Hello,
	I can convert my data from MM5 to vis5d format but I have to
interpolate from MM5's sigma coordinate to elevations.  When I don't do the
interpolation the conversion works fine but vis5d doesn't like the fact that
the min > max value of the coordinate.  I gone through all of the options in
the manual for defining a vertical coordinate system on the command line.
Does anyone have any suggestions for overcoming this problem?

Respectfully,
Roderick Pearson M.S.

I have been trying to port the NCAR version of Vis5D4.3 (with stereo) to an
HP Visualize Center, but with minimal luck. It compiles and has
occasionally run until a button is pressed, then usually the context fails
and the system dumps. I am really interested in getting it going, but it
seems best to do it with the new 5.2 version. Let me know when you are
ready with that and I will try again.

By the way, is there an opengl equivalent to SGI_dump? That is one
reference that could not be resolved. I also received warnings about
redefining MAX and MIN, though I assume this isn't a big deal.

Thanks

greetings:

i have having trouble with the wind trajectories.

in this case, the variables are U,V, and W and these
are for ocean current components. the problem is that
when the instructions for creating trajectories are followed,
the only thing that appears is a single dot and this is the
dot created with the 2nd mouse click.

the example LAMPS.v5d that is included with the distribution
works fine, though.


the manual(4.2 page 18) says 

"For the purposes of calculating wind trajectories, Vis5D assumes
the relationship between height (H) and pressure (P) is:

P = 1012.5*e^(H/-7.2)
H = -7.2*Ln(P/1012.5)



QUESTION: do we need a pressure array of values, or
does vis5d take the height values implied below, compute
a pressure function and then create the trajectories based on
the pressure values?

the vis5d file is created with:

 v5dCreateSimple(...,northlat,latinc,westlon,loninc,bottomhgt,hgtinc)
vd5CreateSimple(..., 37.104,  0.0020, 76.134,  0.0025, -0.0500,  0.0050)

here are the heights:

    h (km)
 1  0.
 2 -0.005
 3 -0.01
 4 -0.015
 5 -0.02
 6 -0.025
 7 -0.03
 8 -0.035
 9 -0.04
10 -0.045
11 -0.05

using the formula for pressure above, one sees that the pressure
only changes by 4 units from top to bottom.

any help would be appreciated.

Hi Philip,

The description of 'v5dappend' in the vis5d README file
says that this utility "might be useful if your weather model
generates a separate .v5d file for each time step" - you can
concatenate these short files to a bigger one.
It does *not* seem to work for different variables on the same
time.
Instead I would try to use v5dimport. Just start 'v5dimport', open the
'Read File' menu. Select the first file - hit 'ok', select second
file - hit 'ok' and export all to a new file (type in the new filename
and hit the 'Make' button). This should also work for different grids.
and/or different times.
Regards,
Michael

Hello,

I have a very bizarre problem. I generate cdf data with the
fortran subroutine v5dwrite successfully. 
v5dstats confirms the extreme values and reports no missing
data. A test by writing in an ascii file confirms that
everything is normal. However, when I view this data with
vis5d 5.2, I see a big irregular hole around level 35 (out
of 50), where the data is nearly homogeneous. The probe 
confirms that there is some data here. A time step later, 
everything is normal.
My problem is perfectly reproductible.

I'm running vis5d-5.2 on an SGI IRIX64, after having compiled
it myself. Has anybody experienced this kind of difficulty ?
Would you have a clue for testing and finding out what is
wrong ?

My file is nearly 1Mb, so I did not want to attach it to the 
e-mail. But you can find a copy of this e-mail and the file
at the address

Thanks a lot,

Wow, it seems that you have quite a thriving Vis5D community here. I've
only been using Vis5D for 1-2 months, just subscribed to the list last
week, posted a question and got 7 very helpful replies right away!

Hopefully I can give something back to you all by making some
improvements to Vis5D. I'm currently fiddling a bit with the GrADS
import part of v5dimport to make it less case-sensitive and support the
"PDEF ... pse" projection mode.

Thanks again for all the helpful replies!

Hi,

We had recently encountered the dreaded GLX error on our PCs running Exceed
6.0 (with vis5D hosted by an SGI machine), and even with Exceed3D loaded in.
However, once we upgraded to Exceed 6.2 (that is, the latest version)
everything worked smoothly. So, the fine folks at Exceed must have fixed
something, that wasn't allowing proper emulation for SGI hosts. Anyway,
vis5D now operates fine and fast through our PCs running Exceed/Exceed3D

But here's the really neat part: our PCs have stereo-equipped graphics cards
installed (as of last year you could get such a card for ~$100). It turns
out we can run the *stereo* version of vis5D on our SGI, and do stereo
(shutteglass) visualization through the local network with our X-emulating
PCs. This seems the best of both worlds to me, in terms of cheap immersive
visualization.

To add to Bill & Don's replies:

I got the same response: the control panel widgets come up, and a graphics
window that stays black.  Turns out I loaded Exceed3d (the "add-on" to
Exceed) on top of an old version of Exceed.  When I uninstalled
everything, installed Exceed 6.2, and then Exceed3d it ran fine.

Well, actually one more thing: it didn't run fine, until I set the screen
resolution on my ViewSonic P815 to 1152 by 864 at 120 Hz and re-booted.
Then it ran fine, even with NCAR's -stereo setting for Crystal-Eyes
stereo.

I'm running Windows NT with a Elsa Gloria II graphics card.

