Individual process table slots are cheap.  It's only when you start
talking about dozens and grosses of them that they become expensive.

Rtnetd is turned on for multiprocessors because it significantly speeds
up TCP/IP when you're using FDDI or (I presume) several ethernets at
once.

You could certain turn rtnetd off.  I wouldn't, to avoid having the
configuration of the machine be any more distintive than absolutely
necessary, should reloading the disk or just installing a new release
be desirable.

Using sysinfo to get the ethernet address is a Bad Idea, at least with current
versions of IRIX.

If SGI ever gets its act together for system ID's after these last 6+
years of trying, the already very tenuous connection between the sysid
and the ethernet address will fade entirely.

As I recall, the main thing that kept ASD platforms relating the
system ID with the ethernet ID was downward compatibility.  Future
systems do not have that constraint.


Instead, use `netstat -ina`.  It is supposed to return the MAC address
and does.  With netsetat, you don't have to make fiddles about the
relation, if any, between the system ID and any of the network MAC
addresses.

Subject: Re: Matrix multiplication in GL
Organization: IGOAL
Date: Thu, 5 Nov 1992 18:39:47 GMT

There is a way to use the GL to multiply points. 
  1. Load the transformation matrix using loadmatrix()
  2. Create another matrix where the point is a vector in the 4x4 with [x,y,z,1]
  3. use multmatrix() to multiply the vector matrix by the loaded matrix
  4. use getmatrix() to retrieve the resultant matrix and look in the appropriate collumn or row
     for the result of the transformation.

Might I make a suggestion though, from my extensive use of the matrix multiplication and doing
point and normal transformations, NOT using the GL is much faster.  If you create routines to
multiply a point by a 4x4 matrix or 4x4 times 4x4 matrix, or normal by 4x4, and set the values for
the result by longhand.  The answer is returned DRAMATICALLY quicker.  By "longhand," I mean...

xprime = x * mat[0][0] + y * mat[1][0] + z * mat[2][0] + mat[3][0]
yprime ...
newmat[0][0] = ...

Hopefully you get the picture.  If you do timing test on GL versus non GL, I think that you will
find the NON GL version to work much quicker.  Try a simple test program for a 1000 point transforms
That should show a major difference between the two methods.

The reason you save so much time is the load and get take lots of time and your transformation
ignores the 4th collumn of the matrix on point and normal transforms, thus saving operations.

Try it and see what happens.

goza@cheers.jsc.nasa.gov


PS.  Another speed up for your code is the abs() function that most people use.  _ABS() is much
     faster than abs() or fabs() and it works for integers or floating points.  It is in math.h and
     is nothing more than a conditional if...

     #define _ABS(x) ((x) < 0 ? -(x) : (x))

     Try that as well, I think you will find it faster.

Greetings,

I've been using rectzoom and lrectwrite to display
images in mixed-mode Motif/GLX programs.

I have restricted the zoom parameters to integer values
for better support among different models.  (the manual
explicitly states that non-integer values don't work
on many models)

However, even with integer zoom values, it only works on our VGX.
It doesn't work in our Indigo-Elan, Indigo-XS24 or 30TG.

A breakdown of where it works and doesn't:

Model		OS	does it work?

4DVGX		4.0.4	yes
4DVGXT		4.0.5	yes
30TG		4.0.1	no
Indigo-Elan	4.0.5F	no
Indigo-XS24	4.0.5F	no

Please send e-mail to me, since I can't keep up with the

Thanks, for your help.

Some of our users cannot start workspace. It simply hangs as a process

The users have home directories that are accessed via NFS. We don't run
Yellow Pages (and we don't want to!).

However, for some users it IS possible to start workspace, even though
their home directory is accessed via NFS.

We run 4.0.1 on the machine to start workspace, and 4.0.5 on the machine
that exports the home directory of the users in question.

Does anyone know anything about this???

The description of complex shapes (triangle meshes and face sets) in a  
scene graph would normally consists of separate nodes describing info
like coordinates, normals, transformations and the shape node itself
right?

And during rendering traversal, different sets of elements in the
rendering traversal state can be altered by the given class of nodes. 

My question is how can I gain access to information such as current
coordinates after a transformation for example without computing it
myself?  since the traversal would already have done these calculations.


Or do i have to access the coordinates directly from the coordinate node
itself, determine the transformation from the SoTransform nodes and then
perform the calculations.

Please advice. Thanks

Problem: Logging out from a session under 4.0.5

We have succesfully installed 4.0.5 on our Indigo's.

However, some users have a problem logging out. It is those
users who have a line in their .cshrc file like:

setenv DISPLAY `hostname`:0.0

- I know that there are better ways of doing this, but this is
not the question here. (Using REMOTEHOST etc.)

When they select the Log Out menu item from the 4Dwm, and
answer Yes to the question, nothing happens!

If you look at the /usr/adm/SYSLOG file on a machine called
iris6, it will tell you something like:

/usr/bin/X11/xprop:  unable to open display 'iri'
usage:  /usr/bin/X11/xprop [-options ...] [[format [dformat]] atom]
etc.etc.

It seems like something was changed in the endsession script file - why?

If I change it back to what it was under 4.0.1, there are no problems.

4.0.5:

PROP_DISPLAY=`expr $DISPLAY : '\(.*\).[1-9]' \| $DISPLAY`
/usr/bin/X11/xprop -display $PROP_DISPLAY -root -remove _SGI_SESSION_PROPERTY

4.0.1:

/usr/bin/X11/xprop -display $DISPLAY -root -remove _SGI_SESSION_PROPERTY

It seems like this expr expression doesn't work, if there are digits in
the machine name...

What is the purpose of this change? What will go wrong if I change endsession
back to what it was under 4.0.1?

 You will need a PostScript 'Interpreter' to do this. Ghostscript is a
PostScript interpreter and can convert PostScript file to GIF format
image or X bitmap image. If you install ghostscript, you can convert
PostScript image to some bitmap image, and convert it to IRIS image.

How does one make a suggestion regarding the TAC?

The problem is that the TAC personnel don't consider that there are
four time zones in the U.S., and that SGI is located in the westernmost
one.  My calls are CONSISTENTLY returned after working hours in
the Midwest (usually I get a message time-stamped around 6:30 pm or so).  
This requires at least one more round of phone tag before getting in
touch with the engineer.

I called the TAC and asked how to register a suggestion/complaint, but
the person on the other end didn't know how to go about it.  I'd like
to target my suggestion a little more closely than just sending a letter
to the CEO of the company.  Any suggestions from you SGI folk out there?

My intent is constructive.  In the end this ought to be good for SGI too,

Nope.  As mentioned here before several times (and also as our support people

Hi folks, sorry if this is an old question, I'm new to the sgi and

When an unformatted file is created with FORTRAN on the SGI, is it
unstructured (like a plain old binary file, no record markers), or
does it have some goofy record structure?

Essentially, I'm hoping to read a binary data file with Dscribe from
Explorer, and the file was created with SGI fortran. Having trouble,
and it said something funny about markers, or structure, I can't quite
