## 概述
|
|||
|
|
|
|||
|
|
RenderDocCapture 是 RenderDoc 图形调试器的集成类,提供程序化帧捕获功能。通过 LoadRenderDoc API,可以触发帧捕获、获取捕获信息、设置捕获选项等。
|
|||
|
|
|
|||
|
|
该类为单例模式,通过 `Get()` 获取实例。支持设置捕获文件路径、捕获注释、捕获选项等。

## 使用示例
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
#include <XCEngine/Debug/RenderDocCapture.h>
|
|||
|
|
|
|||
|
|
using namespace XCEngine::Debug;
|
|||
|
|
|
|||
|
|
// 获取单例实例
|
|||
|
|
RenderDocCapture& renderDoc = RenderDocCapture::Get();
|
|||
|
|
|
|||
|
|
// 初始化(传入设备和窗口)
|
|||
|
|
renderDoc.Initialize(devicePtr, windowHandle);
|
|||
|
|
|
|||
|
|
// 设置捕获文件路径
|
|||
|
|
renderDoc.SetCaptureFilePath("captures/frame_%04i.cap");
|
|||
|
|
renderDoc.SetCaptureComments("Test capture - stress scene");
|
|||
|
|
|
|||
|
|
// 开始捕获
|
|||
|
|
renderDoc.BeginCapture("Main Window");
|
|||
|
|
|
|||
|
|
// ... 渲染代码 ...
|
|||
|
|
|
|||
|
|
// 结束捕获
|
|||
|
|
renderDoc.EndCapture();
|
|||
|
|
|
|||
|
|
// 或触发单帧捕获
|
|||
|
|
renderDoc.TriggerCapture();
|
|||
|
|
|
|||
|
|
// 检查捕获数量
|
|||
|
|
uint32_t numCaptures = renderDoc.GetNumCaptures();
|
|||
|
|
|
|||
|
|
// 启动回放界面
|
|||
|
|
renderDoc.LaunchReplayUI();
|
|||
|
|
```
