Detailed Description

The render state blend types for effect passes.

Enumeration Type Documentation

enum FUDaePassStateBlendType::Type
 

Enumerates the COLLADA render state blend types.

These are applied to either the destination or the source color.

The most common blend type is (SOURCE_ALPHA, ONE_MINUS_SOURCE_ALPHA) where the first blend type is applied on the source color and the second blend type is applied on the destination color to give the following equation: SrcColor * SrcAlpha + DestColor * (1.0 - SrcAlpha).

Enumerator:
ZERO  The color is not used.
ONE  The color is taken as is.
SOURCE_COLOR  The color is multiplied with the source color.
ONE_MINUS_SOURCE_COLOR  The color is multiplied with the inverse of the source color.
DESTINATION_COLOR  The color is multiplied with the destination color.
ONE_MINUS_DESTINATION_COLOR  The color is multiplied with the inverse of the destination color.
SOURCE_ALPHA  The color is multiplied with the source alpha.
ONE_MINUS_SOURCE_ALPHA  The color is multiplied with the inverse of the source alpha.
DESTINATION_ALPHA  The color is multiplied with the destination alpha.
ONE_MINUS_DESTINATION_ALPHA  The color is multiplied with the inverse of the destination alpha.
CONSTANT_COLOR  The color is multiplied with a constant color value.
ONE_MINUS_CONSTANT_COLOR  The color is multiplied with the inverse of a constant color value.
CONSTANT_ALPHA  The color is multiplied with a constant alpha value.
ONE_MINUS_CONSTANT_ALPHA  The color is multiplied with the inverse of a constant alpha value.
SOURCE_ALPHA_SATURATE  The color is multiplied with the saturation of the source alpha value.
INVALID  An invalid blend color type.
