## 头文件
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
#include <XCEngine/RHI/D3D12/D3D12DepthStencilView.h>
|
|||
|
|
```
|

### 构造函数与析构函数
|
|||
|
|
|
|||
|
|
#### `D3D12DepthStencilView()`
|
|||
|
|
默认构造函数。
|
|||
|
|
|
|||
|
|
#### `~D3D12DepthStencilView()`
|
|||
|
|
析构函数，确保调用 `Shutdown()`。
|
|||
|
|
|
|||
|
|
### 初始化
|
|||
|
|
|
|||
|
|
#### `void Initialize(ID3D12Device* device, ID3D12Resource* resource, const D3D12_DEPTH_STENCIL_VIEW_DESC* desc = nullptr)`
|
|||
|
|
创建 DSV。
|
|||
|
|
|
|||
|
|
#### `void InitializeAt(ID3D12Device* device, ID3D12Resource* resource, D3D12_CPU_DESCRIPTOR_HANDLE handle, const D3D12_DEPTH_STENCIL_VIEW_DESC* desc = nullptr)`
|
|||
|
|
在指定位置创建 DSV。
|
|||
|
|
|
|||
|
|
#### `void Shutdown()`
|
|||
|
|
释放 DSV。
|
|||
|
|
|
|||
|
|
### 属性
|
|||
|
|
|
|||
|
|
#### `D3D12_CPU_DESCRIPTOR_HANDLE GetCPUDescriptorHandle() const`
|
|||
|
|
获取 CPU 描述符句柄。
|
|||
|
|
|
|||
|
|
### 静态辅助函数
|
|||
|
|
|
|||
|
|
#### `static D3D12_DEPTH_STENCIL_VIEW_DESC CreateDesc(Format format, D3D12_DSV_DIMENSION dimension = D3D12_DSV_DIMENSION_TEXTURE2D)`
|
|||
|
|
创建 DSV 描述。
|
|||
|
|
|
|||
|
|
## 内部成员
|
|||
|
|
|
|||
|
|
| 成员 | 类型 | 描述 |
|
|||
|
|
|------|------|------|
|
|||
|
|
| `m_handle` | `D3D12_CPU_DESCRIPTOR_HANDLE` | CPU 描述符句柄 |
|
|||
|
|
| `m_resource` | `ID3D12Resource*` | 关联的资源 |
|
|||
|
|
|
|||
|
|
## 备注
|
|||
|
|
|
|||
|
|
- DSV 必须在 DSV 类型描述符堆中分配
|
|||
|
|
- 支持只读 DSV（通过描述符标志区分）
