自定义混合方程常量（Custom Blending Equation Constants）

示例

materials / blending / custom

用法

这个常量可以用于所有的材质类型。首先将材质的混合模式设置为THREE.CustomBlending，然后设置所需要的混合方程、源因子和目标因子。

var material = new THREE.MeshBasicMaterial( {color: 0x00ff00} ); 
material.blending = THREE.CustomBlending; 
material.blendEquation = THREE.AddEquation; //default 
material.blendSrc = THREE.SrcAlphaFactor; //default 
material.blendDst = THREE.OneMinusSrcAlphaFactor; //default

混合方程

THREE.AddEquation THREE.SubtractEquation THREE.ReverseSubtractEquation THREE.MinEquation THREE.MaxEquation

源因子

THREE.ZeroFactor THREE.OneFactor THREE.SrcColorFactor THREE.OneMinusSrcColorFactor THREE.SrcAlphaFactor THREE.OneMinusSrcAlphaFactor THREE.DstAlphaFactor THREE.OneMinusDstAlphaFactor THREE.DstColorFactor THREE.OneMinusDstColorFactor THREE.SrcAlphaSaturateFactor

目标因子

所有的源因子的值，在目标因子中都是有效的。除了：THREE.SrcAlphaSaturateFactor
