Detailed Description

An AlphaCoverage type enables alpha-to-coverage multisampling mode. When enabled, the fragment alpha value is used as a coverage for the sample and combined with fragment coverage value. AlphaCoverage does nothing if multisampling is disabled. Alpha-to-coverage is most useful when order independent blending is required, for example when rendering leaves, grass and other rich vegetation.

It can be added to a RenderPass:

RenderPass {
    shaderProgram: ShaderProgram {
        // ...
    }
    renderStates: [
        AlphaCoverage {},
        MultiSampleAntiAliasing {}
    ]
}

Or to a RenderStateSet:

RenderStateSet {
    renderStates: [
        AlphaCoverage {},
        MultiSampleAntiAliasing {}
    ]
}
