how to compute curvature

[Linycs]

Dear Authors:

I am trying to apply Lemon_3d on other datasets. Thus, I'm curious about how did you compute the curvature of both smpl mesh and object point clouds.

Thanks!

For smpl mesh, the simplest way is to use the trimesh API:

#for body 
curvature_mesh = trimesh.curvature.discrete_gaussian_curvature_measure(mesh, vertices, 0.12)[:,None].
#for hand
curvature_mesh = trimesh.curvature.discrete_mean_curvature_measure(mesh, vertices, 0.06)[:,None]

For object point clouds, the simplest way is to use software like CloudCompare.
