详细说明

AlphaCoverage 类型可启用“透明度转覆盖率”多采样模式。启用后，片段透明度值将作为采样的覆盖率，并与片段覆盖率值相结合。如果禁用了多采样，AlphaCoverage 将不执行任何操作。当需要顺序无关混合时，“透明度转覆盖率”最为有用，例如在渲染树叶、草丛和其他茂密的植被时。

可将其添加到RenderPass 中：

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

或添加到RenderStateSet 中：

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

另请参阅 MultiSampleAntiAliasing 。
