Thank you very much for this. It is really appreciated. Will try all of these and will let you know if any problem occurred then. Thanks again to all.

This should get you started to read a PLY file into a Polyhedron using
RPly [1] and CGAL::Incremental_builder_3 [2]

It requires ply files with the following structure:

- a "vertex" element has the properties "x", "y", and "z" specifying its coordinates
- a "face" element has a property list "index_vertices" specifying the
 indices of the face

The program itself reads from a ply file and writes to an off file.

It hasn't been extensively tested and I'm not much of a C programmer. If
it breaks you get to keep both pieces ;)
