Thanks for the feedback. I was expecting to have this weekend to pull everything together but Apple approved the app in 2 days (which is great, but 5x faster than for my previous submissions).
The first question that comes to mind for me is: Is it possible to export the generated mesh that is shown in the stills?
Good question. Version 1.0 only saves/emails images, but trading 3D scans and exporting the raw mesh is certainly on the feature list for future versions.
Might I suggest using the Bump API to share scans?
Please add .obj export. That format is easy, free and widely supported.
