the ScrollBar element to avoid them overlapping.
- Add IVideoDriver::swapMaterialRenderers to allow swapping the renderer used to render a certain material.
- IMeshManipulator functions createMeshWith1TCoords, createMeshWith2TCoords and createMeshWithTangents no longer weld vertices while converting meshes. Use IMeshManipulator::createMeshWelded if you need that welding.
- Add ITerrainSceneNode::setFixedBorderLOD to handle connecting terrain nodes without gaps. Thanks @diho for the bugreport, testcase and a patch proposal (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=51220).
- PLY loader now works with files which use "st" instead of "uv" for texture coordinates (like generated from Blender or Assimp). Thanks @JLouisB for patch (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=52261).
- STL writer does now also write binary files when EMWF_WRITE_BINARY flag is used. Based on patch from JLouisB (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=52261).
(EMWF_WRITE_COMPRESSED also still works for downward compatibility)
- Improved PLY exporter. Thanks for Patch from JLouisB. (Forum: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=52261):
- Support for UV and vertex colors.
- Support for binary PLY files export with the EMWF_WRITE_BINARY flag
- Fix wrong colors on big endian platforms with burnings renders. Thx @kas1e for reporting and @curaga for the patch (#318). Forum bug discussion at http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52177.
- Fix bug #440 where OpenGL driver enabled second texture for single-texture materials when setMaterial was called twice. Thx@ "number Zero" for bugreport and test-case.
- Irrlicht icon now loaded with LR_DEFAULTSIZE to better support larger icon requests. Thx@ luthyr for report and bugfix.
- Cursor on X11 behaves now like on Win32 and doesn't try to clip positions to the window
- IImage::copyToWithAlpha has a new parameter to allow combining alpha value instead of replacing them. This uses new blitters called BLITTER_TEXTURE_COMBINE_ALPHA. Thx @chronologicaldot for providing this patch and @burningreggae for his feedback.
- Reduce log-messages for "loaded texture" and "loaded mesh" from ELL_INFORMATION to ELL_DEBUG.
- Add IGUIButton::setOverrideColor to allow overriding text-color (same function as statictexts and editboxes have).
- Add functions IGUIButton::getClickShiftState and IGUIButton::getClickControlState to get shift/ctrl key-state when a button was clicked. Thanks @StarSonata for patch.
- Add function ISceneManager::clearAllRegisteredNodesForRendering.
- Add support for different geometric primitives to meshbuffers. Thanks @gerdb for patch proposal (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=45999)
- change SEvent::SUserEvent.UserData1 and SEvent::SUserEvent.UserData1 from s32 to size_t to avoid cutting numbers on some 64-bit platforms (SDL and Windows)
- core::string::split now adds delimiter to token before delimiter when keepSeparators is true. That way we never end up with 2 tokens for an original string with a single character.
- Bugfix: SMesh::recalculateBoundingBox() does now ignore empty boundingboxes of meshbuffers instead of adding them.
- IIrrXMLReader::getAttributeValueAsInt and IIrrXMLReader::getAttributeValueAsFloat can now return a custom default-value when the attribute is not found.
- core::string::split now handles ignoreEmptyTokens=false correct. Thanks @manni63 for bugreport: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=51551&p=299375#p299375
- Bugfix: Previously when some material had a texture matrix and another didn't those materials were still considered identical. Which had prevented correct switching between materials with and without texture matrices.
- Randomizer now returns range 0..randMax as documented and no longer 1..randMax as it did before. randMax got reduced by 1.
Note: You will generally get different numbers than before! If you need the exact old calculations, please check the corresponding sources in Irrlicht 1.8 in os.cpp/.h
- Resetting Randomizer with 0 or no longer breaks it (will be set to 1). Same for other numbers for which it wasn't defined.
- Add SMaterialLayer::TextureWrapW for cubemap texture wrap mode at W axis.
- Add cubemap texture support for D3D9 and OpenGL drivers.
- Do no longer re-calculate md2 frames when they don't change (thx @npc for reporting)
You can access the frustum boundingbox through the frustum itself.
This means cameras no longer show up in the node-collision of the SceneCollisionManager (showing up there because of their frustum bounding-box was too confusing).
- Fix problem in IrrlichtDevice::setResizable on X11 that caused window titlebars to hide occasionally under the taskbar in some systems (Ubuntu, Mint).
- Added new IRenderTarget interface.
- Replace the swprintf and snprintf defines by swprintf_irr and snprintf_irr to avoid conflicts with the standard libraries (and other libraries).
- XBox support removed as it would need DX8 (this was about the original XBox).
- Support for Direct3D 8 removed after svn revision 5052 due to lack of maintenance.
- _IRR_IMPLEMENT_MANAGED_MARSHALLING_BUGFIX removed. This was a bugfix for VS2003 (in combination with .NET) which we haven't supported in a while.
- Fix serializing colors as strings. Was previously mixing up strings with number-arrays and hex color values. Now using hex color values always, but also fixed the the handling when it get's number-array strings.
- Fix IAttributes::setAttribute implementation for textures (did do nothing before).
- Focus behavior of IGUIEnvironment now controllable (right-click focus, mouse-over focus). Disabled elements no longer get the focus unless users enforce it.
- Buttons can now now have 7 more image-states, 1 more sprite-state and the sprites are now scaleable.
- Spritebanks can now draw scaled sprites and are a little easier to use.
- Material renderers which offers blending feature (eg. EMT_TRANSPARENT_ALPHA_CHANNEL, EMT_ONETEXTURE_BLEND etc.) require SMaterial::BlendOperation set to other value than EBO_NONE.
- Removed support for built-in T&L variables in ASM/GLSL shaders (variables related to vertices eg. gl_MultiTexCoord0 are still supported). This change allow us to reduce CPU overhead in shader material renderers.
- IGUIEnvironment::hasFocus has now a parameter checkSubElements as subelements are usually seen as part of an element. Default unfortunately must be false due to backward compatibility.
- Add in IGUICheckBox: setDrawBackground, isDrawBackgroundEnabled, setDrawBorder, isDrawBorderEnabled
- IGUISpinBox now passes on the EGET_BUTTON_CLICKED, EGET_EDITBOX_CHANGED and EGET_EDITBOX_ENTER events from it's sub-elements.
- IGUISpinBox no longer validates values after each character type but only on KEY_ENTER and when losing focus. New behavior can be set with IGUISpinBox::setValidateOn
- IAttributes::getAttributeAs functions now can have a customizable default-parameter to return when attributeName is not found
- Added ECFN_DISABLED value (it works like ECFN_NEVER worked before) and changed ECFN_NEVER behaviour
(it works like its equivalent value in OpenGL/Direct3D).
- Removed boolean interface from IShaderConstantSetCallBack, please use integer interface instead of them.
- Add a LeakHunter class which can be enabled with compile-flag _IRR_COMPILE_WITH_LEAK_HUNTER_ to find leaking IReferenceCounted objects.
- Add _IRR_COMPILE_WITH_XML_ define to allow compiling Irrlicht without xml (patch written by curaga)
- Add functions to set/get cursor character and blinktime to IGUIEditBox
- Collada exporter calculates values for orthographic camera now on export
- Collada exporter now exports the camera up-vector correctly.
