# D3D12Device::CreateSampler
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
RHISampler* CreateSampler(const SamplerDesc& desc) override;
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
**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);
|
||
|
|
```
