Sliding Window and Reconstruction Time

[imlayman]

First of all, thank you for your work and contributions. I have four questions:

1. Did you use the method of sliding window to reconstruct the 3D scene by referring to other papers or by yourself?
2. I would like to know how to set the unit_size and query_vol_size parameters reasonably.
3. When I generated the 3D model on my data set, I found that the reconstruction time was not closely related to the number of point clouds, but was closely related to unit_size and query_vol_size. Why?
4. Can we only use sliding Windows to reconstruct large outdoor scenes? Because my reconstruction without sliding the window is weird.