- Add IColladaMeshWriter::findGeometryNameForNode
- Add getters IGUIButton::isDrawBorderEnabled and IGUIButton::isDrawBackgroundEnabled
- changed CSkyBoxSceneNode to drawIndexedTriangleList instead of drawIndexedTriangleFan (because software renderers don't have fans.. and i needed the demo functionable)
- Update script to generate tutorial.html's in example folders. Add missing ones. Update existing ones. Thanks @Guillian J for noticing those were outdated.
- CIrrDeviceMacOSX now sets the SEvent.MouseInput Shift and Control values on mouse events like the other devices. Thanks @ Zero King for patch (#321)
- isWindowFocused in IrrDeviceSDL device now returns the input focus like the other devices. Before it was returning a mouse-over-window state.
- Prevent SDL device from dropping OpenGL resources on Win32 when setResizable was called with OpenGL driver. Thanks @ kas1e for reporting (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52083&start=0)
And thanks to http://www.bytehazard.com/articles/sdlres.html for the workaround.
- Fix isWindowActive when using SDL device. Before it was only active when the mouse was over the window. Thanks @ kas1e for reporting (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52083&start=0)
- Fix serialization of OverrideTextColorEnabled flag in CGUITab. Thanks @ chronologicaldot for reporting (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=52344&p=303891#p303891)
- Fix bug in cursor positions when compiled with newer Windows SDK's (v110 in VS2012) and running on Systems >= Windows Vista in windowed mode.
Thanks @Mustapha Tachouct for the bugreport and patch proposal. Also thanks @BakeMyCake for an earlier report.
- IOSOperator::getSysteMemory() no longer returns incorrect values with >2GB. Thanks @Eduline - human development for report and patch.
- Increase KEY_KEY_CODES_COUNT to fix problem with laptop keyboards which return the keycode 0xff for the function key. Thx @Klokancz for bugreport and patch.
- Fix bug when calling activateJoysticks on windows several times. It had appened joystick information instead of replacing it, thereby increasing joystick number on each call.
Only happened compiling with _IRR_COMPILE_WITH_DIRECTINPUT_JOYSTICK_ (which is the default). Linux and SDL implementation not affected.
Thx @Andrea Demetrio for the bugreport.
- Fix bug in fast_atof when reading floating point numbers with more than 16 digits past the dot. Those produced completely wrong results (sometimes even causing INF numbers).
This bug also did cause many meshloaders to have problems with certain meshes (basically all text-based formats are affected).
- Accuracy of fast_atof is back to older Irrlicht versions (fixes test warnings, usually not a noticable problem).
- Fix crash in eventhandling when calling remove() on a contextmenu while it has focus.
- CImageLoaderJPG::isALoadableFileFormat uses a test which allows to load more jpg formats (for example uncompressed jpg's). Thx @Yaron Cohen-Tal for report, test-image and his help with the patch.
- Update lights and renderTargetTexture tests to work with Windows 10 (can't have so tiny Windows anymore).
- Deprecate CMatrix4::transformBox as the result is no longer a boundingbox. Use CMatrix4::transformBoxEx instead (which has been available for a long time).
- Fix CSceneCollisionManager::getPickedNodeBB which could sometimes miss collisions.
- Add -U__STRICT_ANSI__ option to c::b project files to allow compiling with -std=c++11 and add an error when trying to compile with Irrlicht with __STRICT_ANSI__
- Tests give now a warning when stabilizing screenshots failed. Aslo trying more often now (a hack as taking screenshots otherwise fails often in windowed mode on some systems).
--------------------------
Changes in 1.8.3 (13.9.2015)
- Fix the fix for compiling on GCC5 (thanks to est31 for report and patch)
- Example 22 no longer select a random texture after loading a new texture (thanks at mongoose7 for reporting).
- Fix bug in IGUISkin serialization which messed up serialization of the button-pressed offsets (thanks at Midnight for reporting).
- IGUIStaticText::getTextHeight returns now the correct height for texts with newlines even WordWrap is not set.
- Crashfix for CGUIEditBox. CGUIEditBox::setMultiLine must break text when changed or other functions like getTextDimension can crash afterward for strings with newline characters.
- Fix compiling errors for c++ builder (thx @Greatwolf for many patches and @cfanderek for reminding)
- Initialized IColladaMeshWriter::GeometryWriting which was uninitialized.
- Fix linker trouble with irr::core::equalsByUl when compiling Irrlicht as managed code (thx @ Memorial76 for a report + testcase)
- Fix crashes in CCubeSceneNode::clone and CSphereSceneNode::clone (reported by marsupial)
- Fix the clipping in the listbox drawing which was only showing the right line of the sunken pane (reported by Mloren and Abraxas).
- Initialize slider in example 05 correct (reported by Zerochen)
- Fix crash in CMeshSceneNode::clone when the mesh had no shadow (reported by christianclavet, bug-fix found by Nadro)
--------------------------
Changes in 1.8 (7.11.2012)
- Let sphere mesh use full opaque color, just as all the other ones do
- Gcc on Win32 (MinGW) now also works with the _w file access functions when compiled with _IRR_WCHAR_FILESYSTEM. (thx @ alexzk for reporting compile troubles)
- Fix a bunch of off-by one errors in irr::core::string in functions equals_substring_ignore_case, findFirst, findFirstChar, findNext, findLast, findLastChar, replace, remove and removeChars.
This prevents some potential memory access errors, find functions no longer try to find the \0, replace no longer replaces the \0 and remove no longer tries to remove it (which did remove the last character instead).
- matrix4::setRotationAxisRadians added
- user clipplanes fixed
- Skip rendering of lines, points, and polygons, as these lead to crahses due to wrong access to the vertex lists. A fix would need major rewrite of the vertex cache, or at least some other render methods.
- Add mipmap generation for makeColorKeyTexture
- Add another saveScene overload which allows to pass in a user-created XMLWriter. Patch suggested by eversilver.
- Colladareader now creates the ambient-light correct instead of creating a point-light for it.
- Add new parameter to array reallocate function. This prevents a reallocation in case the array would become smaller. As the reallocation operation is quite time consuming, this can be avoided on request now, on the expense of more memory consumption.
- Add IAnimatedMeshSceneNode::getLoopMode (asked for by JLouisB)
- CSceneNodeAnimatorCameraFPS now resets the key-input when it was disabled (thx @ gerdb for reporting and patch-proposal)
- Properly destroy OpenGL resources on linux (thx @curaga for the patch)
- Fix diplay bux in the attribute-panel of the GUIEditor. Fixes bug 3517314 (thx @Darkcoder for reporting).
- Allow caching cursor position on X11 to work around slow XQueryPointer calls (thx @Hendu for reporting+patch proposal)
- Make sure after EGET_EDITBOX_ENTER and EGET_COMBO_BOX_CHANGED event processing no more code is executed for the corresponding editbox or combobox objects to allow clearing the environment on those actions (see comments on bug-id 2995838).
- Fix string::replace which failed replacing substrings at the end when the replacement was longer
- Struct packing works now with gcc 4.7 changes on MinGW (thx @Sudi for reporting).
- Struct packing uses now same solution throughout (by including headers in corresponding places)
- User can now set characters used for decimal point in fast_atof for localisation.
- Add parameter useAlphaChannel to second IGUIEnvironment::addImage function.
- Get rid of unnecessary warning "Could not load sprite bank because the file does not exist" for "#defaultfont".
- Fix MRT disabling. Bug found and fixed by hendu.
- core:::array::reallocate returning now immediately when it has nothing to do. Should reduce a lot of memory thrashing on irrArrays.
