The next meeting of the South Texas SGI User Group will
be held at The University of Texas at San Antonio
on Friday, February 12th starting at 5pm.

Free food and drink again will be provided by UTSA's
Center for Information Visualization :-P

Come and test drive a REALITY ENGINE!

And if you promise not to tell, SGI tekkies will
be on hand to describe new *secret* SGI products! 
(If I say anything more here on the net, SGI has
threatened to have me transferred to Texas A&M :(

A more complete announcent will be posted in a few days.

Hope to see ya'll on February 12th.

I am not sure that this is the right place to ask, but
does anyone know if it is possible to get GL to display
in an X-window on a remote non-SGI machine?  It doesn't
have to be fast.

I assume that compiler you are using is based on AT&T 3.0 or 3.0.1. In both
of these versions the compiler only looks in libraries which are linked on
the command line using an explicit pathname. ie. .../libfoo.a. The compiler
does not resolve a library link directive of the form -lfoo into an
absolute pathname before passing it onto the link simulator. So if you are
using -lfoo then you might want to try giving the pathname to the library
instead. This is a real pain if you wanted to use a shared library. :-(

From what I have heard this problem will be fixed in the AT&T version 3.0.2
compiler.

BTW, we have hacked our CC script to fix this. If your compiler still uses
a shell script for CC and your interested in the fix then mail me.

I'm trying to record some images to tape, by setting my Indigo XS-24Z
to PAL mode and running the output through a PAL encoder. I'm having
trouble getting decent colour onto the tape, so I am interested in the
experiences of people on the net. So far, I've been fiddling with the
Indigo gamma value and the R, G and B levels on the encoder, but
without decent results. Any tips would be welcome.

Keywords: mkfs root user prototype
Date: 29 Jan 93 04:23:23 GMT
Organization: Duke University Computer Science Dept.; Durham, N.C.

I am creating a new filesystem on an optical disk, and I would like to make 
the root directory of that filesystem owned be someone other than root.  I can
do this with a prototype file that looks something like this:

/stand/diskboot
4872 110
d--755 <uid> <gid>

However, without any options, mkfs creates a lost+found directory and fills 10
disk blocks with zeros so fsck can reconnect disconnected files.  When I use
the prototype file, I don't get the lost+found directory anymore.  I can add a
line that will create the lost+found directory, but I don't know how to fill
10 disk blocks with zeros.  Does anyone know how to do this?

Basically, I want users to be able to format their own disks for this system,
and to do that, the filesystem created by mkfs can't be owned by root.  The
prototype file seemed to be the only way around this, but if anyone knows of a
better solution, please let me know.  Thanks in advance.

We have run the "PostScript Processing speed test" P2ST on an
R3000 Indigo and found it to be about 20 times faster than an
Apple LaserWriter II NTX.  On an R4000 Crimson, its about 40 times
faster.

What kind of 2D graphs, specifically?

I have found that gnuplot generates PostScript output code that is
very easy to customize.   One window with an editor session on the gnuplot
postscript output and one window of ghostview (I suppose xpsview would 
work as well) makes a pretty reasonable environment for fixing up
PostScript plots for publication quality.

I am still not happy with the gnuplot contouring code, but I have
not spent much time trying to hack it into reasonableness....

If you switch to GNU make, you won't have to worry about version differences

build our software (~ 1000 source files in ~ 30 subdirectories). Like
murdoch@acc.Virginia.EDU, we keep our object files in subdirectories of the

on IBM RS6000, Convex, and Stardent GS2000. Porting GNU make to a new
machine has been pretty painless in all cases.

This is not to say GNU make is without problems. It is the kitchen sink of
makes, much like GNU emacs is the kitchen sink of editors. (Most of the
people in our development group love GNU emacs as well, but that's another

Under IRIX 5.0, you should be able to use shared libraries, since

I have a program which defines a couple different cursors and switches

reports seeing:

ERROR #57  curorigin: ERR_CURSORNOTFOUND

My program does not call curorigin(), it merely uses the default when
defcursor() gets called.

I'd appreciate any information the net might have about this.
(all I have is 4.0.1, without 4.0.5 I'm having a tough time determining what's
 going on)

PS: also under 4.0.1, is it expected for sscanf() to break the context of

I think it would be better if SGi moved the dps_dev (Display PostScript
Development System) from the IRIS Development Option (IDO) package onto
the Laser Printer Support (LPS) package and in stead of the dps_dev, SGi
could supply the Documenter's Workbench (DWB) with the rest of the IDO
package (developers do make man-pages, don't they?). I think these would
make a MUCH BETTER combination!

What is the opinion of all you SGi-machine users out there ?!?!

You must be in mult-matrix mode, that is mmode(MVIEWING). When in this
mode, the
perspective matrix is separated from the modeling-viewing matrix stack.

Try this:
getmatrix(modelViewMat);
mmode(MPROJECTION);
getmatrix(projMat);
mmode(MVIEWING);

Then use your favorite matrix mult routine to get M = Mmv * Mp.

Here's a more detailed explanation that Kurt Akeley posted a while ago:

    1.	Transform your point by the current matrix (if in single matrix mode)
	or by the ModelView matrix followed by the Projection matrix (if in
	multiple matrix mode).  Matrix mode is controlled by the mmode()
	command, which also controls which matrix is returned by getmatrix().
	Set the W component of your point to 1.0 prior to transformation.

    2.	Clip the resulting transformed point against all 6 clipping planes:

		if (x > w OR x < -w OR y > w OR ...)
		then the point does not have a screen coordinate

    3.	Project the transformed point by dividing each of x, y, and z by w.

    4.	Map the point to window coordinates using the equations:

		Xwin = Vsx * X + Vcx
		Ywin = Vsy * Y + Vcy
		Zwin = Vsz * Z + Vcz

		Vsx = (right-left+1)/2
		Vsy = (top-bottom+1)/2
		Vsz = (far-near+1)/2
		Vcx = (right+left)/2
		Vcy = (top+bottom)/2
		Vcz = (far+near)/2

    5.	Add the window offset to Xwin and Ywin to get screen coordinates.
	Z values are not affected by window position.

I've written the Z viewport to be identical to the X and Y viewport operations,
but some SGI machines are off by one on this mapping (no big deal usually).
All computations should be done in floating point.  If screen coordinates are
to be coerced to integers (generally not a good idea) be sure to round toward
nearest.  If truncation is easier, add 0.5 to Vcx, Vcy, and Vcz.

Is your tape drive connected to a Mac or to an SGI?  In a mixed
MAC/SGI setting, one way to do it is to put the tape drive on
a MAC and use Retrospect/Retrospect Remote backup software, an
*excellent* product.  Then use NFS/Share on the MAC that has the
tape drive to mount the SGI's hard drive on the MAC's desktop.
Retrospect can back up from anything mounted on a MAC desktop.

If the tape is on the SGI then you'll have to use UNIX backup
software of some kind, and use CAP (Columbia Appletalk Package)
to let the SGI speak AppleTalk.  I prefer having the tape drive
on a MAC because Retrospect beats any UNIX program I've seen
for user interface and flexibility.

Of course, in case of a real major crash, you should have a
backup of the root partition from your SGI that can be restored
locally--you cannot talk to the MACs until you get the system
and the network software running.
