|
|
设置颜色混合状态。控制源颜色和目标颜色如何混合，影响最终输出像素的颜色值。
|
|
|
|
**参数：**
|
|
- `state` - 混合状态结构体（包含 alphaToCoverageEnable、independentBlendEnable、renderTargets[] 等）
|
|
|
|
**返回：** `void`
|
|
|
|
**异常：** 无
|
|
|
|
**线程安全：** ❌

|
|
```cpp
|
|
BlendState blendState;
|
|
blendState.alphaToCoverageEnable = false;
|
|
blendState.independentBlendEnable = false;
|
|
blendState.renderTargets[0].blendEnable = true;
|
|
blendState.renderTargets[0].srcBlend = BlendFactor::SrcAlpha;
|
|
blendState.renderTargets[0].dstBlend = BlendFactor::InvSrcAlpha;
|
|
blendState.renderTargets[0].blendOp = BlendOp::Add;
