Subject: QUOTAS .... questions

Is anyone using the "quota" feature in 4.0+ Operating System? If so, could you
explain how to set it up.

Here is our situation.

We have 200+ users (students) with the $HOME machine being a fileserver. We
have a network of 25 machines that they can log onto, and when they do log on,
their files are mounted    for them onto the machine they sit at (not the file-
server). On the fileserver their $HOME directory is either /usr/student/Userid
or else /usr2/student/Userid ... When their files are mounted to the machine
they log into, their $HOME account is alway /usr/student/Userid.

Please note: also on the fileserver is teaching software and this too is
mounted to the local station that the user logs in on. This software resides
in fileserver:/usr/SOFTWARE and on the local machine is it /usr/SOFTWARE.

I am not too sure about the "quotas". Where/what should be running? Should it
be on the fileserver, or on the local machine that has files mounted to it?.


I want to be able to limit the amount of diskspace that the users can have.

None, really.  Many applications that deal with EPS files,
(especially on the Mac, which doesn't have system-level
facilities for processing PostScript) don't try to interpret
the contents of the EPS file.  They have no idea that the
EPS file you produced in Showcase is all or mostly text-
the application just regards it as an EPS file, that it's
not equipped to fully interpret.

The people who designed EPS planned for this possibility,
and provided for a "preview bitmap" to be optionally
included in the EPS file along with the PostScript
description .  Many applications which import EPS (Showcase
included) will display the preview bitmap if it exists.
Otherwise, they will show a blank space or a rectangle.

When you write an EPS file from Showcase, it doesn't
generate a preview bitmap.  So it is not surprising that
MS Word displays nothing when you import the EPS file.
Have you tried printing from inside MS Word after you
import the file?

Organization: Engineering Animation, Inc.
Date: Sat, 19 Dec 1992 02:16:07 GMT

The following are a couple of irritatingly specific GL questions,
primarily directed towards the GL development engineers at SGI:

FIRST QUESTION:

I'm guessing it's not possible right now, but it seems to me that it would
be really nice to somehow automatically generate high-frequency noise.

This would allow you to get close to textures (even low-resolution ones)
without getting the annoying "out-of-focus" viewer phenomenon.

Someone said that there are plans for allowing for combinations of two
textures at the same time.  Is this true?  This would be a nice general
solution for the high-freq noise problem and would also work well for
times when you want to have (for example) a shiny reflection-mapped wooden
sphere.

SECOND QUESTION:

Is there anyway to do TX_POINT texture interpolation on the alpha channel
(I want 0's and 255's, but nothing in-between) and TX_BILINEAR interpolation
for RGB components of a texture map?  I'm generating a field of trees using
tree textures mapped onto polygons.  I'm using afunction() to disable the
drawing of pixels with alpha of zero.  (Please don't tell me to sort the 
forest in back-to-front-order -- that's cheating!)

It would be nice if you could do a afunction(255,AF_EQUAL) or
afunction(0,AF_GREATER), but you can't.  The only real options
are afunction(0,AF_NOTEQUAL) (don't draw 0-alpha pixels) and
afunction(0,ALWAYS) (the default).


Thanks a million-lighted-z-buffered-textured-polygons-per-second,

I'd like to be able to average images that consist of the density plots.   
Imagine a bunch of density plots (x-ray images for example) that contain an  
object (a bone for example), and I want to average a whole bunch of images to  
get the spatial density distribution of the "average bone".  

What I really need is some good image warping software that will allow me to  
play with the images and get them all to look the same size and shape.  Then I  
can cut the area of interest out of all the images, and simply average the  
pixels numerically.  I could do all this fairly easily if I had the image  
warping software.  Is there some public domain software out there for the SGI  
machine that will do what I need?

Please respond by e-mail.

Subject: Indigo XS24 Sphere library z-buffering problems

Hi, a program I am developing which uses the sphere library runs just
fine on an IRIS 4D/220 VGS, but when I run it on a nearby Indigo XS24,
the SPH_HEMI seems to get set true by default with SPH_ORIENT set to
FALSE (It draws hemispheres which show up as you rotate objects on
the screen).  If I set SPH_HEMI and SPH_ORIENT to TRUE, this problem
goes away, but then z-buffering goes away too and the appearance of
spheres on the screen is as if they all have the same z-coordinate
and appear in the order in which they are drawn...  The Indigo is
running 4.0.5 and zbuffer is most definitely set to TRUE...

