Hi,
The "Organized Online Meshing" will create a mesh for each frame. It will be similar to RTAB-Map Tango rendering:
https://www.youtube.com/watch?v=FvhxdUhsNUkTo get an optimized mesh, we should do File-> Export 3D clouds (or Edit->View point clouds...), then click on Meshing option.
cheers,
Mathieu
