Re: DOOM style rendering - Need help

["Brad Broerman" <bbroerman@hotmail.com>]

  Well, I have several books, including: Tricks of the Game Programming 
Gurus, Gardens of Imagination, Black Art of 3D Game Programming, and Foley & 
Van Damme. I also have a degree in Computer Engineering, and have definately 
learned the math. I have written several ray casting engines, as well as 3D 
polygon engines.

  This is a question of what tricks did they use with the data to provide 
the necessary information. I do not have a complete edge list to use a 
generic affine texture mapper, and doing a ray casting style engine is a bit 
difficult with the data present. Since they obviously have a way of doing 
it, I am obviously missing something. I am asking those persons who have 
gotten one to work to give me an idea of what I may be missing.
