Three Phase 3D Scanner

{{$t('general.by')}}
Technique from Song Zhang, coded in C++ by Alex Evans, ported to Processing by Florian Jennet. I rewrote the code and got rid of things that were unnecessary or didn't work. The original had a little less noise. I extrapolated out three variables instead of trying to compute them: zskew, zscale, and noiseTolerance.
