- resolution of the ouput device (ie, the printer), unless I misunderstand.
- 
This ain't necessarily so.

Many 3D primitives could be implemented in PostScript or as an extension 
to it, for example:

Raster concepts:
   Z-buffering - just add memory and use it well
   Depth cueing - Some algorithms would be needed, but the main problem 
        is how to map to the lower resolution of the printer (a 72 DPI 
        screen 24 bit deep) has about as much or more information per 
        area element than a 300 DPI 3col/dot CMY printer)
   Goraud, Phong shading - dito
   Alpha blending - a doddle, just needs a bit discipline and that Z buffer
   Texture history - not required

Vector concepts:
   Back face removal - a doddle in postscript
   Depth sorting (i.e. plot from back to front) already used in 2D

Many of the operations are not so time critical, because you need one (2400
x3500) frame in 30 seconds, as opposed to 30*72 1024x1280 frames. Thus the 
screen displays about 3000 times as many bits in that half minute.

The main problem is again between vector and raster displays. If you send
raster graphics across any communication link, you want a very high speed 
link. Using then a vector mechanism to encode raster information (as in
a sending a (x y z moveto a b c rgbvalue x y z lineto) for each point makes
it rather worse.

use a block device to mount a filesystem, not a character device.  you need
to create a block device in /dev/dsk in order to mount a floppy as a efs
filesystem.  see mknod(1m).

note: use the same major/minor numbers as the character device when using mknod.

I think this is a "well known" xterm bug.

The easiest thing to do is switch from xterm to xwsh.  I used 
to be a die hard xterm user, and converted to xwsh just because 
of the xterm cut-n-paste bug.  Since then I've found xwsh is really 
much better (unless you really need that xterm tek mode).  

xwsh uses less memory, the fonts menu blows away xterm's, and it 
generally tends to be more robust.  

Before anyone cries foul over GL depenancies:  xwsh is a pure X protocol 
program (yay kipp!) so it'll talk to you X terminal or other X servers.

The old cdplayer app saved the title and track info in

I'm not quite sure about what a bullet is :-), but I assume You talk
about a dot that is a little thicker, right? (Wes said something about a
bullet looking like, but not being a filled circle). I just tried
Showcase 2.0 on IRIX 4.0.1 and succeeded in getting the bullet character
(as I hope it is) by typing <Ctrl>-<Alt>-8. By additionally pressing the
<Shift> key You get a smaller bullet. (I just had a look into my
dictionary and it says that we seem to talk about the same thing :-)

Hi,

Is there  a shell, script, application ... that allows me to share one account?
The idea is to share an account into several users (like doctorants from a
department), requesting from them:

1. the userID and password of the Department, and then
2. their own userID and password

At this time, each student should be located at their own directory (actually,
a subdirectory of the department's one) and allowed to work normally.

Thanks in advance,

With OpenGL as an X extension, non-direct OpenGL rendering  will go
through the X server to do graphics. On SGI platforms, that rendering
will be as efficient as the current DGL path. (The token stream will go
to the X server but it will not be rendered through the standard DDX
layer within the X server.)

Direct renderers will continue to address the graphics pipeline without
going through the X server.

It would be very surprising if an X terminal manufacturer would bother
to license and implement the DGL protocol; DGL is being supplanted by
the GLX protocol (which is how OpenGL rendering works in the X
environment).

[XGL is the name of Sun's proprietary rendering interface. It is neither
X nor GL.]

Sounds like a memory corruption problem.  Different malloc libraries
will behave differently when the heap is corrupted.

You might want to try using WorkShop's HeapView and debugging malloc
library, or try Conor P. Cahill's malloc library which is available as:

'edge' is GL based program, not an X program. (It does all of its

Yesterday I upgraded a 210 GTX from 4.0.1 to 4.0.5A. I did this mainly
because we had problems with using dials and buttons in Polygen's 
Quanta(3.2.3), a molecular modeling software system. We were told by
SGI that this upgrade would fix the problem. Unfortunately, the upgrade
gave rise to some additonal problems. Now Quanta wouldn't even start.
I suppose the problem is due to some font settings. I noticed the following.

1. When started, Quanta's main  window remains blank for sometime and then
   exits with a coredump.

2. Another GL program for which we have the source code also dumped core.
   It gave the following  information in dbx.

However when I checked up /usr/lib/fmfonts I found all the necessary fonts.
I compared the contents of this directory with that of an Elan we have here
and it looks fine.

4. Not one of the menuitems in showcase 2.0.3 is selectable. The menu items
   are not desensitized but they are also not highlighted when I move the
   cursor over them. 


I am not aware of the known problems with 4.0.5A. I hope the above problems

Hello everyone!

   I recently finished doing a program which, I'm sure, one or two
college sys ads would like to have.  It is called the Terminal
Allocation Program - or TAP for short.  All it does is allow people
to sign up for usage of whatever computers are on your network.
   The program is nothing fancy, but looks rather nice.  It works
well, and is modifiable.  So why am I posting?  Mainly because I'm
looking for to some site which would be willing to take a tar'ed and
compressed file so whoever wants to use the program can have a copy
of it.
   The file does NOT contain a compiled program - only source.  This
is so you can compile it on your system.  It is written in C using
the X Windows environment and X Motif on SGIs using v4.0.1 of the
SGI OS.  I also have an older version which runs under SGI GL, but it
is no where near as far along as the X version.  (This is because
it was decided that writing it using X and Motif would give me lots
of experience in it - which it did.)
   Anyway, if there is a site which would like to hold the source
code (with the Makefile included) - let me know.  Thanks! :)
