Question about curvature.cpp class about libigl HOT 2 CLOSED

I believe Daniele wrote this specific example. However, looking at it, it seems broken or at least out of date. I recommend following the API in libigl/include/igl/principal_curvature.h. The function takes in your mesh and computes 4 outputs: rows are respectively principal curvature directions and values at each vertex. See the documentation in the comments at the top of libigl/include/igl/principal_curvature.h.

You might have a look at the curvature directions example in the tutorial. Then have a look in libigl/tutorial/203_CurvatureDirections/main.cpp.

@danielepanozzo, we should fix (or maybe just remove) the libigl/examples/principal_curvature/ example. It does not use the API of libigl/include/igl/principal_curvature.h, instead secretly using classes inside libigl/include/igl/principal_curvature.cpp (as a side-effect it also will not work in the static lib).

Indeed, that example is outdated, I removed it from the repo. An example that uses the new API is in the tutorial: http://libigl.github.io/libigl/tutorial/tutorial.html#curvaturedirections