- Start mesh animations at first OnAnimate , before start-frame was rather random. Thx @Auria for reporting and patch proposal.
- renderTargetTexture now working with ECF_R5G6B5
- add -fPic in c::b linux fast math shared build.
- Fix by Auria for starting the animated meshes only at first OnAnimate instead of at random times and animation frames.
- Add support for MAX_COMBINED_TEXTURES, which allows more texture support than with the original fixed pipeline texture check under OpenGL. Now, more than 4 textures should also work with newer gfx cards and drivers, which often only support 4 fixed pipeline textures.
- triangle3d::isPointInsideFast now using some epsilon to catch all points on the borders.
- triangle3d::getIntersectionOfPlaneWithLine calculates now with higher precision for more exact results.
- triangle3d::isOnSameSide (used by isPointInside) calculates now with higher precision and uses some epsilon to make it work with larger integers and less floating point troubles. Slightly slower now.
- new function equalsByUlp to test for spacing between floating point numbers.
- speedup for collada writing.
- speedup for xml-writing.
- Fix 8bit grey image TGAs, which were not working due to missing palette. Also switched to RGB8 format, as otherwise a loss in precision would occur. Thanks to Klunk for the error report and a test image.
- fixed issues with a D3D driver and Aero effects.
- Fix font-drawing in CGUIButton to use EGDF_BUTTON again (thx @DJLinux for reporting).
- Add texture cache with proper reference handling. This avoids deletion of textures while still being active on the GPU. Test case and fix by m(att)giuca
- CFileSystem::removeFileArchive now checking for normalized path
- Fix zip's with passwords on 64-bit systems (thx @ Dr. Gladman for writing the bugfix)
- replace asserts in tests with macro assert_log to allow running all tests through on problems.
- added IGUIElement::setName and IGUIElement::getName (similar to ISceneNode)
- irr::s64 support
- line2d::getClosestPoint can now also get the closest point on the line additional to only checking for closest point on the line-segment.
- avoid division by zero in line2d::getClosestPoint when start- and endpoint are identical
- Support for sw drivers under OSX
- Fix font-loading which got broken by fixed xml-loading. Thanks @ pc0de for finding and providing a test and patch.
- Don't crash draw2DSpriteBatch when it get's no textures.
- Add support for int passing in setShaderConstant
- Support for better collada texture wrapping support on loading.
- Fix for render context change where only the window id is given. We now try to change only the window ID, keeping context and display unchanged. Suggestion by vovo4ka from the forum.
- XML-reader now ignores all whitespace-only EXN_TEXT elements as old way didn't work in cross-platform way (and arguably also not well on Windows).
- line2d::intersectWith and and line2d::getClosestPoint work now also with integers.
- line2d::getMiddle and line3d::getMiddle work now also with integers. But can be slower for compilers which are not optimizing division by 2 to multiplication by 0.5 for floats.
- Add Nadro's initial Cg support. Example 10 is enhanced to allow also Cg shaders.
- Add mipmap support from FBO extension, patch by Nadro.
- Add vertex optimization algorithm submitted by curaga
- rename texureBlend functions to textureBlend
- Add threshold for slerp calculation, switching between linear and slerp at this point.
- Fix for bug 3401933 - vertex color interpolation with shadow volumes in the scene
- Fixed bug in button sprites reported by RdR
- Fixed button state sprite animations for pressed, focused and hovered.
- Added serialization for terrain smooth factor, patch by RdR
- Implemented more button states for sprite banks, patch submitted by RdR
- Add IGUIEnvironment::getHovered to get the element most recently known to be under the mouse cursor
- Add FPS settings for animated meshes, which allows to push animation speed from files to Irrlicht animation system
- Maya camera updates
- Add support for bsp brush entities. Written by Hendu.
- weighted normals recalculation fixed
- Billboard improvements
- API docs updates
- triangle selector improvements
- OSX improvements by Auria
- Add new methods for adding and removing file archives based on ifilearchive pointers.
- Add getBackgroundColor, isDrawBackgroundEnabled and isDrawBorderEnabled to IGUIStaticText (thx 4 patch from Nalin).
- Reduction of multiple skinning the same mesh and frame in one render cycle
- Added ISceneNodeAnimatorCameraFPS::getKeyMap and a new ISceneNodeAnimatorCameraFPS::setKeyMap.
- CSceneNodeAnimatorCameraFPS uses now SKeyMap instead of SCamKeyMap (structs were identical which was confusing and there wasn't any explanation in comments, so I decided to simplify it).
- Add some workaround to MeshViewer to show how we can currently fix the FPS-cam when users to alt-tab while moving. We can improve that some day when we have focus-events, but this works for now.
- Fix LZMA decompression
- Ply normal fixes
- HW buffers only support rendering with both vertex and index buffers
- Enables VBOs for water node
- Octree support for non-standard vertex meshes
- Fix rotationFromTo
- Added ConstIterator
- Fix for getScreenCoordinatesFrom3DPosition to use proper RTT sizes
- IGUIEditBox: fix crash that happened when wordwrapping was enabled, spaces were entered beyond the border and then cursor-key was pressed.
- IGUIEditBox::setDrawBackground added.
- CGUISkin::draw3DSunkenPane no longer ignores fillBackGround in non-flat mode. Also borderlines are no longer drawn overlapping to avoid ugly corners.
- Renamed IOSOperator::getOperationSystemVersion to getOperatingSystemVersion. Changed return type from wchar_t to core::stringc, as that's the internal representation the name is built on.
- Added IGUITabControl::insertTab, IGUITabControl::removeTab, IGUITabControl::clear and IGUITabControl::getTabAt
- Added the ability to open an archive from an IReadFile*, added a FileToHeader tool with instructions of how to make a portable app that consists of a single executable file.
- The Makefile now creates a symlink from the soname to the binary name during install. Binary compatibility is only confirmed between same minor releases.
- The loader selection process now consistently checks loader lists in reverse order, so new loaders added to Irrlicht override the internal ones. This applies when adding external mesh, image, scene and archive loaders, image writers, plus node, animator and GUI element factories.
- Fixed panel scrollbars in GUI editor, reported by Armen
- Fix b3d loading of files with mixed mesh/bone sections.
- Fix particle emitters which used integer random numbers so far. The distributions of the particles should be much better (and the code also somewhat faster) now.
- Add new random method frand: Returns a random number in the interval [0..1] and gives better distributions than using fmodf on the integer number.
- Add node parameter to saveScene and loadScene. saveScene saves the given node and all descendants to the file (if 0, the full scene is saved as before). loadScene loads all elements of the scene as childs of the given node. As before, 0 would load the file on the top level (scenemanager).
- Add method to make a filename relative to a given directory.
- Fix setMesh to correctly update the joints cache.
- Fix setting transition time of skinned meshes back to 0.
- Add some getters to IGUIImage: getImage, getColor
- Fix OpenGL FBODepthTexture to create less overhead
- API change: Added write only lock mode for textures. The lock method has changed the signature and uses an enum parameter now instead of a bool. The default is still to lock for read/write (previously 'false'). The old 'true' value should be replaced by ETLM_READ_ONLY.
- Speedup deleting of particles
- Add function IParticleSystemSceneNode::clearParticles
- Fix RTT render states under OpenGL
- Fix AntiAliasing setup under Windows/OpenGL in case no AA is available
- Fix transformation matrices when RTT used
- API change: getScreenCoordinatesFrom3DPosition has a new parameter, which needs to be set to true to get the original behavior. Now, the method returns coordinates which would fit as render coordinates of a currently enabled viewport. With the parameter set to true the result would fit only after the viewport is reset to full window rendering.
