bool alphaToCoverageEnable

Search for all occurrences

Enable alpha to coverage.

Default false.

bool independentBlendEnable

Search for all occurrences

Use TargetBlends[0] if false or individual blend states if true.

Default false.

Examples:

hwColorPerVertexShader.cpp, and hwPhongShader.cpp.

float blendFactor[4]

Search for all occurrences

Global blend factor, default (1,1,1,1).

Examples:

hwColorPerVertexShader.cpp, and hwPhongShader.cpp.

unsigned int multiSampleMask

Search for all occurrences

Each bit in this mask, starting at the least significant bit (LSB), controls modification of one of the samples in a multisample render target.

Thus, for an 8-sample render target, the low byte contains the eight write enables for each of the eight samples. The actual location of the samples is determined by the GPU sample pattern, which is not in general known or controlled directly by applications. Default 0xffffffff.

MTargetBlendDesc targetBlends[MBlendState::kMaxTargets]

An array of 8 MTargetBlendDesc, one for each target.

Examples:

hwColorPerVertexShader.cpp, and hwPhongShader.cpp.
