Not to burst anyone's bubble here, but...
Any SOB can pick up a book for $30 or so that has a working ray
*casting* (not tracing) engine, implemented in C and psudeocode.
It's not 'highly secretive'. See above, or go to any major source code
archive, and you can pick up the source code to Wolfenstine 3D itself
(legally), ACK3D, and many other engines, usually with source.
Anyway, the above post was a fairly good introduction to raycasting, even
though it had it's faults and a little sense of bloated ego.