- Add flag and method to disable clipping of the text to the gui element rectangle in GUI static text.
- addShadowVolumeSceneNode now replaces an existing shadow. One should avoid to call this method multiple times without changing any parameter, as it is quite time consuming and cannot recognize the duplicate calls.
- Add function IGUIEnvironment::removeFont (TODO: Does not remove the texture from cache so far)
- Functions in IMeshCache expecting IAnimatedMesh* parameters removed as similar functions with IMesh* can be used since a while. Fixes also problems when IAnimatedMesh* got upcasted to IMesh*. (thx @ Greenya for reporting)
- The following functions will now use a "ISceneNode *" instead of a "const ISceneNode *":
ITriangleSelector::getSceneNodeForTriangle, ISceneNodeAnimatorCollisionResponse::getCollisionNode, ISceneCollisionManager::getCollisionPoint and ISceneCollisionManager::getCollisionResultPosition.
As collision functions often are followed by changing node positions users where so far forced to using const_casts (found by Greenya).
- Add vector3d::getAs3Values (patch provided by slavik262)
- Add function to SViewFrustum to get corners of the near plane (patch provided by Matt Kline, aka slavik262)
- ParticleFadeOutAffector::setFadeOutTime can no longer be set to invalid values
- ParticleFadeOutAffector uses now throughout u32 for fadeOutTime (found by greenya)
- Add missing access function CParticleSystemSceneNode::getAffectors() (seen by B@z)
- Add missing setters/getters for particle emitters (seen by B@z)
- Compile-defines can now be disabled from Makefiles/Projectfiles instead of having to change IrrCompileConfig.h each time.
- IGUITabControl::setActiveTab should only take IGUITab* and not IGUIElement* (thx to greenya for finding)
- Fix cursor cleanup under Linux when using multiple devices
- Fix collada parser
- Fix MRT reset under D3D
- Add a generic attribute interface for querying video driver attributes which are not necessarily of type bool. This interface allows to check certain supported features, such as the number of user clip planes, supported lights and textures, MRTs, and other things. The interface might change in the future, but it's fully functional already. The supported attributes are listed in the API docs of the function:
The following names can be queried for the given types:
* MaxTextures (int) The maximum number of simultaneous textures supported by the driver. This can be less than the supported number of textures of the driver. Use _IRR_MATERIAL_MAX_TEXTURES_ to adapt the number.
* MaxSupportedTextures (int) The maximum number of simultaneous textures supported by the fixed function pipeline of the (hw) driver. The actual supported number of textures supported by the engine can be lower.
* MaxLights (int) Number of hardware lights supported in the fixed function pipeline of the driver, typically 6-8. Use light manager or deferred shading for more.
- add CGUIEditBox::getOverrideColor and CGUIEditBox::isOverrideColorEnabled
- add dimension2d::operator-
- Add logging level ELL_DEBUG
- Add parameter DisplayAdapter to creation params to allow selecting the card when more than one card is in the system.
- Added support for custom cursors
- WM_SYSCOMMAND - SC_KEYMENU message is now ignored (F10 and ALT in Win32 windowed mode)
- Avoid argument lookup ambiguity in swap when used in combination with stl. Using same trick as boost now and use 2 different template parameters in it.
- Add support for vertex_array_bgra extension in OpenGL driver. This will speed up OpenGL rendering quite a lot as it skips the silly color conversion thing we have to do otherwise.
- Replace raw xml char implementation with template struct in order to decouple the type from POD types. May also help for 64bit problems or changes needed there.
- Bugfix: vector2d.normalize() and vector3d.normalize() had returned wrong results with very short vectors since Irrlicht 1.5. Thanks to Willem Swart for Bugreport + testcase.
- Unknown keymappings now use the X11 keycode instead of 0 to make such keys at least usable in games.
- KeyMapping for KeyInput.Key on X11 ignores states like shift&ctrl now like on Windows.
- Additional keymappings for X11 (tested with german and us keyboards which seem to work now in all cases).
- Fix crash in multiline editbox when pasting several lines into it on Windows (found by Reiko)
- example 09.Meshviewer no longer catches keys while a modal dialog is open
- Fix SSharedMeshBuffer
- Fix right handed ortho matrix
- editbox no longer displays cursor when disabled
- editbox autoscrolling now at least works good enough to actually show the text which the user is typing in.
- CGUIScrollBar passes unused mousemove-events now to parent element. Fixes focus-bug in ComboBox reported by REDDemon here: http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=43474&highlight=
- Fix IGUIScrollBar setMax and setMin which had been restricted wrongly (reported by REDDemon)
- Fix CNullDriver::createImage - Creating the image from a texture-rectangle which doesn't start at 0,0 works now again (thx @ ceyron for bugreport+testcase)
- Menu no longer sets highlight state when clicking disabled menu-item (reported by Mloren)
Note that it couldn't be completely fixed for the SpinBox without breaking the interface, so for that element you have to enforce this by calling for example element->setValue(element->getValue()) once.
- Fix CXMLReaderImpl::getAttributeValueAsInt which returned wrong values with large integers (thx to squisher for finding)
- Fix bug in dimension2d::getInterpolated that caused wrong results when used with integers as template parameter. (thx to Greenya for noticing a warning which made me look over this code).
- Fix octree with frustum+parent checks enabled (didn't clip at all before). Now using plane-checks instead of edge-checks for frustum-box intersection.
- Define sorting order for vector2d and vector3d in operators <, <=, > and >= to fix bugs 2783509 and 2783510. Operators order now by X,Y,Z and use float tolerances.
- refactoring: E_ATTRIBUTE_TYPE and IAttribute have now own headers
- CStringWArrayAttribute speedup
- SceneNodeAnimatorFollowSpline can now loop and pingpong
- Meshviewer.example got some fast-scale buttons.
- Support AES-encrypted zip files. Should work with 128, 196, and 256 bit AES. This addition also adds a new PRNG, SHA, and other algorithms to the engine, though no interface is yet added for them. The implementation of the encryption algorithms is provided by Dr Brian Gladman.
- Checkbox uses now disabled text color when disabled.
- Changed colors for window-title caption to keep them readable when not active.
- Draw sub-menus to left side if they would be outside main-window otherwise.
- Give ListBox better defaults for the ScrollBar stepsizes.
- Double and triple click events now for each mouse-button. Old events for that got removed.
- Fix adding archives twice, which caused multiple archives of the same name and type covering each other. This one required a texture name change from using backslashes to slashes under Windows.
- Give access to texture mipmaps. You can provide custom mipmap textures upon generation, regeneration, and locking.
Make sure the provided data is large enough and covers all miplevels. Also the returned pointer (from lock) will only cover the smaller data of the mipmap level dimension chosen (level 0 is the original texture).
- new vector3d::getSphericalCoordinateAngles method.
- new triangle3d::isTotalOutsideBox method.
- Newly introduced VertexManipulator interface. This allows for very easy creation of vertex manipulation algorithms. Several manipulators, e.g. vertex color changer and transformation algorithms are already available.
- Fix pingpong for CSceneNodeAnimatorFlyStraight (found by gbox)
- Fix bug with IGUIEditBox where the cursor position is reset on text change.
