|
|
|
|||
|
|
```cpp
|
|||
|
|
void Initialize(ID3D12Device* device, ID3D12Resource* resource, const D3D12_SHADER_RESOURCE_VIEW_DESC* desc = nullptr)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 描述
|
|||
|
|
|
|||
|
|

|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
// 创建 SRV，使用默认描述符
|
|||
|
|
D3D12ShaderResourceView srv;
|
|||
|
|
srv.Initialize(device, texture, nullptr);
|
|||
|
|
|
|||
|
|
// 创建 SRV，使用自定义描述符
|
|||
|
|
D3D12_SHADER_RESOURCE_VIEW_DESC desc = D3D12ShaderResourceView::CreateDesc(Format::R8G8B8A8_UNorm);
|
|||
|
|
srv.Initialize(device, texture, &desc);
