# RHIDevice::CreateSampler
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
virtual RHISampler* CreateSampler(const SamplerDesc& desc) = 0;
|
||
|
|
```
|
||
|
|
|
||
|
|
创建纹理采样器。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `desc` - 采样器描述符，包含过滤模式、寻址模式等
|
||
|
|
|
||
|
|
**返回：** 新创建的采样器指针，失败返回 `nullptr`
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
SamplerDesc samplerDesc;
|
||
|
|
samplerDesc.filter = (uint32_t)FilterMode::Anisotropic;
|
||
|
|
samplerDesc.addressU = (uint32_t)TextureAddressMode::Wrap;
|
||
|
|
samplerDesc.addressV = (uint32_t)TextureAddressMode::Wrap;
|
||
|
|
samplerDesc.addressW = (uint32_t)TextureAddressMode::Wrap;
|
||
|
|
samplerDesc.maxAnisotropy = 16;
|
||
|
|
samplerDesc.minLod = 0;
|
||
|
|
samplerDesc.maxLod = FLT_MAX;
|
||
|
|
|
||
|
|
RHISampler* sampler = device->CreateSampler(samplerDesc);
|
||
|
|
```
