I take it  you guys are talking about this comanche-like engine:

>ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2/hgtf_1-0.zip

I thank the guy who wrote Jlib for porting this. It is a very
interesting engine. Nevertheless, I am having a hard time
understanding it- I don't understand the basics of this sort of
rendering, "heightfield rendering." For example, what does the
sine/cosine table do, and how is it implemented in the drawing? I have
a hard time even figuring out how he is doing the actual line drawing.
I mean, I have the code, but I just can't seem to follow it out to the
big picture of what makes this engine tick. But it is a remarkable
engine, for something so small. Any clues, anyone?

Please post in this thread.
