This probably depends on Vis5D version and machine configuration.
Try Vis5d+ if you are not already.

Bill

Hello Bill,

Pressing SAVE button on control panel always cause segmentation fault,
so I can't save my setting in vis5d. Is it a known bug which might be
already fixed? What would you suggest in this case? 

Sincerely,

Irene

Where can i find documentation (Instructions) about Vis5d+ installation?

...

Well, relatively cheap...

See http://www.evl.uic.edu/cavern/agave/vis5d for a description of how
to get vis5d to work with a GeoWall ( http://www.geowall.org ) which is
sort of like an immersadesk only using off-the-shelf hardware.

I will be building a GeoWall this summer at Central Michigan University
and expect to use vis5d as a teaching tool in the classroom. Students
get to weare nerdy goggles, that ought to be a plus. Seriously, this is
something that I think some of you may find worth checking out.

You can build a GeoWall, which consists of two data projectors, a
computer with a certain kind of graphics card, and a special projection
screen that preserves polarization, for around $10,000.

I have not yet seen one of these in action but I am told the stereo effect
is on line with the stereo IMAX movies, and uses the same basic technology.

I think the source of the Vis5D map projections was a
manual from the USGS.

PoleRow and PoleCol are just what it says in the
README, that you quoted below: the location of
the north or south pole in your grid coordinates.
These map projections are a mess. Don't expect
any easy answers.

Hello,

In user's guide 3.2 Map Projection chapter you have an example of
Lambert conformal projection for Wisconsin
(http://vis5d.sourceforge.net/doc/ch03sec2.html). How PoleRow and
PoleCol are calculated in your example, please refer me to corresponding
source. 

Sincerely,

Irene

Lambert conformal
This is a conic projection defined by the following six parameters.
Lat1, Lat2:  First and second standard latitudes in the range
[-90S,90N]. Lat1 and Lat2 define where the imaginary cone intersects the
sphere of the Earth. Lat1 and Lat2 must have the same sign, that is,
they must both be positive or both negative. Also, Lat1 must be greater
than or equal to Lat2. 
PoleRow, PoleCol:  These parameters indicate the position of the north
or south pole with respect to the 3-D grid coordinate system. These
values may be outside the 3-D grid. If Lat1 and Lat2 are positive, the
north pole is assumed, else, the south pole is assumed. 
CentLon:  Central longitude: this parameter indicates which Earth
longitude is to be parallel to the 3-D grid columns. 
ColInc:  Increment (spacing) between grid columns at the central
longitude and standard latitudes, in km. This parameter controls the
scale of the projection. 

Example 1: Suppose your 3-D grid has 35 rows and 40 columns and you want
a Lambert conformal projection of the United States centered over
Wisconsin: 

Lat1 = 70.0 Lat2 = 20.0 PoleRow = -35.0 PoleCol = 20.0 Central Longitude
= 90.0 ColInc = 100.0

Hi,
 
If there is any WindowsXP version of vis5d or vis5d+ is available.
 
Thanks,

Hi Jeff,

Vis5D doesn't use a vertical grid where z spacing varies
in x and y, except in generic coordinates where topography
is wrong (the vertical levels are still displayed as flat).

The irregular data are for point obs, not grids.

Our VisAD system can handle vertical grids where z spacing
varies with x and y. It doesn't have the same performance
or nice GUI of VisAD, but is getting there via Unidata's
IDV.

Cheers,
Bill

Hello,

I plan on using Vis5d to visualize model output from ARPS.  The model 
incorporates a terrain following vertical coordinate, z, which is used 
as the vertical coordinate in Vis5d.  However, this presents a problem 
since the terrain following surface is not flat, but it is plotted as 
such.  Overlaying the terrain on top of the model output fields causes 
data to be plotted below ground is areas where the terrain height > 0 
(because the terrain data file uses heights above MSL, zp, not a terrain 
following grid (z) ).  I plan on fixing this problem by reading in the 
v5d file output by the model, then converting the vertical grid back to 
actual height and creating a new v5d file.  Is this the easiest way to 
do this?  Any suggestions on how to do this?

Also, a related question:  Can Vis5d use a vertical grid such that the 
spacing between vertical levels varies in x and y?  (i.e. delta z = 
f(x,y) )?  The vertical grid section in the readme file implies that I 
can't.  However, the readme document also mentions an irregular data 
type called a "record."  I'm wondering if I could possibly display these 
data that way.

Thank you for any suggestions.

Victor, 

About 1 year ago I changed jobs and much to my disappointment, I had to give 
up my continuation of development of vis5d+.  vis5d+ really needs a champion 
to lead in continuing development.  I am sure that what you see is a memory 
access to an unallocated array.  If you could take that further step and 
find and correct the problem it would be a welcomed service to the entire 
vis5d community.

Hi,

I'm an old Vis5d user (nearly 7 years of use) and I'm now trying to
migrate to the vis5d+ versions. I've downloaded the 1.2.1 and 1.3.0-beta
packages and they "configures", and installs very well on my Linux
RedHat8 with Nvidia OpenGL drivers (Linux 2.4.18-18.8.0smp).

The thing is that I'm used to work with several (2 or 3) v5d files
(contexts) and I use to "Group" them and put several contexts in the
same DISPLAY. Now, I get a Segmentation fault when I try to "Group"
displays (in particular when I click on the second display I want to
group). It may be of interest that I don't get the error when I open the
same file on the two displays (or contexts), only when I open different
v5d files. I also get a segmentation fault when I try to put 2 contexts
on 1 DISPLAY (through the DISPLAY buttonn at the main Vis5d+ GUI). In
this case, even with the same v5d file opened in both DISPLAYs, I get
the Segmentation fault.

