# D3D12Device::CreateSampler

```cpp
RHISampler* CreateSampler(const SamplerDesc& desc) override;
```

创建 D3D12 采样器。

**参数：**
- `desc` - 采样器描述符，包含过滤模式、地址模式等

**返回：** 新创建的采样器指针，失败返回 `nullptr`

**示例：**

```cpp
SamplerDesc samplerDesc;
samplerDesc.filter = (uint32_t)D3D12_FILTER_MIN_MAG_MIP_LINEAR;
samplerDesc.addressU = (uint32_t)D3D12_TEXTURE_ADDRESS_MODE_WRAP;
samplerDesc.addressV = (uint32_t)D3D12_TEXTURE_ADDRESS_MODE_WRAP;
samplerDesc.addressW = (uint32_t)D3D12_TEXTURE_ADDRESS_MODE_WRAP;

RHISampler* sampler = device->CreateSampler(samplerDesc);
```
