vis5d-users Mailing List for Vis5d+

Dear Sir,

I would like to know to us the netcdf file with the vis5d+. The vis5d is
support for netcdf file format, but it is not more information.

This is my netcdf file.

Hi, 

  I am trying to install Vis5d IN WINDOWS. I am trying to install it in
Cygwin. Is there any other way to do it? Any body has any idea? I have no
idea how to start. 

Thanks. 


Best regards, 

Zhe Chen

Hi , 

Sorry for mass-mailing this basic enquiry on this list, as I hope to get more details from anyone of you in the mailing list. 

Can Vis5D be successfully built on a Pentium PC running on Win98/XP OS without any 3D Graphics Card? If yes, appreciate
if you could kindly share your experience on the essential requirements. Any comments are appreciated. 

Much thanks,

Vaidya,

Some background:

Out-of-the box, vis5d does not support files which are > 2 GB in
a 32 bit operating system with 32 bit integers. Some operating
system/compiler combinations can make "int" be 64 bits and it will work
fine, but I could not find a way to tell gcc on Linux to treat ints as
64 bits.

The v5dstruct structure has the following integers which are used to
navigate through a vis5d file:

  int CurPos;              /* current position of file pointer */
  int FirstGridPos;        /* position of first grid in file */
  int GridSize[MAXVARS];   /* size of each grid */
  int SumGridSizes;        /* sum of GridSize[0..NumVars-1] */

When the size of the vis5d file exceeds 2^31 bytes (2 GB), there is an
overflow in CurPos and probably SumGridSizes. I found this out while
trying to write a large vis5d file.

My patch does the following: changes "int" to "int64_t" in variables
which refer to positioning within a vis5d file.

How to compile using my patch:

Take the patch which was attached to the file you quoted and put it in
the src directory. Type

patch < patch64

and it will modify some files.

You must then set the following envrinment variables which will be
passed to gcc during compilation. If you are using the bash shell the
command is:

export CFLAGS="-D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE"

If you are in some csh derivative it's

setenv CFLAGS "-D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE"

Then, type configure and make.

You can then link with v5d.o and binio.o in your program which creates
vis5d files if you want to create > 2 GB files, and of course the vis5d
binary you created can read them.

I'm pretty sure that the vis5d binary that you create using my method
will be able to read vis5d files which are made using the default source
code, but I can't be 100% sure. I know it doesn't work the other way
around! What will happen if you run the default vis5d with one of my
large files is once you get 2 GB into the file all the isosurfaces and
contours get all messed up.

I have sent my patch to the vis5d list but I don't think there is any
development going on right now. There may be a "better way" to make
vis5d work with these large files, but I think my way is sound.

Incidentally, just to make sure, you have to be using a filesystem that
supports > 2 GB files, such as ext3 or reiserfs... ext2 does not. Most
modern Linux distros come with these filesystems, and I would strongly
recommend that you use either on on all of your main partitoins.

Thanks Leigh. Vaidya will look into it and let you know how it goes.

Dear vis5d users,

Hello, I am a research engineer in Japan.
I use Vis5d and have a question about vis5d scripting.

I want to use the following command.
----------------------------------------------------------
vis5d_get_time_stamp context timestep 
Returns the date and time associated with the given timestep as a list of two elements: 
{YYDDD HHMMSS}. Timestep 0 is the first timestep. 
----------------------------------------------------------

But, when I use it, date and time is output in the following style.

day - date of the timestep in days since 1/1/1900 
time - time of the timestep in seconds since midnight

How should I do to output [YYDDD HHMMSS] ?
And is it possible to output [YY], [DDD], and [HHMMSS] individually ?

Thank you.

Sincerely,
Tomohiro Hara

Hello,

We installed vis5d 5.2 on sun and it's running but I have a problem.
Suppose I run vis5d with 2 data sets: dataset1 and dataset2. I have 2
dispaly windows open and could plot any variables from each data set on
corresponding display. If I try to assign dataset2 to display1, where
dataset1 already assigned, and  try to plot dataset2 on display1 I have
an error message "Segmentation fault". It's happend only if I try to
plot dataset2 on display1. Dataset1 plotted OK on dispaly1 when both
datasets assigned to dispaly1. What would you suggest in this case?

Sincerely,

Irene

Dumb, but I noticed using X-win32 5.4 that I had to check the box to 
enable GLX buffering, I couldnt recall previously doing that. (is the 
box checked?)

Just FYI.
I've had similar problems with vis5d+ and reverted to 5.2.
I did some experiments and found that Hummingbird Exceed 7.0 (PC X
server) can handle vis5d+ but not X-Win32 5.4.  X-Win32 5.4 could
display vis5d-5.2.  (We couldn't justify spending $$$$$$$ on Exceed, so
stuck with XWin32.)

Hello,

While trying to run vis5d+ I got error message:
Xlib:  extension "GLX" missing on display "sushi:0.0".
Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

Is anybody out there know what's going on?
The vis5d+ is installed on sun and I'm accessing it from PC X-server.
I didn't have this problem with vis5d 5.0-5.2. Please help!

The Reverse Button in my Vis5d software does not work properly.... Any idea 
taht help me to fix this?

PD: I am running the Vis5d+ version of vis5d
