- PixelBlend16 and PixelBlend16_simd are working for the new rules.
- bugfix. CLightSceneNode didn't correctly update it's attributes
Lighting Linear Attenuation. = 1.f / radius
The Example loadirr files set the lightscene radius to 1000.f but
stays on the previous default attentuation with the older radius 100 -> 1.f / 100
so the examples looks golden-brown.
Now the radius is correctly!! set to the attenuation of 1.f/1000.f because the
file doesn't have special attenuation. and now it looks more yellow.
can anybody show me a correct screenshot for this file;-)? Niko?
Or is this behavior the default lighting?. then it would be
a fixed constant linear attenuation of 0.01f;-). Please clearify
For now i didn't fixed it
I encountered this behavior because i ( burning video ) used the original radius
for calculations and so i've found that radius != 1.f / linearAttenuation but
in the LightSceneNode this formula was used.. confused;-)
- vector template and equals tests
as working with the test suits i cleaned the template behavior (mixed types are
used in the templates) and added all missing special math function with their coressponding type
I also set the equal test for s32 to behave like the f32 routine.
The function equals always implements a weak test.
that means a tolerance MUST always be used if you use the equal function. default is 1.
you can set it to zero a==b-> equals ( a, b, 0 ) but do it explicit like you have to
for floating compare. This is important when irrlicht is going to use special hardware
math acceleration on a per function base, like sse2, or the other way round fixpoint.
- VideoDriver drawPixel
The HW renderes are using the alpha components for blending.
The Software Renderes and image loaders are using CImage::setPixel copy.
so setPixel is engaged to either blends or copy the pixel
default: false
- Burningvideo
added RenderMaterial EMT_SPHERE_MAP
pushed burningsvideo to 0.43
added RenderMaterial EMT_REFLECTION_2_LAYER
pushed burningsvideo to 0.44
set EMT_TRANSPARENT_ALPHA_CHANNEL_REF
to use AlphaRef 0.5 like Direct3D
One Note: in OpenGL there is know difference between sphere_map and reflection layer
both using GL_TEXTURE_GEN_MODE GL_SPHERE_MAP, whereas in d3d one time using camera_normal
on sphere and reflection on refletcion_layer.
The visual difference is that on sphere map the "image is not moving" when you rotate the
viewer. For Buring i took the opengl visual. always moving
- rename quake3 SEntity to IEntity to be confom with IShader
even IShader and IEntity are none pure virtual interfaces
like most irrlicht objects
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@2207 dfc29bdd-3216-0410-991c-e03cc46cb475
Add IFileSystem::createMemoryWriteFile() to allow writing to memory.
Replace CMemoryReadFile with CMemoryFile that also implement IWriteFile.
Add an IVideoDriver::writeImageToFile() overload that takes an IWriteFile.
This allows writing (e.g.) screenshots to memory, rather than directly to file.
New unit test added to test the new functionality. Tested on Windows with VS2005 and C::B. I'll do Linux ASAP.