Oh, one more thing, this is in a GLX widget that this is happening...

Are you sure you have zbuffers?  Zbuffer hardware is an extra
cost option with XS24 graphics, and unlike Entry graphics XS24
doesn't do software zbuffering.

If you don't know whether you have zbuffer hardware, try running
/usr/gfx/gfxinfo.  Output on a XS24z (XS with zbuffer hardware)
should look something like this:

	Graphics board 0 is "GR2" graphics.
        	Managed (":0.0") 1280x1024 
        	1 GE, 24 bitplanes, 4 auxplanes, 4 cidplanes, Z-buffer
							      ^^^^^^^^
If you do have the zbuffer hardware, spheres should draw correctly
with SPH_HEMI and SPH_ORIENT set to TRUE.

  Then Entry graphics option uses an all software z-buffer.  There is no
hardware option for this graphics board.  The XS and XS24 come without
z-buffer, and do not support hardware emulation.  If you want to do
z-buffering on them you need to buy the $2k z-buffer option, which is
real hardware.

   HELP WANTED  .....

   I am trying to use a wacom pressure tablet to drive the X pointer to be able to use this tablet into a paint system.

	In a previous IRIX version 4.0.1, I was able to attach the wacom to
the X pointer ( using the /usr/people/4Dgifts/examples/devices/input/X/setptr program ). At that time, I had problems to get pressure information ( It was not possible to attach the pointer to the tablet and at the same time, to use the wacom as an extension device ).

	I changed the OS (4.0.5C ) and now, I can't even attach the wacom to the X pointer !!!

	When I try to attach the tablet to the X Pointer, I get the following message:

X Error of failed request:  BadDevice, invalid or uninitialized input device

	My questions are:

 	- How is it possible to attach the wacom to the X pointer in 4.0.5?
	- How is it possible to change the wacom resolution without having
          to change the the wacom stream device in the kernel ?

If you are running 4.05 or later, fonts which have poscript outline files in
/usr/lib/DPS/outline/base will be scaled correctly with fmscalefont.


From 4.05 Release Notes (EOE #12 Fonts)

          o In previous releases, the IRIS FM used only bitmap font
            files.  The IRIS FM now uses bitmap font files, outline
            font files in the Adobe Type 1 format, or both for a
            given typeface.  The IRIS FM scales a bitmap font when
            it cannot use an outline font and it cannot find a
            bitmap font of the right size.  The IRIS FM looks for
            Type 1 outline fonts in the directory
            /usr/lib/DPS/outline/base.

That's the problem...  I was going by the graphics programming manual's
statement about software z-buffering...

So given that I do not have z-buffering on this machine, how does it run
programs like flight and battlezone without screwing up the graphics?
Do they just sort objects by depth before they are drawn?

Try:
logicop(LO_XOR);

As is usually the case with useful functions like logicop and pixmode
some machines just dont support it.  The Indigo is okay though.


[From logicop(3G)]

     This routine does not function on IRIS-4D B and G models, nor does it
     function on early serial numbers of the Personal Iris.  Use gversion to
     determine which type you have.

     Some IRIS-4D GT and GTX models do support this routine.  Use getgdesc to
     determine if logicop is supported.

BUGS
     Personal Iris models do not support logical operations in combination
     with non-solid patterns nor with zoomed pixel writes or copies.  When
     either of these features is selected, the default logical operation,
     LO_SRC, will be used regardless of the value passed to logicop.



Question:
Once OpenGL is implemented will more of these functions be supported
for ALL machines, or are the old GT's just gonna have to use old software?

I'm trying to use a 4D/35 Iris running under Irix 4.0.5 to generate an
out-of-window display for a flight simulator.  I'm having trouble trying
to relate the angles that define the aircraft's orientation with the
parameters of the "lookat" command.  Specifically, there's an argument
to lookat called "twist" that defines the angle of twist about the line
of sight.  I haven't for the life of me been able to figure out what
this variable really is, and how it relates to other variables I do know.
Does anybody out there have any experience using this command?  Any help
would be appreciated.

Thanks!