- Make sure the window top-left corner on Windows is not negative on start so that Windows sytem-menu is always visible.
- Fix problem that the window did sometimes not get the keyboard focus in X11 in fullscreen. Add more debug output in case focus grabbing goes wrong.
- Fix screensize in videodriver when we didn't get the requested window size. This also prevents that gui-clicks are no longer synchronized with gui-drawing and elements can't be hit anymore.
- Bugfix: Prevent a crash when getTypeName was called for the guienvironment. EGUIET_ELEMENT got changed for this.
- Bugfix: Horizontal centered font with linebreaks draw now all lines. For example multiline TextSceneNodes work again.
- Bugfix: spinbox can no longer get in an endless loop due to floating point rounding error (found by slavik262)
- !!API change!! Disabled AntiAliasing of Lines in material default
Please enable this manually per material when sure that it won't lead to SW rendering.
- IGUIComboBox: clicking on the statictext displaying the active selection does now close and open listbox correctly. (Bug found by Reiko)
- Scrollbuttons in IGUITabControl adapt now to tab-height.
- Fix texturing of cylinder mesh
- Fix modal dialog position (found by LoneBoco: http://sourceforge.net/tracker/?func=detail&aid=2900266&group_id=74339&atid=540676)
- Fix DMF loading
- Fixing left+right special keys (ctrl, shift, alt) on Win32 (thanks to pc0de for good patch-ideas).
- Make stringarrays for enums in IGUISkin a little safer
- Add support for keys KEY_PRINT, KEY_HOME (on numpad) and KEY_NUMLOCK on Linux.
- Renamed some methods in ISkinnedMesh to match the official Irrlicht naming scheme according to createXXX()
- Change debug data to draw using lines instead of arrows, which is much faster. Patch by pc0de
- Fix a bug with FPS camera animator causing stutters. Patch by FuzzYspo0N
- Fix scrolling controls in CGUITabControl
- Fix a bug when getting optimal texture size in D3D drivers, by Jetro Lauha (tonic)
- Added EGDS_TITLEBARTEXT_DISTANCE_X and EGDS_TITLEBARTEXT_DISTANCE_Y to GUI, submitted by FuzzYspo0N
- Fix for UFT8 filenames displayed in file dialog, patch by MadHyde.
- Added const method for array::binary_search, potentially slow as it doesn't sort the list!
- Add support for scaling button images.
- Irrlicht can now come with multiple device types compiled in, the device to use is selected by SIrrlichtCreationParameters.DeviceType. This defaults to EIDT_BEST which automatically select the best device available starting with native, then X11, SDL and finally the console.
- Added support for EXP2 fog distribution. This required a change in the setFog parameters where now an enum value instead of the bool linear is given.
- IFileSystem changes:
- Renamed the following functions-
IFileArchive::getArchiveType to getType
IFileSystem::registerFileArchive to addFileArchive
IFileSystem::unregisterFileArchive to removeFileArchive
IFileArchive::openFile to createAndOpenFile
- New enum, E_FILE_ARCHIVE_TYPE. getType on IArchiveLoader and IFileArchive now both return this.
- IFileSystem::addFileArchive takes a parameter to specify the archive type rather always using the file extension. IFileSystem::addZipFileArchive, addFolderFileArchive and addPakFileArchive now use this but these functions are now marked as deprecated. Users should now use addFileArchive instead.
- Added TAR archive loader.
- The ZIP archive loader can now load gzip files, combined with the TAR loader this means Irrlicht now has native support for .tar.gz
Currently this must be done in two calls, for example:
- Direct3D now also uses screen coordinates in 2d mode, just like OpenGL. This means that screen coords are going from 0..ScreenWidth and 0..ScreenHeight instead of -1..1.
- ALT+F4 keypress now closes Windows SDL device
- Allow Direct3D drivers in SDL, patch by Halifax
- Added compiler error when attempting to compile with VC6.
- Use setWindowTextA in Windows device for WIN64 platform, posted by veegun
- ELL_ERROR log events are now created when shaders fail to compile or link, reported by Halan
- irrList now uses irrAllocator, fixed by Nox
- Added IGUIWindow::setDraggable and IGUIWindow::isDraggable, by Nox
- Added SGI RGB file reader by Gary Conway, for loading Silicon Graphics .rgb, .rgba, .sgi, .int and .inta textures
- Renamed setResizeAble to setResizable
- Added new device method minimizeWindow which minimizes the window (just as if the minimize button has been clicked).
- SkyDome is now serialized correctly
- Added PLY mesh reader and writer
- Ensure ListBox on combo box doesn't hang off the bottom of the GUI root, by Matthias Specht
- Made IGUIElements recalculate clipping rectangle after setNotClipped, reported by Aelis440
- New scene parameter B3D_LOADER_IGNORE_MIPMAP_FLAG to ignore the often missing mipmap flag in b3d files. If this parameter is true, the old pre Irrlicht-1.5 behavior is restored.
- Added Mipmap LOD Bias attribute to MaterialLayer.
- Added ColorMask support to selectively disable color planes on rendering.
- Added support for all available depth test functions.
- Add an outNode to getCollisionPoint() that returns the scene node that was hit, as well as the triangle.
- Initial support for Alpha To Coverage, needs some more fixing until it works on all supported platforms.
- Added support for Anti-Aliasing modes per material
- Added an ICollisionCallback to ISceneNodeAnimatorCollisionResponse, to inform the application that a collision has occurred. Thanks to garrittg for this.
- Added an startPosition parameter to createFlyCircleAnimator() to allow starting the animator at any position on the circle.
- Many uses of dimension2d<s32> changed to dimension2d<u32>, including IImage, ITexture and screen dimensions. You will have to change (at least) createDevice() calls to use dimension2d<u32>
- Added Doublebuffer flag to SIrrCreationParameters, for better finetuning
- Added Stereo-Framebuffer support for professional OpenGL cards
- Added IFileSystem::createMemoryWriteFile() to allow creation of an IWriteFile interface that uses an application supplied memory buffer.
- Added an IVideoDriver::writeImageToFile() overload that can take an IWriteFile interface.
- (Internal) Replaced CMemoryReadFile with CMemoryFile, that also implements an IWriteFile interface.
- Added an optional light manager to the scene manager to allow the user application to turn lights on and off during scene rendering. This can be used to produce "zoned" lighting. See example 20.ManagedLights.
- Added a method to flip the Y movement of the FPS camera.
- The Anisotropy filter can now be set to the AF value per texture layer. So no forced MAX_ANISOTROPY anymore. .irr files will probably fail, though.
- AntiAlias parameter in SIrrCreationParameters is now an u8 value specifying the multisampling level (0 for disabled, 4,6,8, and others for anti-aliasing)
- D3D devices use DISCARD for windowed renderbuffers now, can be faster.
- Changed behavior of PixelBlend16() / PixelBlend16_simd() so that they treat the 1 bit alpha of the source pixel as boolean, i.e. they draw either the source pixel, or the destination pixel, rather than "blending". (Issue revealed by the fix to IVideoDriver::makeColorKeyTexture()).
- IVideoDriver::makeColorKeyTexture() bug fixed so that only alphas, not whole texel colors, are zeroed. An optional parameter allows using the old (buggy) behavior for backwards compatibility.
- Checnged collision checks for children of invisible elements to also be ignored (as they're actually invisible due to inheritance).
