My advice would be, start simple!  Your first program would preferably not
even display the image, just calculate it and save it as a PCX or something.
(But if you're using Allegro, I guess it's not much work to display it just
before you save it...)

The simplest shape is probably a sphere.  So when you shoot your ray out of
every pixel, you only need to do a sphere intersection.  The colour of the
pixel depends on what part of the sphere you hit.

Anyway, I'm probably not being much help, am I?
