Hi, I have been trying to run the online reconstruction pipeline. As the TSDF volume is extended incrementally, I would like to keep the mesh at each integration step. However, by doing so, the usage of GPU keeps increasing and then OOM at some point.
The example integrate.py calls the mesh extraction function only once at the end of the program. Therefore this problem may have not been encountered by developers. Following is my extended code to reproduce this problem. One can simply run the code with the default dataset. Thus it is straightforward to reproduce. Appreciate it if anyone can help! Thanks!

Please consider using a larger voxel size (currently 0.00585938) for TSDF integration, or using tsdf_volume.cpu() to perform mesh extraction on CPU.
Expected behavior
Mesh is extracted successfully at each iteration, and the memory usage is not continuously increasing.
