Expand description

Indicates which value to multiply each component with.

Variants§

§

Zero

Multiply the source or destination component by zero, which always gives 0.0.

§

One

Multiply the source or destination component by one, which always gives you the original value.

§

SourceColor

Multiply the source or destination component by its corresponding value in the source.

If you apply this to the source components, you get the values squared.

§

OneMinusSourceColor

Equivalent to 1 - SourceColor.

§

DestinationColor

Multiply the source or destination component by its corresponding value in the destination.

If you apply this to the destination components, you get the values squared.

§

OneMinusDestinationColor

Equivalent to 1 - DestinationColor.

§

SourceAlpha

Multiply the source or destination component by the alpha value of the source.

§

SourceAlphaSaturate

Multiply the source or destination component by the smallest value of SourceAlpha and 1 - DestinationAlpha.

§

OneMinusSourceAlpha

Multiply the source or destination component by 1.0 minus the alpha value of the source.

§

DestinationAlpha

Multiply the source or destination component by the alpha value of the destination.

§

OneMinusDestinationAlpha

Multiply the source or destination component by 1.0 minus the alpha value of the destination.

§

ConstantColor

Multiply the source or destination component by the corresponding value in Blend::const_value.

§

OneMinusConstantColor

Multiply the source or destination component by 1.0 minus the corresponding value in Blend::const_value.

§

ConstantAlpha

Multiply the source or destination component by the alpha value of Blend::const_value.

§

OneMinusConstantAlpha

Multiply the source or destination component by 1.0 minus the alpha value of Blend::const_value.

§

SourceOneColor

Multiply the source or destination component by its corresponding value in source index one (you need to explicitly specify layout(location=0, index=1) to bind it in your shader. This is useful in Dual Source Blending https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_blend_func_extended.txt

§

OneMinusSourceOneColor

Equivalent to 1 - SourceOneColor.

§

SourceOneAlpha

Multiply the source or destination component by the alpha value of source index 1.

§

OneMinusSourceOneAlpha

Multiply the source or destination component by 1.0 minus the alpha value of source index 1.
