I would guess it is much simpler to have a look at the formulas
in the source, than try to explain it by abstract mathematical
formula, because -- as a consequence of the way raytracing works
-- the cameras are defined "backwards", i.e. you enter pixel
coordinates and the camera constructs a ray.

The Function is called "create_ray()" and is located in RENDER.c
It is really pretty much self explaining... :-)
