Dear Mr. Kennedy,

        Could you please verify my subscription of the
info-iris list - I belive that I subscribe it, but I'm not sure,
since I did not receive any message form info-iris.
        If I'm not on the list, could you please add me? I would
like to know if the list is active or not - I know that the sgi
newsgroup is active but I don't have access to net news...

        Thanks in advance,

        forgive my bad english,

I've put the following in my .cshrc (or .alias) file:

	alias pwd 'echo $PWD'

It's generally not a  good idea to refer to  files/directories through
the automount mount point  since those mount points don't always exist
and they can change depending on how the automounter is started.

Is there any way to use the audio port as a raw output port ?
	i.e.  --> if I want a '01000001' bit sequence to come
out then I could just echo "A" (41hex) > /dev/audio ??????
	Is there anything I'd need to set up first ?
	Can this be done with a serial port and somehow getting rid of
all the start/stop/parity bits ?

Thanks in advance

Yes there is.  ki Research sells a product called openDNA which includes
DECnet, MOP and LAT protocols.  It also contains a software network
analyzer.  The LAT protocol can be purchased seperately from the entire
product set.  Also available is a VT340 emulator.

openDNA is available on many platforms such as IBM RS/6000, Sun4, Sun3,
HP 9000/{300,400,700,800}, Sequent, Encore, Mips, Ultrix, Modcomp, Harris,
and many others.  The interface is identical on all systems.  Included
with the product are Application Program Interfaces to all the protocol
stacks.

Our LAT software supports incoming, outgoing, HIC printing outgoing, 
HIC printing incoming, password support on outgoing connections.  The
install process is automatic and requires limitted user input.  Users
may even create their own services and are not limitted to only /bin/login
as a service.  We distribute a lat to telnet gateway as an example of
an alternate service.

Give us a call for a free trial copy.  1-800-945-4454 or send email
to support@ki.com.

Several people were kind enough to point out to me that Posix and/or BSD
signal functions are only prototyped if __EXTENSIONS__ or __POSIX_SOURCE are
defined (and they are in "-xansi", or default, mode).

I can no longer reproduce the complaints about void pointers, so I am
asuming that I was doing something something strange (and/or wrong).

Thanks to the people who responded.

As far as I know (and I'm not in support, or in upper management ;)),
the next general release automatically shipped to everybody on
maintenance will be the one that has SVR4 etc.  support in it.  I don't
think a date has been announced for that one yet, other than "not for a

Don't wait.  At worst, asking for something you are going to get anyway

The SCSI drives shipped by SGI now are far more reliable than the old SMD drives
and in fact offer much BETTER performance than was possible with SMD.  The SCSI
spec has advanced rapidly while SMD stood still. Go for the SCSIs.

I posted about this a week ago, but I don't think it got onto the net!

We are running accounting on our 6 machines.  4 are diskless, and the
accounting does NOT work properly on them.  2 have disks, and the
accounting works fine.  Does anyone know about this?  Is it a known
problem?  Does it have something to do with the "w" command giving
incorrect idle times on the diskless machines (which I was told is a
known problem).  Any help appreciated!!

Date: Thu, 13 Aug 1992 12:03:18 GMT

Because the make-behavior described here might trip up another, I note
that whitespace at the end of a "SHELL=" line in a makefile is
significant.  (I use 4.0.2 IRIX.)

For example,

# A makefile
SHELL=/bin/sh 
#            ^ = a space.  It could be a tab.
target:
	ls
# end of makefile

% make
	ls
Couldn't load Shell: No such file or directory

Stop.
*** Error code 1

Stop.

If I remove the space (or tab), all is well.  It doesn't help to end
that line with a #.

With SGI the last program is not the windowmanager but special windowless
program called "reaper". It terminates when you answer "Yes" to the 
prompting program "endsession".

This is very nice since you may now change the windowmanager on the fly
without getting nuked. It's even an option in Toolchest.

In addition to supporting multisample antialiasing, RealityEngine also
supports pointsmooth, linesmooth, and polysmooth algorithms as used on
the VGX.  RealityEngine polysmooth is also MUCH faster than VGX
polysmooth, and gives higher quality results.  A 2D scene, such as a
clock face, is probably better rendered on RealityEngine using polysmooth
than using multisample, because it will work on any RE, regardless of
how many raster boards are installed.

Hi!  After working with GL for some time now, I have a burning question about
lighting.  I have thought this problem through, and I just cannot think of
a good way around the problem, while at the same time I cannot believe there
is not a solution!

There seems to be a mismatch between our lighting model and GL's.  Ours uses
coefficients for all lighting properties (diffuse, ambient, specular, etc.)
plus object and light colors.  When the lighting is done, the object's and/or
light's color are combined with the appropriate coefficients to light the
object.  Often we have vertex-colored triangle strips (each vertex is colored,
and the colors are interpolated across the triangles), and we want to be
able to adjust the diffuse, ambient, and specular coefficients separately.

GL, however, has the notion of diffuse COLOR, ambient COLOR, etc.  This
really throws me, since it seems to me that the COLOR and the COEFFICIENT
should be separate.  That is, you should be able to set the diffuse &
ambient coefficients and then go about coloring your triangles.

When I want to draw a bunch of shaded, colored triangles (with a color per
vertex), I do a c3f(), an n3f(), and a v3f() to pass the color, normal, and
vertex.  What I want to adjust the ambient coefficient of the model I am
rendering?  I don't see a way to do this unless I actually multiply each
color component by my ambient coefficient FOR EVERY VERTEX (pretty time
consuming!).

What I do as a compromise to all of this is set lmcolor to LMC_AD.  Then
I set the ambient light intensity to 0.3 times the intensity the user
wants.  This has the effect of giving me ambient and diffuse lighting that
matches the object's color.  Unfortunately, the user cannot adjust the
ambient coefficient on a per-object basis.  In the vertex-colored case,
the user cannot adjust the diffuse coefficient either!

Has anyone else run into this problem?  If your application's lighting model
follows the GL model (i.e. lets the user set the diffuse and ambient COLOR
for an object), there would be no problem.  But hoe does one deal the the
vertex-colored case?

Am I missing something obvious?  Please respond via email...  I may miss it
in this newsgroup!
