# 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);
```
