Well thanks for the answer, but I'm not sure what to make of this. Does it mean
that I scan the entire list of normal_indices, and when a particular index of a
vertex_vector never appears in it, it means that this particular vertex_vector
has no normal_vector?

Well currently my program is using .3ds files for the preview and POV mesh2
files for the final raytracing in POV. Works, sure thing. It would just be more
elegant if the preview renderer could read the pov files as well, then I
wouldn't have to deliver the geometry files twice in two different formats. :)
Clearer now? :)

Btw, thanks for your replies so far. :)
