[comp.unix.microport] --- Graphics applications/demo for SysV/AT

fortin@zap.UUCP (Denis Fortin) (03/10/88)

Greetings...

	I was wondering whether anybody out there had any kind of graphics
demo program that would run under Microport's System V/AT.

	Someone mention a few weeks back that he had some basic plotting
routines for the EGA card working (draw line, etc).  That sounds like a
good starting point towards developing a plot(1) program for SV/AT, along
with a matching plot(3) library...  (Maybe he could post his package,
or E-Mail it to me?!?)

	Anyway, if absolutely no PD stuff exists, I'll probably try to
get something to work in the next few months...

I'd like to know if anyone has something similar for Hercules clones?

I like monocrome displays for programming, which is what I do, and
besides the price is right.  But being able to bitmap the thing
is occasionally handy, for instance for previewing TeX output...

Of course trying to get TeX to run on a 286 isn't going to be
fun, but that's another story...  (anyone got info on pascal compilers?)

I have a friend here who has some drivers written for HGC cards for MS-DOS,
written in MASM.  You could convert them to use on uPort by calling the
shared memory system to get the segment for the HGC and then saving the
resulting segment in a global the graphics driver would have access to.

If you're REALLY interested, I'll post them, but it's not _all that_ hard to
do.  Just write a dot-plot routine, and base everything else on it, that's
what Rick did anyhow.  His line-draw routines aren't all that fast, he wrote
them in MS-F77, using his dot-plot routine.  His program is much more
computation-intensive than graphics intensive, he didn't really need the
plotting speed.
