vis5d-users Mailing List for Vis5d+

The sounding window does not display the vertical axis and the data when the
model top exceeds 21 km altitude. I use a vertical scale with a constant
level spacing. The vis5d fields are formed from the fields output from a
non-hydrostatic model (RAMS), and I can vary the level spacing and number of
levels as desired. The error is not dependent upon the level spacing or
number of vertical levels, but occurs when the model top exceeds app. 21 km.

I use vis5d-5.1  installed at a Linux-PC with Redhat 6.0.

The error is not present using vis5d-5.0 installed at an SGI O2 station.

Sincerely, Ib Steen.

Have you tried compiling a more recent version than 5.1?  e.g. the one
from vis5d.sourceforge.net?  I know that I fixed several such problems on
the Alpha already (I think that all of the fixes were in 5.2 as well).

After installing Vis5D on my Linux-Alpha machine, I tried to test out the program using one of the sample v5d data files. No matter which one I try, the window briefly opens, then closes and I get the following error:
	floating exception

Has anyone experienced this?? Several particulars:

* Running Red Hat 7.0 for alpha
* Vis5D 5.1
* I have tried the pre-built executable for DEC alpha - same error
* I built Vis5D from the source code - experienced NO errors - still get same error
* I can start up the GUI by typing "vis5d -nofile" and it starts up fine
* I have tried multiple data files:
	src/vis5d hole.v5d -path src  (before installing)
	vis5d LAMPS.v5d  (after installing)

Any help would be appreciated.

Thanks
Wade

All,
  This may be a little off the subject, but keep in mind, if you didn't
already know, that nVidia is the group who bought out the 3Dfx folks.  I
have hopes they will keep up the 3Dfx drivers, specifically for the legacy
applications.

Neil,

I don't have any vis5d specific info but check out these sight's  for
general comments about nvidia cards and linux.

http://www.linuxgames.com/articles/nvidia_first_look/

http://lhd.datapower.com/db/searchproduct.cgi?_catid=8

http://lhd.datapower.com/db/dispproduct.php3?DISP?2256

It pays to be very cautious when making your hardware purchase, you need
to make sure that each component of the hardware is linux compatible,
and in the case of graphics drivers there are several levels of
compatibility.

Please someone correct me if I'm wrong, but I don't think vis5d takes
any advantage of graphics hardware directly.  Only the underlying OpenGL
layer does.

Good Luck,
Jim

Here in Chile, we used the data available from the GLOBE project
(http://www.ngdc.noaa.gov/seg/topo/globeget.shtml)

We had little problem with the translation of the data into the vis5d
format.

I don't remember the routine that we wrote but it was not difficult
starting from a routine
already on vis5d (I don't remember the name also :-(

Good luck

Is there a utility available to process CALMET output (I'm running Version
5.2, Level 000602a 8/2000 ) into VIS5d input (I'm running 5.2)?
CALMET is available at http://www.src.com/calpuff/calpuff1.htm

Dear Christopher,

I made the same experience with our SGI Onyx2 IR (Irix6.5). The bug has
somehow to do with the optimization of the routine proj.c.
If you recompile proj.c with the flag "-O1" instead of "-O2" or "-O3"
and then rebuild vis5d the bug should not occur.
Best Regards,
Michael

Hi,

I have installed VIS5D on an SGI machine (32 bit architecture, IRIX 6.5) and have tested out the examples (LAMPS.v5d and SCHL.v5d) and have had some problems with spikes in the surfaces of these pictures. 

I then used a utility from NCAR to reformat MM5 data into VIS5D format and plotted the MM5 data in VIS5D.  The surface spike problem is even worse with MM5 data as shown in the attachment (gif).  In the MM5 view the picture is looking towards the Southeast US and FL.  The problem seems to be worse over water than land with MM5, but I still do get random occurrences of spikes on land too (especially near the edge).  Upon further investigation it seems the spikes appear randomly, yet the height of the spikes always seem to be half of the height of the VIS5D box used in viewing and rotating the data.

Has anyone ever encountered this problem before?  I am wondering if its an installation problem, an Open GL problem, or a source code problem?

