I've been evaluating geometry and texture quality for clients, comparing Scanner app v.s Room Capture app v.s. Skanect Pro v.s. itSeez. I was able to tweak the volume resolution higher in both the Scanner and Room Capture sample apps, but eventually a computation limit was reached (using the original iPad Air), after which the geometry started falling apart. For the Scanner app, which does per vertex coloring, not texture mapping, the image density improved along with the geometry. For the Room Capture app the mesh density improved. I didn't spend much time on the texture when tweaking the Room Capture sample since the geometry resolution still wasn't high enough for the application. My hope is that the new iPad Air will support higher volume resolution.
I recall you mentioned doing a lot of Pre-viz for Interior Design applications. Is Texture quality the most important factor for your application? Precise alignment at the beginning and end of a full room scan?
It sounds like your results using Skanect Pro are achieving the highest quality results of all the Occipital software offerings. Does the latency issue you mentioned prevent that approach from being a viable working solution for you?
