Hi F360Fellows,
As promised, please find some visuals of the Flattening Surfaces Approach. In the general case, the process is not trivial and dependent upon the breadth/scope of its development might vary. The visuals demonstrates some aspect of attacking the problem. Obviously, the march/battle to … final resolution is arduous. So who knows where the road will wander?
A short explanation of some histograms symbols:
- ΔA – flattened surface local relative area size error
- ΔP – flattened surface local relative perimeter length error
- ΔD – flattened surface local maximum length distortion along UV axes

To be viewed on 4K media devices (monitors, UHD TVs, projectors...) of reasonable performance. For the best experience, use stand-alone media applications (WMP, VLC) and the native resolution 3840x2160 - full screen. The '_arcd' files require an anaglyph red/cyan glasses, while '_al' is for active shutter glasses 3D hardware (~30 deg viewing angle is recommended). Download the files over a network, where the cost of doing so is not a concern. The files are to be used for private, non-commercial purposes only.
