详细说明

AlphaCoverage 类型可启用阿尔法-覆盖多重采样模式。启用后，片段阿尔法值将被用作样本的覆盖值，并与片段覆盖值相结合。如果多重采样被禁用，AlphaCoverage 则不起任何作用。当需要与顺序无关的混合时，例如渲染树叶、草和其他丰富的植被时，Alpha-to-coverage 最有用。

它可以添加到RenderPass ：

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

或RenderStateSet ：

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