RayCasting <> RayTracing.
You are referring to "raytracing" programs. I'm talking about raycasting.
The difference: As explained by somebody after I did a quick google
search to save time:
"
wolfenstein3d used raycasting. Raycasting is based on sending out a
"ray" along each line of sight from the viewer, and incrementally moving
along that line of sight until the ray hits an object.
Ray Tracing involves letting rays reflect off of objects to
produce a realistic-looking scene with reflections and shadows. Ray
tracing is hard to do fast enough to include in a game. if you want to
see some examples visit http://www.povray.org/
