pub enum BlendEquation {
    FuncAdd,
    FuncSubstract,
    FuncReverseSubtract,
}
Expand description

Constants passed to WebGLRenderingContext.blendEquation() or WebGLRenderingContext.blendEquationSeparate() to control how the blending is calculated (for both, RBG and alpha, or separately).

Variants

FuncAdd

Passed to blendEquation or blendEquationSeparate to set an addition blend function.

FuncSubstract

Passed to blendEquation or blendEquationSeparate to specify a subtraction blend function (source - destination).

FuncReverseSubtract

Passed to blendEquation or blendEquationSeparate to specify a reverse subtraction blend function (destination - source).