- Fix terrain to use 32bit only when necessary, make terrain use hw buffers. Heightmap loading and height calculation fixed. Visibility and LOD calculations updated.
- Added a test suite in the /tests directory. This can be used to perform regression tests, and should be updated with new tests to verify fixes or validate new features.
- Changed the preferred way of altering light node's radius: Use the new member methods of ILightSceneNode instead of directly modifying the SLight structure.
- Changed the initial attenuation back to (0,1/radius,0). To override this value simply change the attenuation in the SLight (lightnode->getLightData().Attenuation.set(x,y,z))
- Dirty fix for OSX device setResizable and a bug fix to do with resizing the device.
- Terrain heightmap and texture were flipped in order to draw them as expected (looking onto the terrain from high above will just look like the actual texture/heightmap).
- Significant internal change to the way that FPS camera jump speed and collision response animator gravity interact. The behavior is now much more realistic, but it will require you to adjust your jump speed and gravity.
- Skybox won't be culled anymore by nearplane or farplane.
- BBoxes of animated meshes (skinned meshes) are updated again.
- Lost devices (as found with D3D) are properly handled now. So the screen can be resized or minimized without crashing the app.
- Renamed IGUIElement::setRelativePosition(const core::rect<f32>& r) to IGUIElement::setRelativePositionProportional(), as it has radically different functionality from setRelativePosition(const core::rect<s32>& r)
- Added IGUIElement::setRelativePosition(const core::position2di & position) to set a new position while retaining the existing height and width.
- Many Collada fixes. z_up coords are supported now, texture coords are properly loaded. Transparency is supported.
- Camera scene node rotation and target can now be bound together so that changing one automatically changes the other (as the FPS camera has always done). See ICameraSceneNode::bindTargetAndRotation()
- Removed the extra libpng files for OSX. OSX now also uses the default libpng.
- Enhanced PCX support with some more color formats and write support.
- Particles can be scaled during animations. Particle scaling needs to happen in the emitter now, instead of in the Particle system scene node. Deprecation methods will guide the user.
- Basic support for joystick input events on Windows, Linux, SDL and OSX. Tested with wired Logitech and Thrustmaster wired controllers and XBox 360 wireless controller ( http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver )
- Fixed scaled octree nodes being incorrectly frustum culled.
- FSAA under OpenGL and Win32 added. Now all hw drivers and platforms should support it.
- Unlimited RTT fix for D3D systems. Depth buffers are now shared if possible, otherwise a new depth buffer is generated. In order to save VidMem one should create RTTs starting with the largest one.
- Avoid RTTs with nonFBO-support under OpenGL which are larger than the screen. Since we rely on rendering into textures in this case we need to clamp the size by the screensize.
- Fixes for getAbsoluteFilename under Linux in order to return a filename instead of en empty string in case the file doesn't exist.
- Use absolute path names when creating / finding textures.
- Font tool implementation for Linux with xft, by Neil Burlock.
- Support for normals and UV coords from DeclData in .x files.
- Modified line2d<T>::intersectWith() to cover more cases.
- Added IVideoDriver::drawPixel().
- Moved the window pointer from endScene to beginScene, as this is required for OpenGL support of external window pointers.
- Fix for terrain culling.
- Added minimize button to win32 window (if resizable)
- Major API change: RTTs are now created via addRenderTargetTexture instead of createRenderTargetTexture, which allows to retrieve them from the texture cache, but also changes the way of removing the RTTs, and especially one must not drop the pointer anymore.
- disableFeature can be used to override feature support of the video driver.
- draw2DImage can now also handle RTTs under OpenGL (which were flipped before).
- Ogre mesh format fixes for proper texture support.
- Added .obj mesh writer.
- Some core::string constructors made explicit to avoid unintended conversions. Just add core::stringc() or core::stringw() around the old code to avoid warnings.
- IdentityMatrix is now a properly defined global, with external visibility on all platforms.
- Bugfix for context releases with glx 1.3 on error.
- Removed constraints for sizes of the terrain scene node.
- Support for 32bit indices in a special MeshBuffer class.
- Changed interpretation of MaterialTypeParam==0 in transparent materials. Now it's consistent with all other values, but one has to set the value to 0.5 to get the old behavior (slightly faster rendering, but no smooth borders)
- Replaced transformBox by transformBoxEx in some internal methods to avoid major malfunction of the transformations.
- Enable use of other meshes for shadow mesh generation, can be used to speed up shadow generation and rendering for complex meshes. Patch based on a version by tonic.
- Fixed usage of SIrrCreationParameters struct, which dind't have copy constructor and assignment operator anymore, since the Irrlicht version string was made const.
- Added support for read-only locking of textures. Can speed up those calls.
- Added support for locking RTTs under OpenGL.
- Implementation of UserData events from system events.
- ICameraSceneNode::setIsOrthogonal replaced by a parameter to setProjectionMatrix.
- All meshbuffers are now dynamically allocated to avoid problems with grabbed buffers, which may be deleted before the last drop happens (due to static memory allocation).
- Enhanced scene graph traversal with example from rogerborg.
- FPS camera disabling of event receiver works better now.
- scene deserialization allows for a user defined callback after a new scene node is created.
- Hardware accelerated Vertex and Index Buffer support finally integrated into Irrlicht. Thanks to a resource handling idea by Klasker and the almost immediate implementation by Luke, Irrlicht now supports VBOs under OpenGL and D3D.
Hardware buffers make rendering the same vertices much faster. To use this feature with a mesh, simply set a usage type via MeshBuffer->setHardwareMappingHint(scene::EHM_STATIC). The driver will upload the vertices and indices on the next draw and reuse this information without the need to upload it each frame.
Vertex and Index buffers can also be updated separately, which is e.g. useful for the terrain node's LOD.
- Changed FBO creation according to Nadro's patch. Seems to have zbuffer problems currently.
- Update to libpng 1.2.29
- Compiler flag for PerfHUD support added.
- recalculateNormals and tangent space creation enhancements by ryanclark.
- Added getColorFormat methods for device and driver, returning the color format of the device's window and the driver's framebuffer.
- Added isFullscreen method.
- Added isWindowFocused and isWindowMinimized methods.
- Screenshots are now always made from the frontbuffer, so always the last completely rendered image is captured. However, overlapping windows may corrupt those parts of the screenshot (as was previously happening with d3d already).
- New device creation parameter to disable Irrlicht's system event handling.
- New device creation parameter to specify depth bits.
- New device creation parameter to request alpha channel in framebuffer.
- Draw2DImage methods under OpenGL now also handle RTTs correctly.
- Fixed RTT bug which lead to strangely clamped textures.
- Speed improvement for screenshots on some Intel cards under OpenGL.
- My3D file loader fixed.
- Terrain mesh performance increased.
- Fixed mem leak in cube node.
- Compiler errors in shaders won't corrupt the material renderer list anymore.
- Quake3 shader files now have properly working texture matrices again.
- .obj files now won't duplicate vertices unnecessarily. This allows recalculation of smooth normals and other things, and is also faster when rendering. The loading is a little slower now.
They also support normal maps and texture clamping now. Group support added, can be ignored via scene manager attribute scene::OBJ_LOADER_IGNORE_GROUPS.
Normals will be calculated if the file doesn't provide them.
- MeshBuffers can now access the elements of the S3DVertex base class in all vertex types directly, instead of using the getVertices() pointer access. This simplifies simple mesh manipulations as it does not require a switch statement over all vertex types.
