Detailed Description

Contains classes, functions and enums related to rendering.

See also the OpenMayaRender - API module for rendering module.

Enumeration Type Documentation

anonymous enum

Indicates the geometry options for polygon.

Enumerator
kPolyGeom_Normal	Normal Indicates the polygon performs the default geometry.
kPolyGeom_NotSharing	NotSharing Indicates if you don't want vertex sharing to be computed by the extractor. Vertex buffer size will not be reduced if sharing can be performed.
kPolyGeom_BaseMesh	BaseMesh Indicates if you want the base geometry in smoothCage mode. The geometry in extractor is always the base geometry in normal mode.

Pixel / raster formats.

The following short form notation is used for channel specification:

• R = red channel
• G = green channel
• B = blue channel
• A = alpha channel
• E = exponent channel
• L = luminence channel
• X = channel is not used
• DXT1, DXT2, DXT3, DXT4, and DXT5 are S3 compression formats
• BC6H, BC7 are extended compression formats only for DirectX 11
• Numbers after the channel gives the bit depth
• Channel order is data storage order.

The following short form notation is used for data format specification:

• UNORM means unsigned values which have been normalized to the 0 to 1 range.
• SNORM means signed values which have been normalized to the -1 to 1 range.
• UINT means unsigned integer values
• SINT means signed integer values
• FLOAT means floating point
• If normalization is not explicitly specified then the values are unnormalized
