Export the result of Photo-SLAM Examples with Real Cameras

[Tanfuchy]

I can build the map in real time by using realsense provided by you, but I don't know how to save this result, such as exporting it as ply file. Thank you.

If the imgui viewer is available, just close the viewer and the results are automatically saved. Otherwise you might need to manually add some save points by changing GaussianMapper::savePly to a public member and calling it in the while (!pSLAM->isShutDown()) main loop.

如果 imgui 查看器可用，只需关闭查看器，结果就会自动保存。否则，您可能需要通过更改GaussianMapper::savePly为公共成员并在while (!pSLAM->isShutDown())主循环中调用它来手动添加一些保存点。

你好，我应该是正确使用了您提供的D455相机使用到该项目，但是在结果文件中发现只有used_times文件夹、没有ply文件。我应该怎么保存ply文件