Thanks for your time,

Chris Champagne

I've encountered the following problem attempting to save an image in
various formats using the Save Pic button via ImageMagick:

Using Image Magick convert program.
Executing: ./util/convert tmp.xwd ps:/usr/tmp/Vis5D_image.ps
convert: xwd file format version mismatch (tmp.xwd) [No such file or
directory].
convert: missing an image file name.
Done writing image file.
Executing lpr /usr/tmp/Vis5D_image.ps
warning - cannot open file '/usr/tmp/Vis5D_image.ps', No such file or
directory

The only option that work is xwd (X Window Dump). I'm running Linux7 and
its configuration doesn't  have a "/usr/tmp/" directory. Do I need to
create one? Also, I'm not clear on how and where tmp.xwd is created
and/or if it is supposed to reside in the directory "./util" which has
the convert program or somewhere else. Any help is greatly appreciated.

oh, yes. I get a similar problem when I try to print an image directly
from Vis5D...
Warning - Cannot open file '/usr/tmp/Vis5D_image.ps', No such file or
directory
hp4500: nothing to print

Hi,

I am a researcher at Illinois State Water Survey.  I used VIS5D to view a 
dataset of 2D gridded model output of the concentration of chemical 
species.  When in VIS5D,  first, I chose 'map' to be appeared.  When I 
selected the horizontal color contour for a chemical species, the map 
sometime disappeared depend on the domain selected.  How can I make MAP 
always on top of other displays (in 2D)?

I have an overall dataset of 79x51 grids for 48 variables.  When I select 
all data points the map would disappear when the color contour is 
selected.   So I experimented different size of domain area and found

test 1:
domain size from 79x51 to 40x51  --> color contour is 'on' without map
domain size at 39x51                      --> color contour is 'on' with map

test 2:
domain size > 29x26   --> color contour is 'on' with map
domain size at 28x26  --> color contour is 'on' without map

It seems like only within a range of number will the map stay appeared.  It 
will disappear when the total number of data points is either too large or 
too small.

I have try to increase the memory size using -mbs 500, but it still not 
working.  We a have 1GB RAM in our SUN workstation so I believe plenty of 
RAM is available (at least >128MB).  If you have solution on this, please 
let me know.

Thank you for your help.

Hi Josh,

1. start Xwin32
2. in a MSDOS shell type 'set DISPLAY yourlocalhostname:0.0'
3. type 'vis5d small.v5d' (vis5d.exe must be in your PATH or
     in the same directory)

At least this works for me (WinNT4.0). But the speed is disappointing.
It renders everything in software.

Best Regards and good luck
Michael

Dear Chris,
	the first idea that comes to my mind is you could have forgotten
the assignment CFLAGS = -DLITTLE in the makefile for compiling c sources,
since Intel-like machines have "little endian" byte ordering, as opposed
to SGI; you could also verify this with the command
 od -a <myfile.v5d>|more
if the first bytes on the file are something like " D5V" instead of "V5D ",
that's the problem.
	I hope this helps,
		Davide

I'm having a problem.  I modified foo_to_v5d.c to read GMT grid files
(really netCDF files) to create a v5d file.

It runs great on my SGI machine, but when I give it to a friend running
Linux (RH7) it doesn't work in the following way:

We got it to compile and run (after hunting down a rouge fclose(f)).  And
it creates a file, but vis5d and v5dinfo don't recognize it.

Error: not a v5d file

Frustrating, because it compiles and runs without errors.  And it
compiles, runs, and gives good data files on my SGI.  I'm not up on
Linux... anyone have trouble Creating v5d in Linux?  We're using g++ (and
the netCDF c++ libraries, but they seem to be reading the files just fine

Subject: Sounding display using oceanographic data


Hello,

I have been writing some code to convert netcdf oceanographic data
(temp, salinity) to vis5d format.. My code compiles and the data shows
nicely in the 3d window.. However, when I am using the sounding display,
the temperature/salinity profiles look okay as long as I convert the
full data set (down to 5000 meters) but, when I try to look at near
surface 0m to 500m for example, the profiles in the sounding display do
not adjust correctly, the profiles aren't visible... my vertical setting
is 2 for none equal spacing (Km).. I have even changed the code in vis5d
to indicate that it is oceanonly.. but still have the same results.. Any
suggestions??

Thanks
