Detailed Description

The Material::Texture class is a concept class for texture-related enum classes.

Member Enumeration Documentation

Channel

enum HPS::Material::Texture::Channel : uint32_t

strong

Material Texture Channel.

Enumerator
DiffuseTexture	Material Texture Channel.
Specular	Material Texture Channel.
Emission	Material Texture Channel.
Transmission	Material Texture Channel.
Mirror	Material Texture Channel.
Bump	Material Texture Channel.
EnvironmentTexture	Material Texture Channel.
EnvironmentCubeMap	Material Texture Channel.

ChannelMapping

enum HPS::Material::Texture::ChannelMapping : uint32_t

strong

Material Texture ChannelMapping.

Enumerator
Red	Material Texture ChannelMapping.
Green	Material Texture ChannelMapping.
Blue	Material Texture ChannelMapping.
Alpha	Material Texture ChannelMapping.
Zero	Material Texture ChannelMapping.
One	Material Texture ChannelMapping.
Luminance	Material Texture ChannelMapping.

Decimation

enum HPS::Material::Texture::Decimation : uint32_t

strong

Enumeration of the various decimation filters for textures.

These are used when the texture needs to minimized.

Enumerator
None	No down-sampling will be performed. Data will be retrieved via the specified Texture::Interpolation filter.
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.
Mipmap	The texture will be down-sampled to square, power-of-two-sized images which will get used for sampling and filtering.

Interpolation

enum HPS::Material::Texture::Interpolation : uint32_t

strong

Enumeration of the various interpolation filters for textures.

These are used when the texture needs to be magnified.

Enumerator
None	The texture coordinate will map to the closest texture samples.
Bilinear	The texture data from the four closest texture samples to a texture coordinate will be blended via a weighted average.

Parameterization

enum HPS::Material::Texture::Parameterization : uint32_t

strong

Enumeration of the parameterization sources for textures.

Enumerator
Cylinder	Use a cylindrical mapping for the texture.
PhysicalReflection	Texture Parameterization.
Object	Use the (x,y,z) coordinates for the object before transforms have been applied for the texture parameters.
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.
ReflectionVector	Texture Parameterization.
SurfaceNormal	Texture Parameterization.
Sphere	Use a spherical mapping for the texture.
UV	Use the mapping explicitly defined on the geometry for the texture.
World	Use the (x, y, z) coordinates for the object after transforms have been applied for the texture parameters.

Tiling

enum HPS::Material::Texture::Tiling : uint32_t

strong

Enumeration of the tiling modes for textures.

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