<h1>自定义混合方程常量（Custom Blending Equation Constants）</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，然后设置所需要的混合方程、源因子和目标因子。
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<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
|
||
|
|
</code>
|
||
|
|
|
||
|

<h2>混合方程</h2>
|
||
|
|
<code>
|
||
|
|
THREE.AddEquation
|
||
|
|
THREE.SubtractEquation
|
||
|
|
THREE.ReverseSubtractEquation
|
||
|
|
THREE.MinEquation
|

|
THREE.MaxEquation
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<h2>源因子</h2>
|
||
|
|
<code>
|
||
|
|
THREE.ZeroFactor
|
||
|
|
THREE.OneFactor
|
||
|
|
THREE.SrcColorFactor
|
||
|
|
THREE.OneMinusSrcColorFactor
|
||
|
|
THREE.SrcAlphaFactor
|
||
|
|
THREE.OneMinusSrcAlphaFactor
|
||
|
|
THREE.DstAlphaFactor
|
||
|
|
THREE.OneMinusDstAlphaFactor
|
||
|
|
THREE.DstColorFactor
|
||
|
|
THREE.OneMinusDstColorFactor
|
||
|
|
THREE.SrcAlphaSaturateFactor
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<h2>目标因子</h2>
|
||
|
|
<p>
|
||
|
|
所有的源因子的值，在目标因子中都是有效的。除了：<code>THREE.SrcAlphaSaturateFactor</code>
|
||
