Main structure is builded similiar to all raytracers.

1. Take the point on screen.
2. Calculate ray for this point
3. Test all objects this ray can intersect.
4. Get nearest interesected object from all hits.
5. Calculate color this intersection
6. Put color on the screen

But I suppose you already know this :-)

There is dedicated chapter for POV-Ray internals in MegaPOV manual. It will be
extended in future versions probably. You can find it at
http://megapov.inetart.net/manual/internals.html
