Oh, I can contribute here?  I am just starting to learn
C++, don't know much ;)  I've read what a raytracer is,
and could probly explain it to you, but it would be
better for you to read what I've read, so go to
povray.org.  While you're there, you may want to
download it, as povray is a free one.  I think the
difference between raycasters and raytracers may be the
difference between starting at the light source, and
starting at the camera, not sure.  I believe povray
uses both techniques, to get mirrors to reflect
properly, or something.  Somewhere on their site, they
say that raytracers are not very good for games yet, as
the raytracing process is horendously slow, and game
graphics are generally rendered in real-time.  So I
suggest you temporarily forget the idea of raytracing
for games, until computers do an even better job of
blowing our minds away.  So, you want to make a 3d game
from the bottom... meaning you don't want to use OpenGL
or DirectX or suchlike?
