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/
"