- Fixed a bug in CGUISpriteBank which caused a crash when a non-looping animated sprite reached the end of its animation.
- Modal screens no longer flash invisible children when rejecting a focus change.
- Finally added StarSonata patch with table element and TabControl additions. Table is based on MultiColor listbox by Acki, and has loads of changes by CuteAlien.
- Unified the handling of zwrite enable with transparent materials on all hw accelerated drivers. This means that all transparent materials will now disable ZWrite, ignoring the material flag.
There is a scene manager attribute, though, which will revert this behavior to the usual SMaterial driven way. Simply call
SceneManager->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT, true) and set the SMaterial flag as desired.
- Some changes for texture matrices in q3 shaders.
- Added BlindSide's irrAllocator patch for proper TextureMatrix release under Win32 with any CRT library.
- Added VC9 project files.
- Added getEmitter for particle system scene nodes.
- irrMap fix to make root node always black, by rogerborg.
- Possible core dump fixed in particle system node, by CuteAlien.
- Mem leak fixed in b3d loader.
- Avoid double rendering of child nodes of joints.
- Support for d3d draw2dimage clipping by CuteAlien.
- Fixed an animation transition bug, pointed out by wuallen.
- Fixed the major problem with OpenGL drivers, that claim to be 2.x compatible, but don't offer NPOT support (well, they do, but only in sw rendering...). Now we check for the extension string only.
- Fixed .obj loader bug which inserted vertices in wrong buffers.
- Fixed the FollowSpline animator to avoid crashes when only one waypoint is given.
- OpenGL VolumeShadow now uses glPolygonOffset to avoid zbuffer artifacts.
- Fixed meshbuffer corruption in append methods.
- Fixed mem leaks in irrArray.
- Fixed minor bugs in ISceneNode and ISceneManager.
- Fixed the MeshCache handling of GeometryCreator meshes.
- Terrain LOD bugfix.
- Some Collada 1.3 loader enhancements and bug fixes.
- Fixed a bug in CGUISpriteBank which caused a crash when a non-looping animated sprite reached the end of its animation.
- Enhanced the .obj loader with the patch from ryanclark. This allows for recalculation of smoothed normals of the mesh, also should decrease the tri count on some meshes.
- Avoid the global Logger to be destroyed too early.
- Support for Milkshape 1.8 files, also with multiple weights per joint.
- The config file now also supports _IRR_OSX_PLATFORM_ and _IRR_USE_OSX_DEVICE_. This allows to use the Linux device (X11 support) on OSX.
- Avoid terrain scene node crash when heightmap cannot be loaded.
- Speed improvements for WaterSceneNode.
- FlyCircle animator now also works for upvectors (Direction parameter) which are not (0,1,0). Is also faster now, since most calculations are done on init. Thanks to Dorth for working on this.
- The 3ds loader correctly creates a texture matrix when texture tiling properties are found in the file.
- Fix for S3DVertex comparison operators. Used some wrong logic.
- Bugfix getCurrentRenderTargetSize in D3D drivers. Due to signature differences a wrong virtual method was chosen. Thanks to Jiang for finding it.
- Major API change: All material properties which are available per texture layer (curently texture, texture matrix, texture filters, and texture wrap mode) are separated into a new struct SMaterialLayer. You can access them via the array TextureLayer[] in SMaterial. The texture matrix methods in SMaterial are still alive, and also textures can be accessed via methods in SMaterial now. But still, many places in user code need some update (usually changing material.Textures[i] to material.TextureLayer[i].Texture etc.)
- Major API rewriting for proper const usage. Now, most getter methods are const and so are the larger parameters and return values. Moreover, many methods taking only unsigned numbers now use u32 instead of s32 in order to recognize this limitation from the method's signature.
- Fixed Skybox texture orientations. They are now displayed non-flipped. Existing skyboxes have to be changed, though: Exchange left and right texture. Textures from Terragen and other tools can be used directly, now. Quake maps will also need the right/left exchange.
- fixed the keyboard autorepeat difference between Linux and Windows. Thanks to denton we now have only KeyPressed events on both systems in case of autorepeat.
- Point sprite support in the driver. Point sprites use just one 3d vertex and a size to create a textured billboard on the GPU. This can provide fast particle systems, especially in combination with shaders. The proper particle extension will follow later on as it needs some more refactoring.
- Added Spot light type for dynamic lights. Note that both position and direction for all dynamic lights are now determined by the LightSceneNode, the SLight attributes are only used for internal purposes.
API change! One can easily work around this change by setting the LightSceneNode's Position and Rotation instead of the SLight's. This change won't provoke a compile error, though, and can hence go unrecognized besides the visual problems.
The lights use a default direction (0,0,-1) which is rotated by the usual scene node transformations and can hence be modified by scene node animators.
A change in the Radius usage can lead to strange artifacts. Just increase the Radius in this case. further handling of Radius is to be discussed.
- Added per pixel fog support for OpenGL.
- Added driver support for user defined clip planes, based on mandrav's patch.
The OpenGL version is more picky about ModelView matrices, so it's best to set the projection plane at the time it is used.
- A new MeshBuffer implementation is publicly available. It supports a shared vertex list for all MeshBuffers, used for MS3D meshes.
- MeshBuffers can recalculate their BoundingBoxes on their own now, no need for MeshManipulators. New append methods help to merge MeshBuffers. take care that the types match!
- The new texture generation mode is working. With ETCF_NO_ALPHA_CHANNEL textures are generated without ALPHA bits reserved.
- D3D9 hardware mipmap updates are re-enabled, problems should be reported.
- Fixed the hillplane mesh to work with non-quadratic dimensions as well. Changed the interface also, so use a u32 dimension to specify the tilecount now.
- Added getSystemMemory and getProcessorSpeedMHz for Windows and Linux to the OSOperator, submitted by Vitek.
-------------------------------------------
Changes in version 1.2 (29 Nov 2006)
- Added Solaris/Sparc port (basically some compiler define statements). Irrlicht and the examples should compile out-of-the-box on Suns with the usual Makefiles and gnumake.
- Added texture matrix support for hardware accelerated drivers. This allows for efficient texture coord manipulations for complete meshes at once.
- Multisampling with OpenGL under Linux added
- Non-power-of-two textures are left unscaled if the driver supports such textures.
- new draw2DImage method that speeds up drawing many quads from the same texture. Font drawing is improved by this under OpenGL.
- TGA files are now always correctly flipped and loaded if compressed. All PNG color formats are now supported, including correct alpha handling.
- 3ds mesh loader fix in texture loading, now loads some textures that were not loaded before, but might introduce problems with very recent files. OGRE mesh loader bugfixes and lightmap support. Several B3d mesh loader updates. Obj and mtl loader enhancements.
- A new compile flag (IRR_OPENGL_USE_EXTPOINTER) allows Irrlicht to either use OpenGL extension function pointers or direct OpenGL calls.
- OpenGL now uses frame buffer objects for render targets larger than the screen, supplied by Mandrav
- Split ESNRP_LIGHT_AND_CAMERA passes into ESNRP_LIGHT and ESNRP_CAMERA to fix a problem with lights being rendered before cameras in OpenGL (thanks again to Vitek for finding this). ESNRP_LIGHT_AND_CAMERA is now deprecated.
- Fixed many OpenGL render state problems which were related to wrong texture states. The textures are now enabled and disabled by the material renderers in OnSetMaterial. Also enabled the texture state cache which helps preventing texture changes just as the one for D3Dx. Thanks to hey_i_am_real for some good hints on where the problem was located.
