Unfortunately I think hidden lines has to be solved by alternate means but I read that Appel guy's paper on hidden lines and increased my knowledge of the subject by about 0.0001%, perhaps less - too complex for me - I need words of one syllable.  |
You're just a tiny bit of structure and a few dot products away from drawing (convex) hidden line objects. Don't think in lines, think in faces. You have all the code and knowledge to make it work, you just need to determine if a face is hidden, and if it is you just don't draw it.
