Algorithm or software for slicing a mesh

Question

What is the right approach for slicing a 3D mesh? The mesh are all closed surfaces and the slices need to be binary images of what\'s inside the mesh. So for example, a mesh rep

Answer 1

It would be faster (for yourself, not running-time) if you implement it yourself: These are the simple steps you need to do:

1-Extract all the triangles of the mesh

2-For each triangle,

2-1- check if any of triangle points are on the slice-plane,

2-2- if not, then for each of its three edges, find the intersection with your slice-plane (if there is any). You must either have 2 of them intersected with the plane or none.

2-2-1 If 2 edges intersected with the plane, then you add a line between these 2 points on the plane.