Another issue is the userfuncs/externf settings in vis5d+ on Linux
machines. I know the libmain.a  was used in the old Vis5d release but
now it looks like the external functions need it but it is not built any
more. How can we compile external functions under Linux?

Last thing referrs to a DATE recognition problem of vis5d when loading a 
single-timestep files. When I open a file with only one timestep the 
vis5d (I've noticed it in versions vis5d-1.2, vis5d+1.1, vis5d+1.2.1) 
does not recognize the date and shows 000000 190000 instead of the 
correct time and date. The header of the file is correct because when I 
append it to another file (so building a multiple timesteps file), the 
time and date are well recognized by vis5d. Have you noticed the same? 
Have you got a patch for this bug?


Sorry if these problems have already been reported to the Vis5d lists.
I'm trying to access to the Vis5d+ users list to see if someone has also
found that but I get a "permission denied" error from the Source Forge
page. I'm registered to both (devel and user) lists and to Source Forge
also. I can  access the Vis5d+ devel list but I can't read the past
messages of the Vis5d+ user  list.


Thanks a lot!

Victor.

	Do you have any help/advise to give me? Thanks in advance.

We have a conversion program that convert our raw data files to 
v5d format.

It works very well except for the date/time stamps which are messed up, 

I tried using v5dedit to fix the datestamp but it didn't work. 
The most it did was change to datestamp to "00000". 

probably that's why I am having trouble using vis5d_get_ctx_time_stamp.


Funny thing is, on v5d display window the clock shows the right time. 

I appreciate any suggestion, I really need to get my script working


thanks

Has anyone ever tried to view, say, 6 different wind vector plots
simultaneously on multiple windows in one vis5d display?

e.g.:

vis5d a.v5d -wind2 u_a v_a \
      b.v5d -wind2 u_b v_b \
      c.v5d -wind2 u_c v_c \
      d.v5d -wind2 u_d v_d \
      e.v5d -wind2 u_e v_e \
      f.v5d -wind2 u_f v_f 

The manual seems to imply that the above should work, but
I can't seem to get what I want.  Any ideas?  Workarounds?
I'm using vis5d-5.2 on Irix 6.5.

Thanks for any suggestions or pointers.

hi,

Iam working on vis5d+ from EVL at UIC., and would like to enable stereo on that,. 

Is it enough if I run 

 src/vis5d+ *.v5d -projection stereo 

to get the stereo or is there anything else to do.  (I have installed the nvidia graphics card and is in clone mode, which i persume supports stereo.) 

When I run the file as indicated above two identical windows open on the two screens and not stereo .

Please help me. on this..

regards

vaidya.

Hi all,

until recently I was running vis5d+-1.3.0-beta under OS X 10.2.3 with 
no problems (though I had some minor trouble with the build).  I was 
using Xdarwin and Xfree86 installed via fink.  All was well.

I recently decided to give Apple's version of X11 a try.  It's still 
in beta, so I expected possible problems, and I found them.

After I installed Apple's X11 User and X11 SDK packages, I found that 
I could no longer view data with vis5d.  I rebuilt it, but that made 
no difference.  The program runs, and the control windows (with 
buttons, scales, etc) work fine, but the 3-D display window just 
shows garbage. This garbage appears to be thin lines grabbed from the 
main display, and it doesn't change, even when something is done 
which should change the view.

I posted a question to Apple's X11 user's mailing list, and received 
a suggestion to try an unusual recipe of actions.  It didn't work 
exactly the same for me, but I did find that when I use a 1x2 display 
matrix (chosen from the DISPLAY button in the control panel) then it 
clears up, and I can view things normally.  If I switch back to 1x1, 
then I get garbage again.

Any ideas?  Configuration flags, etc?  According to Apple's 
ReadMe.rtf,  "OpenGL offscreen rendering is not yet supported." 
Could that be an issue here?  It would be nice to figure this out, 
then I could submit a bug report to Apple to see about clearing it 
up.  Other than this their X11 implementation is rather nice.

Thanks,
Mike

Hi Bill,

Follow your README Vis5D version 5.1 Customizing 2.4 to change
topography file. 
1. First way to edit src/vis5d.h. There is no file with such name, there
are 2 files in src/ v5d.h and v5df.h, both files doesn't have a TOPOFILE
entry.
2. Try the other way, press DISPLAY and OPTIONS buttons, the form
OPTIONS shows up but to long to fit the screen, the bottom of the form
is cut off, anyway, I try to change the file name for my topo file in
corresponding text box but there is no way to save it, closing the form
causes exit for vis5d application. Please help with the problem.

Sincerely,

Irene

Hi,
	I have a problem when trying to use v5dwrite() function in C.
	I have declare the following:

Numtimes = 10
Numvars = 3 { x, y, z }
etc.

	And I have the following data

Time	var	x	y	z
1	1	10	10	10
1	2	20	20	20
1	3	30	30	30
1	4	40	40	40
   .
   .
   .
1	n	n*10	n*10	n*10
   .
   .
   .
10	n	n*10	n*10	n*10

	So I have the following code that fails:

	...
	float data[3] { 10, 10, 10 };
	int time = 1;
	int var = 1;
	v5dwrite( time, var, data ); ---> here I get a segmentation fault

	...


	Can you help me? Thanks in advance.

You need to make sure you have the GL headers, etcetera.  If you are using
Apple's new X11 implementation, I suspect that you have to install the
"SDK" separately.

Has anyone had success installing vis5d+ on a Mac running OS 10.2.3?  
I've recently switched from RedHat Linux and haven't quite figured out 
some software installation issues.  In this case, "configure" complains 
that it can't find any 3D graphics library.  I know OpenGL is 
installed, but am not sure how to include it.  BTW, I used the
