EMT_SOLID = 0,
|
|
|

|

//! This material is currently not implemented in OpenGL, but it
|
|
//! works with DirectX.
|
|
EMT_SOLID_2_LAYER,
|
|
|
|
//! Material type with standard lightmap technique:
|
|
//! There should be 2 textures: The first texture layer is a diffuse map,
|
|
//! the second is a light map. Vertex light is ignored.
|
|
EMT_LIGHTMAP,
|
|
|
|
//! Material type with lightmap technique like EMT_LIGHTMAP, but
|
|
//! lightmap and diffuse texture are not modulated, but added instead.
|
|
EMT_LIGHTMAP_ADD,
|
|
|
|
//! Material type with standard lightmap technique:
|
|
//! There should be 2 textures: The first texture layer is a diffuse map,
|
|
//! the second is a light map. Vertex light is ignored.
|
|
//! The texture colors are effectively multiplyied by 2 for brightening.
|
|
//! like known in DirectX as D3DTOP_MODULATE2X.

//! Material type with standard lightmap technique:
|
|
//! There should be 2 textures: The first texture layer is a diffuse map,
|
|
//! the second is a light map. Vertex light is ignored.
|
|
//! The texture colors are effectively multiplyied by 4 for brightening.
|
|
//! like known in DirectX as D3DTOP_MODULATE4X.
|
|
EMT_LIGHTMAP_M4,
|
|
|
|
//! Like EMT_LIGHTMAP, but also supports dynamic lighting.
|

EMT_LIGHTMAP_LIGHTING,
|
|
|
|

|
|
EMT_LIGHTMAP_LIGHTING_M2,
|
|
|
|
//! Like EMT_LIGHTMAP_4, but also supports dynamic lighting.
|
|
EMT_LIGHTMAP_LIGHTING_M4,
|
|
|
|
//! Detail mapped material. The first texture is diffuse color map, the
|
|
//! second is added to this and usually displayed with a bigger scale value
|
|
//! so that it adds more detail. The detail map is added to the diffuse map using
|
|
//! ADD_SIGNED, so that it is possible to add and substract color from the diffuse
|
|
//! map. For example a value of (127,127,127) will not change the appearance of
|
|
//! the diffuse map at all.
|
|
//! Often used for terrain rendering.
|
|
EMT_DETAIL_MAP,
|
|
|
|
//! Makes the material look like it was reflection the environment
|
|
//! around it. To make this possible, a texture called 'sphere map'
|
|
//! is used, which must be set as Textures[0].
|
|
EMT_SPHERE_MAP,
|
|
|
|
//! A reflecting material with an
|
|
//! optional additional non reflecting texture layer. The reflection
|
|
//! map should be set as Texture 1.
|
|
EMT_REFLECTION_2_LAYER,
|
|
|
|
//! A transparent material. Only the first texture is used.
|
|
//! The new color is calculated by simply adding the source color and
|
|
//! the dest color. This means if for example a billboard using a texture with
|
|
//! black background and a red circle on it is drawn with this material, the
|
|
//! result is that only the red circle will be drawn a little bit transparent,
|
|
//! and everything which was black is 100% transparent and not visible.
|
|
//! This material type is useful for e.g. particle effects.
|
|
EMT_TRANSPARENT_ADD_COLOR,
|
|
|
|
//! Makes the material transparent based on the texture alpha channel.
|
|
//! The final color is blended together from the destination color and the
|
|
//! texture color, using the alpha channel value as blend factor.
|
|
//! Only first texture is used. If you are using this material with small
|
|
//! textures, it is a good idea to load the texture in 32 bit
|
|
//! mode (video::IVideoDriver::setTextureCreationFlag()).
|
|
//! Also, an alpha ref is used, which can be manipulated using SMaterial::MaterialTypeParam.
|
|
//! If set to 0, the alpha ref gets its default value which is 0.5f and which means
|
|
//! that pixels with an alpha value >127 will be written, others not. In other, simple
|
|
//! words: this value controls how sharp the edges become when going from a
|
|
//! transparent to a solid spot on the texture.
|
|
EMT_TRANSPARENT_ALPHA_CHANNEL,
|
|
|
|
//! Makes the material transparent based on the texture alpha channel.
|
|
//! If the alpha channel value is greater than 127, a pixel is written to the
|
|
//! target, otherwise not. This material does not use alpha blending
|
|
//! and is a lot faster than EMT_TRANSPARENT_ALPHA_CHANNEL. It
|
|
//! is ideal for drawing stuff like leafes of plants, because the borders
|
|
//! are not blurry but sharp.
|
|
//! Only first texture is used. If you are using this material with small
|
|
//! textures and 3d object, it is a good idea to load the texture in 32 bit
|
|
//! mode (video::IVideoDriver::setTextureCreationFlag()).
|
|
EMT_TRANSPARENT_ALPHA_CHANNEL_REF,
|
|
|
|
//! Makes the material transparent based on the vertex alpha value.
|
|
EMT_TRANSPARENT_VERTEX_ALPHA,
|
|
|
|
//! A transparent reflecting material with an
|
|
//! optional additional non reflecting texture layer. The reflection
|
|
//! map should be set as Texture 1. The transparency depends on the
|
|
//! alpha value in the vertex colors. A texture which will not reflect
|
|
//! can be set als Texture 2.
|
|
//! Please note that this material type is currently not 100% implemented
|
|
//! in OpenGL. It works in Direct3D.
|
|
EMT_TRANSPARENT_REFLECTION_2_LAYER,
|
|
|
|
//! A solid normal map renderer. First texture is the color map, the
|
|
//! second should be the normal map. Note that you should use this material
|
|
//! only when drawing geometry consisting of vertices of type S3DVertexTangents
|
|
//! (EVT_TANGENTS). You can convert any mesh into this format using
|
|
//! IMeshManipulator::createMeshWithTangents() (See SpecialFX2 Tutorial).
|
|
//! This shader runs on vertex shader 1.1 and pixel shader 1.1 capable hardware and
|
|
//! falls back on a fixed function lighted material if this hardware is not available.
|
|
//! Only two lights are supported by this shader, if there are more, the nearest two
|
|
//! are chosen. Currently, this shader is only implemented for the D3D8 and D3D9 renderers.
|
|
EMT_NORMAL_MAP_SOLID,
|
|
|
|
//! A transparent normal map renderer. First texture is the color map, the
|
|
//! second should be the normal map. Note that you should use this material
|
|
//! only when drawing geometry consisting of vertices of type S3DVertexTangents
|
|
//! (EVT_TANGENTS). You can convert any mesh into this format using
|
|
//! IMeshManipulator::createMeshWithTangents() (See SpecialFX2 Tutorial).
|
|
//! This shader runs on vertex shader 1.1 and pixel shader 1.1 capable hardware and
|

