Incomplete Mesh about 2d-gaussian-splatting

[hbb1]

@JiajieLi7012 Thank you for your report. In order to export a mesh, it is necessary to have some prior information to determine the export location. When the center and radius are known, the 'depth_trunc' is set slightly larger than the radius. My code is designed to automatically estimate this based on the camera trajectory, assuming it follows a circular path. For indoor scenes, you can use information from the depth map to determine the 'depth_trunc', such as the maximum depth value.

I have the same problem, Have you solved this problem

[hbb1]

What is the depth_trunc then? My depth range is estimated using the camera traj. If you camera traj is not circular, there may be a problem.

[JiajieLi7012]

Thanks for your response. The depth_trunc is 22.29. The camera traj is not circular as shown in the image below.

Hi @ansj11, it looks like this is related to the depth_truc value. I tried to increase the depth_truc value from around 22 to 40 in this scene and got much better results as below. But I still don't know how to mitigate the problem systematically and I hope @hbb1 could share more insights later when he is available.
