Problem Extracting Mesh Without 'use_centers_to_extract_mesh' Option

[josef5838]

Hi @Anttwo,

Thank you very much for the amazing work!

I am attempting an ablation experiment to extract the mesh directly from my 3DGS. While I successfully extracted the mesh using the use_centers_to_extract_mesh option, I encountered an issue when trying to extract it without this option (both foreground and background are empty).

The data I used includes the 3DGS and the camera parameters. I also tried manually setting up the bounding box, but this did not resolve the issue.

Could you please advise on what might be missing or provide any suggestions for troubleshooting this problem?

Thank you very much!
