Dear @Ed Beck , share, if not a secret how much this software package Pix4D (Month / Year's Day $).
-What using alternative software.
-How does 3D work solo with geotagging.
-How to work with GoPro.
-You used tower Ar.
-What largest object was processed, how long are processing.
-In depending on the area or volume processing, the processing time depends largely.
What used overlapping strips shooting% than the difference in quality 3d models in practice, if, for example, the cathedral, or will it be a pond in the beam.

Now, 3D-scanning offers building 3d models using AutoCad tsyvyl. I wait much money they make.
In this case, it translyt translated from Big Brother (Google)
I use sidelap and overlap of 80% for each. I've never tried to create a 3D image of a cathedral or any other building. The only 3D models I've made were because I did a survey and wanted to see what it would look like in 3D.
