This in regard to the comanche-like engine hgtf_1-0.zip, found at
ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2/
I don't understand your point. If memory serves, the guy who wrote
jlib isn't selling it, and provides all source (also available at the
above site). He only uses jlib for the port, not the original demo
author's lib.
Fact is, the jlib author (Jonathan Griffiths, I think) doesn't
actually rely on jlib all that much in his djgpp port; mostly for
convienience things like dealing with reading the bitmaps and the
like. The real machinery of the engine is pretty much straight C-code.
Anyway, I'm still hoping to understand how this program works better;I
can follow it's details, but I'm not sure why it does what it does,
the overall picture. I think at this point the problem is that I don't
understand the principles behind this sort of high-speed heightfield
rendering, and I don't know where to look it up. Most texts I've seen
are concerned with high-res/ultra-slow graphics rendering for "art"
sorts of pursuits, not lo-res/lo-precision speed rendering. Any ideas
where to look, or clues as to the overall picture of how this little
engine works?
