Defines how some color will be multiplied before being blended. The destination color is the color that is currently in the frame buffer, and the source color is the color that is produced by the fragment shader. See BlendFunc for more about how to use these.

Variants

Zero

The color is multiplied by zero, turning it black.

One

The color is multiplied by one, leaving it unchanged.

SrcColor

The color is multiplied by the source color.

OneMinusSrcColor

The color is multiplied by (1 - src), the inverted source color.

DstColor

The color is multiplied by the destination color.

OneMinusDstColor

The color is multiplied by (1 - dst), the inverted destination color.

SrcAlpha

The color is multiplied by the alpha of the source color.

OneMinusSrcAlpha

The color is multiplied by (1 - alpha), the inverted alpha of the source color.

DstAlpha

The color is multiplied by the alpha of the destination color.

OneMinusDstAlpha

The color is multiplied by (1 - alpha), the inverted alpha of the destination color.

ConstantColor

The color is multiplied by the blend constant.

OneMinusConstantColor

The color is multiplied by (1 - constant), the inverted blend constant.

ConstantAlpha

The color is multiplied by the alpha of the blend constant.

OneMinusConstantAlpha

The color is multiplied by (1 - alpha), the inverted alpha of the blend constant.

SrcAlphaSaturate

Red, green, and blue channels are multiplied by min(src alpha, 1 - dst alpha), and the alpha channel is multiplied by 1.

Src1Color

The color is multiplied by the color of the second source.

OneMinusSrc1Color

The color is multiplied by (1 - src1), the inverted color of the second source.

Src1Alpha

The color is multiplied by the alpha of the second source.

OneMinusSrc1Alpha

The color is multiplied by (1 - alpha), the inverted alpha of the second source.