//! falls back on a fixed function lighted material if this hardware is not available.
|
|
//! Only two lights are supported by this shader, if there are more, the nearest two
|
|
//! are chosen. Currently, this shader is only implemented for the D3D8 and D3D9 renderers.
|
|
EMT_NORMAL_MAP_TRANSPARENT_ADD_COLOR,
|
|
|
|
//! A transparent (based on the vertex alpha value) normal map renderer.
|
|
//! First texture is the color map, the
|
|
//! second should be the normal map. Note that you should use this material
|
|
//! only when drawing geometry consisting of vertices of type S3DVertexTangents
|
|
//! (EVT_TANGENTS). You can convert any mesh into this format using
|
|
//! IMeshManipulator::createMeshWithTangents() (See SpecialFX2 Tutorial).
|
|
//! This shader runs on vertex shader 1.1 and pixel shader 1.1 capable hardware and
|
|
//! falls back on a fixed function lighted material if this hardware is not available.
|
|
//! Only two lights are supported by this shader, if there are more, the nearest two
|
|
//! are chosen. Currently, this shader is only implemented for the D3D8 and D3D9 renderers.
|
|
EMT_NORMAL_MAP_TRANSPARENT_VERTEX_ALPHA,
|
|
|
|
//! Just like EMT_NORMAL_MAP_SOLID, but uses parallax mapping too, which
|
|
//! looks a lot more realistic. This only works when the hardware supports at
|
|
//! least vertex shader 1.1 and pixel shader 1.4.
|
|
//! First texture is the color map, the second should be the normal map.
|
|
//! The normal map texture should contain the height value in the
|
|
//! alpha component. The IVideoDriver::makeNormalMapTexture() method writes
|
|
//! this value automaticly when creating normal maps from a heightmap when using a 32 bit
|
|
//! texture.
|
|
//! The height scale of the material (affecting the bumpiness) is being controlled
|
|
//! by the SMaterial::MaterialTypeParam member.
|
|
//! If set to zero, the default value (0.02f) will be applied. Otherwise
|
|
//! the value set in SMaterial::MaterialTypeParam is taken. This value depends on with which
|
|
//! scale the texture is mapped on the material. Too high or low values of MaterialTypeParam
|
|
//! can result in strange artifacts.
|
|
EMT_PARALLAX_MAP_SOLID,
|
|
|
|
//! A material just like EMT_PARALLAX_MAP_SOLID, but it is transparent, using
|
|
//! EMT_TRANSPARENT_ADD_COLOR as base material.
|
|
EMT_PARALLAX_MAP_TRANSPARENT_ADD_COLOR,
|

|
|
//! A material just like EMT_PARALLAX_MAP_SOLID, but it is transparent, using
|

//! EMT_TRANSPARENT_VERTEX_ALPHA as base material.
|
|
EMT_PARALLAX_MAP_TRANSPARENT_VERTEX_ALPHA,
|
|
|
|
//! BlendFunc = source * sourceFactor + dest * destFactor ( E_BLEND_FUNC )
|
|
//! Using only Textures[0]. generic Blender
|
|
EMT_ONETEXTURE_BLEND,
|
|
|
|
//! This value is not used. It only forces this enumeration to compile in 32 bit.

EMT_FORCE_32BIT = 0x7fffffff
