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 {}
      ]
  }
