As a non-scientific exercise in qualitative comparison, I’ve assembled here some 3D models made in different photogrammetry programs (VisualSFM, ReCap 360, PhotoScan) from the same source photos. Hopefully this illustrates both the different (and similar) kinds of reconstructions you get with different programs, as well as showing “more faces != better than.” The PhotoScan reconstructions for example are done on “Medium” quality settings in order to speed up processing, and higher face count models could probably be reconstructed there (without much more real increase in “quality” depending on the intended application). Presumably merging together the output of different programs could allow some visualizations of the differences in reconstruction, or yield a better combined model in some instances.
