Re: Finding edges of a given polyhedra in 3D

Thanks Klaus,

Finding the tetrahedrals of the polyhedra seems to be the task of
combination.
But identyfying which edge is inside which tetrahedra seems to be
similar task as finding the diagonals of polyhedra (which are inside of
the polyhedra).

Anyway I will keep it in mind because I am still looking for solution.

I don't know whether this is homework. You should have some basic knowledge of vector geometry. A tetrahedron consists of 4 planes, and the question if a point is inside is answered by testing on which side of these planes it is.
