enumerator Zero: Material Texture ChannelMapping.

enumerator One: Material Texture ChannelMapping.

enumerator Luminance: Material Texture ChannelMapping.

enum Decimation

Enumeration of the various decimation filters for textures. These are used when the texture needs to minimized.

Values:

enumerator None: No down-sampling will be performed. Data will be retrieved via the specified Texture::Interpolation filter.

enumerator Anisotropic: The texture will be down-sampled to non-square image sizes which will get used for sampling and filtering based on the angle between the normal of a textured surface and the view vector.

enumerator Mipmap: The texture will be down-sampled to square, power-of-two-sized images which will get used for sampling and filtering.

enum Interpolation

Enumeration of the various interpolation filters for textures. These are used when the texture needs to be magnified.

Values:

enumerator None: The texture coordinate will map to the closest texture samples.

enumerator Bilinear: The texture data from the four closest texture samples to a texture coordinate will be blended via a weighted average.

enum Parameterization

Enumeration of the parameterization sources for textures.

Values:

enumerator Cylinder: Use a cylindrical mapping for the texture.

enumerator PhysicalReflection: Texture Parameterization.

enumerator Object: Use the (x,y,z) coordinates for the object before transforms have been applied for the texture parameters.

enumerator NaturalUV: Use the natural mapping for meshes, NURBS surfaces and shells for the texture. For meshes, textures will be stretched in the range [0,1]. For NURBS surfaces, textures will be mapped in the range [0,(control point count - degree)]. For shells, textures will be mapped such that u=x+z and v=x+y where (x,y,z) is in object space.

enumerator ReflectionVector: Texture Parameterization.

enumerator SurfaceNormal: Texture Parameterization.

enumerator Sphere: Use a spherical mapping for the texture.

enumerator UV: Use the mapping explicitly defined on the geometry for the texture.

enumerator World: Use the (x, y, z) coordinates for the object after transforms have been applied for the texture parameters.

enum Tiling

Enumeration of the tiling modes for textures.

Values:

enumerator Clamp: The texture will get mapped normally for parameters in the range [0,1], but parameters less than 0 will be clamped to 0 and parameters greater than 1 will be clamped to 1.

enumerator Repeat: The texture will get mapped repeatedly in a modulo fashion.

enumerator Reflect: The texture will get mapped repeatedly in a modulo fashion. Every other modulo will also be inverted.

enumerator Trim: The texture will get mapped normally for parameters in the range [0,1], but parameters outside that range will act as if the texture at that location is transparent.
