Clipping a mesh to an isosurface

[stla]

Hello,

In the R package rgl, there is a function to clip a 3d mesh to a surface defined by f(x,y,z) > 0 where f is a given function. For example I've just done this tennis ball with this feature (I clipped the sphere two times, with f and with -f):

So we can achieve the same result with CGAL by using PMP::clip if we have a mesh of f(x,y,z)>0. It seems to me that the way used by rgl is more direct and more efficient. Maybe you would like to add this feature to CGAL? This is not complicated.

Do you mean something like #5895?

Hmm that's possible, I didn't understand everything yet. Is the bunny splitted in several pieces here?:

What I mean is really equivalent to PMP::clip(sphereMesh, isoMesh).
