# D3D12SwapChain::Initialize
|
||
|
|
|
||
|
|
初始化 D3D12SwapChain 交换链。
|
||
|
|
|
||
|
|
## 重载 1: 从头创建
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
bool Initialize(IDXGIFactory4* factory, ID3D12CommandQueue* commandQueue, HWND windowHandle, uint32_t width, uint32_t height, uint32_t bufferCount = 2);
|
||
|
|
```
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `factory` - DXGI 工厂指针
|
||
|
|
- `commandQueue` - 命令队列指针
|
||
|
|
- `windowHandle` - 窗口句柄
|
||
|
|
- `width` - 宽度
|
||
|
|
- `height` - 高度
|
||
|
|
- `bufferCount` - 缓冲数量，默认为 2
|
||
|
|
|
||
|
|
**返回：** `bool` - 初始化成功返回 true
|
||
|
|
|
||
|
|
## 重载 2: 从现有交换链创建
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
bool Initialize(IDXGISwapChain* swapChain, uint32_t width, uint32_t height);
|
||
|
|
```
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `swapChain` - 现有 DXGI 交换链指针
|
||
|
|
- `width` - 宽度
|
||
|
|
- `height` - 高度
|
||
|
|
|
||
|
|
**返回：** `bool` - 初始化成功返回 true
