How to see the source code of geometric features?

[aaaxxx]

1.In Tools ->others -> compute geometric features, what's the difference between "roughness" and "surface variation"?
2.I want to know the source code of "compute geometric features", where do the cpp files locate?
Call for daniel, thank you!

Well, for most of the geometric features the code ends here: https://github.com/CloudCompare/CCCoreL ... s.cpp#L168
or here: https://github.com/CloudCompare/CCCoreL ... d.cpp#L760

The roughness is quite different from surface variation. It's described here: https://www.cloudcompare.org/doc/wiki/i ... /Roughness
