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

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。

代码示例


		const 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

例子

[example:webgl_materials_blending_custom materials / blending / custom ]

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