Adding to Bill's comments, the Hummingbird solution really can work
quite nicely. I've run it over 100BTX from our Onyx2 to an SGI320/NT
system as well as various IBM thinkpads, all with good success. I've
observed 200K+ tris/sec sustained performance with the 320. Of course,
in this mode all of the geometry is flowing over the wire and eventually
that saturates things. I've worked on my NT box in my office on
some pretty large projects without suffering unduly (eventually
one treks to the Onyx2 console 'tho ;-). One example:

	http://www.scd.ucar.edu/vg/CAT

On very large datasets I've occasionally observed instability in the Exceed
X server but could never pin it down enough to file a report. YMMV.

David Holland reported the same problem and got the
following advice from Michael Boettinger:

  If your graphics card offer hardware accelerated OpenGL you
  may want to try out Hummingbird Exceed 3D:
  (http://www.hummingbird.com/products/nc/exceed/index.html)
  This is a commercial X-Server software with OpenGL extensions.

  First of all: it works.
  I have tried to run Vis5D on our Onyx2 with X-Display set to my
  PC (PII 400 MHz, Diamond Fire GL4000 Graphics card, 10 MBit
  Ethernet connectivity). Depending on the selection of visualization tools
  (e.g. Isosurface, Isolines,..) the responsiveness of the 3-D-display is
  not bad - but far away from anything you could get locally on the SGI.
  But it works with my setup definitely better than pure software rendering.

Here was David's response:

  I have followed your suggestions and I can now display Vis5D on my PC
  X-server.  As you suggested, I have tried the Hummingbird Exceed 3D product
  which has the OpenGL library.  That software installation got rid of the
  software error message

  Xlib:  extension "GLX" missing on display "my sgi:0.0".

  I still received the hardware error message

  Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

  So I switched to a video card with hardware OpenGL as you suggested and now
  all works fine.  The card I am using is a "64MB DDR NVIDIA GeForce2 GTS
  (Dell)" product.  Thanks for your help.

Good luck,
Bill

I know that there is a version of Vis5d that compiles under Windows, but
has anyone successfully run Vis5d on a UNIX machine but set the DISPLAY

that the X-server needs to support the GLX extensions. Under Labtam's
X-WinPro I get the same message that Jose Pereira reported:

Hello,

    I've already manage to compile vis5d 5.22 in a linux redhat.
However, when I try to run I get the error message:

Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

    Does anyone know what to do, please? Do I have to reduce to 8-bit
colors my system?

cheers

Oops.  I just took a look, and the version on our website did not have the VRML
output in it.  I just updated it.

You can get the source from:
http://www.scd.ucar.edu/vg/SoftwareSystems.html

Caveat: We have not tested this with non-SGI systems...  Look in the toplevel
Makefile to see how to build with stereo and VRML support - the irix6-n32-ncar
target is the one we normally use.

I will try and move stereo integration of 5.2 higher on my priority list...

Your data need to be organized in a regular xyz grid, not as just
a collection fo values are irregular xyz locations.

See Section 3.1 of the Vis5D README file to find out how to
put your data into Vis5D.

The folks at NCAR may have a version of Vis5D that creates VRML
scenes.

You can run Vis5D in the background via TCL scripts.  Some
folks run Vis5D from cron jobs this way.  However, you need
to have an X Display open.

Perhaps someone with more experience can give you more details.

Good luck,
Bill

I am a new user of VIS5d. I am trying to use vis5d for my finite element
data visualization which contains very simple X,Y,Z nodal coordinates and
the nodal value on each coordinate (can be nodal stress value, or
displacement, etc). I like to get the final contour plot saved in VRML
format (WRL) which i finally intend to export to my Virtual Reality
environment for final viewing. I have a couple of questions for anyone who
is well-versed with vis5d.

1. How do I start? and how can I get the final plot in VRML format?
2. Can I invoke or run vis5d in the background from command line (or using
system command from a C program for instance) to
achieve my objective? If so, how could I do it?

Thank You

I have heard from a user who wants to run Vis5D under Redhat
Linux 6.1 and X Windows 3.3.4 with a TNT M64 card?

Can anyone offer any insight into whether this will work,
or whether the X Windows version needs to be upgraded or
the TNT M64 card is appropriate?

Thank you,
Bill

Dear Michael,

I have followed your suggestions and I can now display Vis5D on my PC
X-server.  As you suggested, I have tried the Hummingbird Exceed 3D product
which has the OpenGL library.  That software installation got rid of the
software error message

Xlib:  extension "GLX" missing on display "my sgi:0.0".

I still received the hardware error message

Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

So I switched to a video card with hardware OpenGL as you suggested and now
all works fine.  The card I am using is a "64MB DDR NVIDIA GeForce2 GTS
(Dell)" product.  Thanks for your help.

Cheers, David

Are you running from an xterm?  That could explain the
problem.  Try it sitting in front of the SGI main console.

Cheers,

Hi!

I met the following situation when I executed vis5d version 5-1 on our
SGI(IRIX6.5):

Xlib:  extension "GLX" missing on display "my sgi:0.0".
Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

Anyone knows how to fix this problem?

Dear Vis5d users & developers,

I'm happy to inform you that, thanks to a contribution by Axel Reimann,
the Vis5d(+) manual has been converted to DocBook format.  From DocBook,
HTML, PDF, and other formats are easily generated, and the results are
available online:

	http://vis5d.sourceforge.net/doc/

(See also http://vis5d.sourceforge.net/ for PDF and PostScript versions.)

Also available is an updated release of Vis5d+, version 1.0.2, which
incorporates recent bugfixes as well as the new manual.

Cordially,
Steven G. Johnson