- Added compile flag _IRR_COMPILE_WITH_X11_ which is by default enabled. Disabling the flag removes all X11 dependencies from Irrlicht and allows for a headless Linux Irrlicht server - added by request :-)
- Win32 OpenGL driver tries to use the requested bpp size.
- Default texture format is now A8R8G8B8 if not explicitly specified. This fixes some color artifacts with lightmaps. Bugfix submitted by hey_i_am_real.
- In OnPostRender all transformations were taken as relative and multiplied with the root transformation matrix every time due to a wrong check for the real root node. This shoudl increase render performance for scenes with lots of (invisible) nodes.
- GUIStatic text is correctly grayed out if disabled.
- Added getHeight method for terrain node submitted by Spintz. It calculates the height from the base mesh instead of requiring ray casts and collision detection and is much faster.
- New methods core::lerp to linearly interpolate two floats and SColor.getLuminance to calculate luminance of RGB color.
- MAJOR API CHANGE:
Fixed matrix access methods mat(x,y). These were previously said to be (row,column) but actually were (column, row). This lead to some confusion and made their use quite tricky. Irrlicht code is updated for the new method, but applications will silently fail now (i.e. compile without errors, but not working as expected).
- Update to zlib-1.2.3
- Fixed vertex alpha handling in DirectX drivers.
- Image writers fixed and working (at least for little endian systems).
- VSync under Linux fixed and correctly working.
- New os::Byteswap::byteswap methods which can be used for byteswapping (endianess correction) in mesh loaders and image loaders.
- New video driver feature to check for multitexture feature.
- Direct3D drivers update the devicelost variable if reseeting failed with this return code.
- VideoModeList under Linux is correctly filled now. No glX calls are made if GLX extension is not found - only software drivers are available then. RandR extension can be enabled with a new compile flag in IrrCompileConfig.h, either instead of XF86VidMode or in addition.
- Big Endian support for MS3D loader.
- Apfelbaum software renderer: basic mipmap support (per triangle), switch for using w-buffer instad z-buffer ( default on )
- Better FPU support: Changed various fpu-call's in whole project (main reason to use faster float to int conversion on x86. ( fistp ))
- changed Visual Studio 7.1 vcproj project config "Release Fast FPU" to __fastcall in /QIfist
- CGUIFont added True Alpha Font Support. (currently it's a little hack, but it'a good starting point. Fonts are back compatible. To use the new feature make first pixel half transparent in the font file.)
- Scolor: replaced s16 color with u16 color, replaced s32 color with u32 color to get rid of unnecessary arithmetic shift
other loaded meshes, and the #meshname workaround has been removed.
- File lists are now sorted.
- Dynamically checking the OpenGL version now instead of at compile time to call the supported methods of the executing machine, not that one of the compile host. This should fix the extension check and the automatic mipmap update.
- Fixed vertex alpha handling of 2D images with OpenGL.
- Default depth buffer under Windows now 24bit to avoid zbuffer fighting.
- Fixed light count in OpenGL.
- Particle emitters can now be enabled/disabled via a new method.
- Sky dome is rotatable just like the sky box.
- Rotation animator can be applied to several nodes now, before it only rotated the first one it was applied to.
- Support for drawing other vertex primitive lists such as triangle strips.
- Default specular color is white again, thus simply enabling shininess is enough to get speculars.
- Some .x loader and animator improvements. Vertex color support.
- isActive now also work under Linux.
-------------------------------------------
Changes in version 1.1 (06 Aug 2006)
- New example to show some features of the .irr format
- Added support for making screenshots in all video drivers and a general
possibility to save any IImage to several file formats.
Some image writers are not yet implemented. As a testcase screenshots
are now available in the demo by pressing F9.
This code was contributed by Travis Vitek.
- Changed EAMTS_OCT to EAMT_OCT.
- Improved .3ds and .obj file importers.
- Added support for .b3d (Blitz Basic) submitted by Luke Hoschke and
.pak (Quake archive) files submitted by skreamz.
- Added sky dome implementation contributed by Anders la Cour-Harbo (alc).
- In addition to the Cube scene node (formerly test scene node) there is now also a sphere scene node available,
with an adjustable amount of polygons. Use ISceneManager::addSphereSceneNode to create it.
Thx to Alfaz93 for making available his code on which this node is based on.
Note that both nodes now use default material settings, e.g. lighting is enabled by default.
- Fixed Linux keyhandling for many keys.
- The aspect ratio has been inverted in the matrix, which means when setting a new aspect ratio
for cameras, set it to screen.width/screen.height now instead of screen.height/screen.width
as previously.
- added support for reading/importing binary .x files.
- .ms3d and .x normals are now correctly transformed in animations, bounding
boxes are slightly better transformed, but not yet correct.
- Added possibility to load and save Irrlicht scenes to and from xml files via
ISceneManager::saveScene and ISceneManager::loadScene. Note that not all
scene nodes are supported yet, but most features should already work.
- Bounding box of the Skybox corrected (set to null)
- The SMaterial structure now supports 4 textures. (Currently ignored by the renderers and their materials.)
- Test scene node renamed to CubeSceneNode.
- Added scene node animator factories. This is the same as scene node
factories, but for scene node animators.
- Added scene node factories. This is an interface making it possible to dynamicly
create scene nodes. To be able to add custom scene nodes to Irrlicht and
to make it possible for the scene manager to save and load those external scene nodes, simply
implement this interface and register it in you scene manager via ISceneManager::
registerSceneNodeFactory
- Introduced IMeshSceneNode interface with the possibility to set readonly materials to make
it possible to use the mesh materials directly instead of overriding them. In this way
it is possible to change the materials of a mesh causing all mesh scene nodes
referencing this mesh to change, too.
- Added possibility to load OGRE .mesh files directly, thanks to Christian Stehno who contributed
a loader for this.
- Merged with Irrlicht 1.0 for MacOS
- Added a method getType() to ISceneNodeAnimator.
- There is now a system to serialize and deserialize attributes of scene nodes. In this way
it should be quite simple to to expose the attributes of your scene node for scripting
languages, editors, debuggers or xml serialization purposes.
- Irrlicht containers and strings now have allocators, making it possible to
use them across .dll boundaries.
- Changed the name of scene nodes from wide character to to char* for speed and memory reasons.
- Renamed IStringParameter class to IAttributes and enhanced it to be able to
serialize its content into and from xml.
- Textures now have a method getName().
- Added the methods getTextureCount() and getTextureByIndex() to IVideoDriver.
- Most classes now derive virtually from IUnknown.
-------------------------------------------
Changes in version 1.0 (19 Apr 2006)
- Irrlicht now will load d3d 9 dlls (like d3dx9_27.dll) manually if needed. If you compile irrlicht
with an SDK which needs one of these dlls, irrlicht will now also start up on a pc without
these Dlls installed. Note that now these dlls will also only be loaded if your application
uses shaders. If the dlls are missing, shader support will be disabled.
- The Apfelbaum Software Software Renderer now works in 32 bit and is capable of rendering dynamic
lighting as well as doing alpha channel blending.
- Added support for the Code::Blocks IDE (http://www.codeblocks.org)
- It is now possible to draw temporarily to foreign windows, by specifying a window handle when
calling IVideoDriver::endScene(). Note: This does not work in fullscreen mode and is not
