Enable alpha-to-coverage multisampling mode. More...

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 {} ] }
