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 {}
     ]
 }
