< h1 > 自定义混合方程常量（ ） < / h1 >
< p >
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，

< h2 > 代码示例< / h2 >
< code >
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
