I agree. For development, UNIX based systems are just superb (imho). I also
learnt quite a bit about the system from actually setting it up. It's kinda
satisfying once it's up and running and you've overcome the challenges!

I'm doing exactly the same thing, except under X-Windows. The main reason
being that I can run my program in one X-Window, debug from another
(Using Xddd) then just change the start-up code for DOS once it's
finished, slap it through djgpp and the thing works fine. I love it :)

I *strongly* recommend developing under X-Windows. The viewport is handled
just like DOS's mode13h (using MIT-SHM or just straight XImages) and is
*very* fast. The conversion rate is approx 200fps on my P5-100 running a
Mach64 X-server. This time includes rotating 24 points and clearing the
screen buffer (coded in 100% C).

Sorry, I don't use them. Also, most of the existing ones require X (I think),
and you're (most likely) using svgalib. You need something like Mesa or
OpenGL. These are well supported and OpenGL is pratically standard. There's
also a guy here on r.g.p that has knocked up a library called Free3D.

Hope this helps,
Jon.
