Does anyone know of a good reference for C or ASM SOURCE code or
general algorithms for primitive graphic elements (i.e. lines,
ellipses, arcs, polygons, regions, etc.)

Specifically, I'm writing a graphical library for a windowing system
similar to Quickdraw or MS-Windows GDI. It will be run on 80x86 machines
with at least VGA graphics. The biggest problem I'm having is implementing
regions, especially clipping regions.  Each of the primitive routines are
clipped to a region. A region is a combination of shapes which can take on
any form. What is the best (i.e. fastest) way to implement a system like
this? Any help at all is appreciated.  Thanks,   Doug

Subject: SOMEBODY PLEASE HELP ME!

   I am a freshman at Carnegie Mellon University and I need some help. 
At CMU, students don't declare their major until after their sophomore
year.  Right now, I've kind of decided on majoring in Creative Writing. 
However, what I think would be way cool to do is develop my own major
called, "Computer-based Multimedia Development."
    The major part of developing my own major is formulating a proposal
to be submitted to the Academic Head-Cheeses so they can decide to give
me the go-ahead.  But as a part of this proposal, I have to pick several
existing classes that would be useful in pursuing my desired major.  In
my idea for Computer-based Multimedia Development, I'd think it would be
necessary to include classes that teach understanding of sound
recording, music, graphics, animation, and even use of multimedia
programs.  Of the classes I have put in my plan, some are in the Design
Dept., some are in the Art Dept., some are in the Music Dept., and some
are even in the English Dept.  Still, all of them teach some integral
theme to understanding and developing multimedia.
    The classes I have included are listed below, with a short reason
why I chose them:

Physics of Musical Sound                       These are all classes that
Keyboard Studies I/II, III/IV, and V/VI       are concerned with developing
Sound Recording I/II                           sound and musical skills.
Electronic and Computer Music I/II

Electronic Media Studio I/II                   These classes deal with using
Computer Drawing & Painting I/II               computers for animation and
2-D Computer Animation                         multimedia production.
3-D Computer Animation
Interactive Multimedia
Electronic Print and New Media Production

Documenting the Visual                         These classes teach fundamental
Integrating Visual and Verbal Text             uses of color, graphic
represent-
Color                                          ation, and typography. 
They also
Typography 1, 2, and 3                         deal with how people perceive
Non-Verbal Communication                       and communicate with images.
Information Design
Visual Language
Kinetic Typography
Visual Interface Design


    But I need more.  If anyone out there can help me, this is what I ask:
What are some things that somebody majoring in Computer-based Multimedia
Development should be learning how to do?  What benefits could I get
with a degree in this?  I am aware of the uses of multimedia for
animation, presentations, information kiosks, demonstrations, etc.  But
what reasons can I give the faculty at CMU to persuade them to let me
pursue this?  Any comments and feedback is much appreciated, and I will
try to get back to anybody who responds to this.  Thanks.

I don't know if this is appropriate for this group, but I am pretty
desperate, so here goes:

I am in the process of porting a piece of code from VGA Mode 13h (320 X
200, 256 colors) to VGA Mode 12h (640 X 480, 16 colors).  I have art
that has been algorithmically converted to 320 X 200, 16 colors then
touched up by hand.  I am expanding this art by doubling all of the
pixels on the fly when I load the images into memory from disk, and
leaving 40-pixel-tall blank strips at the top and bottom of the screen.
Hence my final image size is 640 X 400.

My problem is that my blit routine is slow.  I am presently using write
mode 0 (byte-at-a-time) and addressing each of the 4 bit planes
separately.  Since I am inexperienced with Mode 12h and EGA-format
graphics in general, I am wondering if I am missing something.  My
understanding is that in mode 12h I do not have access to page flipping.
Is this correct?  If so, does anyone out there have any suggestions for
fast algorithms for moving rectangular regions from main memory to the
screen in this mode?  BTW, as far as the registers go mode 12h behaves
the same as the old EGA mode 10h (640 X 350, 16 colors) for anyone who
has worked with 10h.

I am under rather severe deadline pressure, so prompt advice of any kind
would be greatly appreciated.  However I don't have any choice about
this -- as kludgy as it sounds (is) I *have* to do it, so please spare
the flames.

Please e-mail me as I do not regularly read this group.

Thanks!

I am looking for a general purpose scaling algorithm.  We have one to do major

picture compression or expansion, the ticks are on top of each other or miles
apart.  I know that lots of graphics programs use such algorithms, but is there

Maybe its stand-alone, or maybe part of another program?

Get the pbmplus package from Jef Poskanzer (from wuarchive.wustl.edu, 
directory graphics/graphics/packages/pbmplus for example).

There are filters for converting m a n y picture formats including GIF
using a general pixmap format. (It's a source only distribution, precompiled
binaries for various boxes are available, too.)

Hope this helps.

I have done some programing in BorlandC for the AT&T TARGA24 board (now theres
a board for rendering) If you call a TRUEVISION distributer, they can sell

Check out "Iff2Ps" on Fish Disk 94.  It works quite admirably.  Takes a little
while (i.e. a few minutes) on a 7.14 MHz 68000, but has some nice options for
grey scale, etc.

Does anybody know of anything that will give you color postscript output from

Green and Paddon, from the University of Bristol, did similar work to
Priol/Badouel in 1989. See there paper in IEEE CG&A Volume 9, Number 6,
November 1989. Its title is ``Exploting Coherence for Multiprocessor Ray
Tracing''. They also have a Tech Report out: ``A Highly Flexible

  The other big question is how do YOU write apps as spiffy as SGI's demos?

It's getting to the point where the app (i.e. C code) isn't
necessarily the biggest part of a really spiffy demo, the
database modeling is.  Two reasons:

	1) High level toolkits like IRIS Performer and 	IRIS
	Inventor are making the application code shorter and
	easier to write.

	2) The realism that Reality Engine provides comes from a
	lot of very fast, very high quality texturing.  To use
	this effectively you need to assemble texture images with
	3D geometry.  Most apps won't do this entirely in C code.

As an example, the town drive through demo that was shown at
IMAGE and SIGGRAPH is only a few lines of code on top of the
sample application code that comes with IRIS Performer.  But the
database required going out and taking pictures, scanning them,
processing them for edge matching, blanking out transparent
backgrounds, modeling the geometry of the terrain, the streets,
the curbs, the buildings, placing all the trees, streetlights,
signs and parking meters, applying the textures to the
geometry... No need to touch C code, but even with an expert
using good tools, it takes a while to do.
