TSDF Integration vs RGBD integration

[navid-mahmoudian]

Hello,

Thank you very much for providing this very interesting library. I noticed that to fuse RGB-D images Open3D has 2 different tutorials: one for TSDF Integration and one for RGBD integration. I can see that in RGBD integration, TSDF volume integration is used via ScalableTSDFVolume. However, in TSDF integration it seems that Voxel Block Grid is used. Are they using the similar thing? Is there any difference between these two in terms of accuracy vs performance? For example, can I say that TSDF Integration is for fast/online 3D reconstruction application and RGBD integration is for offline/more accurate 3D reconstruction?
