You can do it by editing src/render.c to put your own drawing
logic inside the fucntion draw_user_3d_graphics(). At least
in Vis5D version 5.1, there are some nice comments in there
to help you.

Good luck,
Bill

Dear all,

is there any way to plot three-dimensional
vector lines at every time step using v5d?

I'm thinking in ploting the vector lines of
the magnetic field, and so 3D is crucial here.

Thanks a lot,
Alvaro.

CBS will be trying out a new graphics technique for replays
during the Superbowl this Sunday.  You can read about it at:

  http://dev.web.cs.cmu.edu:6666/testReleases/demo/40.html

About 25 years ago, when SSEC was struggling to animate
GOES or SMS images, our founding director Verner Suomi
saw instant replays of football plays on TV. He figured
that whatever was doing that could animate his satellite
image, found out they used analog disks, and got McIDAS
to use them for the first animation workstation.

Do you mean quadralateral cells in 2-D polar coordinates,
of tetrahedral cells (i.e. 4 vertices each) in 3-D spherical
coordinates?=20

We are not experts in HDF. In any case Vis5D can only display
data with regular grids. However, our VisAD system can display
irregular data (go to the URL in my sig, and click on the
VisAD link). VisAD is for developers rather than end users,
and requires some programming in Java. Note that VisAD's
interface to HDF5 includes non-Java "native code" (C++) and
may not handle that data type you are contemplating (the HDF5
interface to VisAD was written by NCSA and I am not sure of
its exact capabilities).

Bill

Hello,

before using vis5d, i am investigating the possibility to
visualize an earth mesh made of irregular cells (all cells=20
have 4 specific polar coordinates), that contain some physical
parameter values.

From HDF5 user's guide
(http://hdf.ncsa.uiuc.edu/HDF5/doc/Dataspaces.html)
i guess that "complex data space" may help me to represent my data,
but the manual says "Currently only scalar and simple dataspaces are=20
supported with this version of the H5S interface".

I'd like to know if i'm right in the dataspace type i should use,
and if yes are complex dataspace available today  ?
(the document is dated 14 October 1999)

Thanks.

These days I recommend "Intel" chips and Linux.  You need
enough memory for your data sets.  I recommend fast graphics
from nVidea or similar.  And a fast processor clock speed.
I have no opinion on Intel versus AMD.

What would be your dream Intel/AMD platform and OS for vis5d? And
if you couldn't have that, then what would be a second, and then 
maybe a third choice? 

And for grins, let's say in addition to the processor, Intel or AMD,
you were confined to a Unix-variant OS that would need to do NFS 
client mounts of data filesystems from SGI IRIX and Compaq True64 
(Digital Unix). You would be thinking in terms of a teaching
lab of, say, 20 such beasts, and a budget cap of say $3500-4000 each.

I would like to direct this primarily to the vis5d creators and 
its maintainors, but would also like to hear anyone's desired 
configuration based on your experiences and knowledge of the
software and its usages.

I assume that an optimum machine/OS selection would be based on
the best match of processor/chip set speed and compilers that know 
how to take best advantage of its optimization features to do the 
vis5d program tasks. Next (or firstly) might be graphics and display 
considerations with proven driver stability for the OS and hardware 
match. There are certainly more items of critical cnosideration
and I'd like to hear them, too.

As you can easily guess, I'm planning for an atmospheric sciences 
teaching lab concerned primarily with synoptic scale data analysis 
and model display and exploration. That would include the 
operational model data sets but also MM5 model explorations, too. 
That might give an idea of minimum L1,L2,RAM & VRAM.

Many thanks in advance to all who might chime in. -Neil

Hello,
thank you for your help Bill and Jim.
I have solved the problem by installing a newer Version of the Solaris
Version of OpenGL (Sun OpenGL 1.2.1 for Solaris), now the pre-compiled
version of vis5d works fine. 
Making it on my own still makes trouble, but the errors have changed (e.g.
meanwhile make can find the gl.h).
Cheers,
Wolfram

You might also try the vis5d+ distribution available from vis5d.sourceforge.net,

the configure and Makefile setup of that distribution is a little more clever
about figuring out whre things are installed.

Looks like one of three things:
1. OpenGL is not installed on your Sparc
2. OpenGL is installed incorrectly
3. Sun has moved the locations of library and includes files
   in Solaris 7.

You can either figure out what is going on with OpenGL,
or compile with 'make sunos5-x' (but this will be much
slower than using OpenGL).

Good luck,
Bill

Hello,
I have some problems with vis5d on a Sun UltraSparc 10, Solaris 7, with
OpenGL.
If I try to start the pre-compiled version (SUN Ultra / SunOS 5.x with
Creator graphics and Sun's OpenGL) I get the following error message:

Error: glXMakeCurrent failed!

And if I try to compile vis5d on my own (vis5d-5.2 and vis5d+) I get the
following errors:

"api.c", line 41: Can't find include file GL/gl.h
"api.c", line 42: Can't find include file GL/glu.h
"api.c", line 43: Can't find include file GL/glx.h

"api.c", line 5943: howmany: argument mismatch
make[2]: *** [api.o] Error 2

I have a little bit experience with 'making' vis5d on linux where it worked
better ...

Thanks, in advance,
sincerely Wolfram Ruehaak

It looks like userfuncs/externf expects there to be no
Fortran for Linux.  Perhaps someone has modified this
file to work under Linux.  If so, I'd be happy to add
their changes to our distribution.

Hi

I tried compiling the probe.f and spd3d.f.
However, I got message saying Fortran was required
I am it running from a Linux machine.
I think the flags are not set in externf.
or is it that it is not supported in Linux yet?

anyone can help???
Thanks

Vis5D does not have any functions for reading paths computed
externally, although perhaps someone has modified it to do
this?

You might be able to do what you want with an external
function. It would get the entire grid of values for each
variable, at one time step. It could then read your path
information and compute variable values along that path.
Of course, in this mode of operation Vis5D would not be
giving you any computational help.

Cheers,
Bill

  That error looks like vis5d is running on an HP system and compiled for
PEX.  In that case you want to recompile it on the HP to use OpenGL.
The OpenGL version should work better than PEX for both local and remote
display on any HP system shipped since late 1997.
