Vis5D does volume rendering by a series of semi-transparent planes, here the choice of planes changes depending on the view direction. This technique is widely used and was first described in my own paper at the 1989 Volume Visualization Workshop at Chapel Hill.

Dear Daniel Thank you for your kind and detail reply. I wish I understood. However, I could not follow your reply because of my poor ability. Sorry. I have done a little in tcl srcipting under linux vis5d before. I am sorry to trouble you. To confirm the "tcl operation under windows vis5d", Your answeris that I can do but I need some techniques. Is is right? For the second question, can I "convert the vis5d file to other format, eg. gif, mpeg, etc" Your suggestion is I can do it using imagemagick. Is it right? I am sorry to trouble you a lot. I make my best efforts to understand what you told me in your mail.

Dear Sir Thank you for your advice on "display under window 2000". I made it. I am very happy. I have some other questions. 1. Can I use the tcl script under windows NP version? 2. How I can make other comman formats(ex. gif or pmeg) of movies by VIS5d? If I can, I display the movies of vis5d on any other computers easily. 3. Do you have any previous mailing list archives in your wave? Otherwise I will repeat the same questions to you and trouble you a lot. Thank you in advance.

Don't forget to connect the synchronization source from the "box" to IDesk though. Also, navigation in the scene will be somewhat different (by mouse, not by wand) and, more important, a notion of "driver" --a person to whom the IDesk location+orientation sensor is attached and for whom the perspective is defined in applications like CAVE5D-- is not applicable anymore. In short, IDesk becomes a big stereo screen, which is very suitable for many situations.

Dear Sir Could somebody tell me how to change deault display under window 2000? I use Netmangage XoftWare xwindow system. I downloaded v5dexe.zip und unzip it to the directory c:\vis5d I move to the directry c:\vis5d (our IP address is 202.184.30.69) Than what I did is under dos command type vis5d coads_clim.v5d -wdpy 202.184.30.69:0.0 error says "unable to open default display" How I can change the default display under window 2000.

Hello, Jeff. Thank you very much for your response. After your explanation it does make sense now. I still have a question, please. It is probably a very stupid one but...

It simply means that the OGL libraries on the system recognize that stereo is available.

Hello, I found this in release notes for Vis5d+ 1.2.0: The NCAR modifications to vis5d 5.2 have been added. - Support for stereo display mode (requires hardware support and proper configuration) ... This is exactly what I have to do - to use vis5d+ with stereo display (ImmersaDeskR2). The question is what does it mean 'proper configuration'? Please, any suggestions? Might be I overlooked something in the on-line documentation? Thank you. Respectfully, Oleg Uvarov |

Dear Oleg, I think the note you cite from vis5d instructions concerns c-shell (csh), if your shell is the korn shell (ksh) the equivalent command is ulimit -s 32000 and probably you need also to run ulimit -d X where X is something like 200000 or anyway a number allowed by your system, I wonder why OSF has such small default limits on memory. best wishes, Davide On Fri, 18 Jan 2002, Oleg Uvarov wrote: > Chapter 2.

Hello again, just want to say that the problem has been solved. Latitude of origin is either 90 or -90 degrees. PoleRow/PoleColumn has to be multiplied by columnIncrement and we get the origin of the 3D-Box in projected coords. I suggest more meaningful names for those variables :-) Thank you for reading, Antonio Bleile P.S.: Have written some C++ code for transforming lambda/phi <-> Lambert Conformal. If anybody is interested.... Go and get it from me.

Vis5d also by default allocates a fixed-size memory pool. Try passing the "-mbs 0" argument to vis5d when you launch it in order to tell it to allocate as much memory as it needs. (We'll probably change this to be the default.) On Fri, 18 Jan 2002, Oleg Uvarov wrote: > Hello, > > I have OSF1 V5.1 732 alpha.

Hi List,
I have a problem with the Lambert Conformal projection.
I have a textbook which contains all the
formulas for the forward and inverse Lambert
Conformal projection. The formulas work pretty
well, but they are parameterized in a different
manner than in Vis5D.
A Lambert Conformal projection is generally defined by:
1. The two standard parallels
2. Latitude and longitude for
the origin of the projected coordinates
A Vis5d Lambert Conformal projection is definded by:
Lambert Conformal projection:
Standard Latitude 1: 25.010000
Standard Latitude 2: 25.000000
North/South Pole Row: -126.380463
North/South Pole Column: 40.000000
Central Longitude: 95.000000
Column Increment: 81.269997 km
OK, i got the standard parallels and the central
longitude. The thing I'm missing is the latitude
of the origin.....
It must be calculated somehow with PoleRow/Column.
But I don't get it. I tried to calculate the latidude
like this: Walk ColumnIncrement*PoleRow km from the
north pole along the central logitude southwards and
calculate the longitude. But this doesn't work. (My
projected data is too much south or too much north...
but the east/west alignment seems to work....)
Please can somebody explain in some more detail the
meaning of PoleRow and PoleColumn?
The only documentation I found is this:
" 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."
So what is the 3-D grid coordinate system?
I would greatly appreciate your help.
Thanks and best regards,
Antonio Bleile

Hello, I am a novice to vis5d. I use vis5d+ v. 1.2.1 I have the following problem. I am trying to save configuration and to restore it later. So there is no problems with saving. But, when I am trying to restore, it complains: Error while reading conf.SAVE File my be corrupt or an old version Please, can somebody tell what it is all about and how to solve the problem? There is very first line in the saved file: #Vis5D 4.3 Tcl save file Is it about version of vis5d or Tcl? Vis5d+ based on vis5d v. 5.2, so... I found that at least the following lines from the saved file are illegal according to the description of Tcl scripting for vis5d: #Light map color vis5d_set_color $dtx VIS5D_LIGHT_MAP 0 1.000 1.000 1.000 1.000 #Dark map color vis5d_set_color $dtx VIS5D_DARK_MAP 0 0.000 0.000 0.000 1.000 I mean that that there are no such parameters as VIS5D_LIGHT_MAP and VIS5D_DARK_MAP. Please, any suggestions workarounds etc? Thank you. - Oleg Uvarov |

Bill;
We still use the GEMVIS program which must be linked
with GEMPAK. However, it is old and no one is supporting it.
Attached is a note from Keith Brill who put together the
current version. I will see what I can do but not
until the end of this month.

Hi, Jordan,
The latest version(s) of GEMPAK use a differenct way of including files
at
compile time. The GEMVIS link script and INCLUDE statements in the code
conform to the old way of doing things. The user needs to go through
the
code and remove all GEMINC: strings from the INCLUDE statements. Then
remove the
setup_links and remove_links commands from the link script. There may
be
other changes that need to be made too, if any calling sequences have
been
changed. EMC is very far behind in its GEMPAK builds. Unfortunately
have
zero time right now to work on it.

We have been trying to get NCEP gemvis program [the 2 Sep 1999 (final?) release] up and running but are unable to complete the installation. It is trying to find the gempak area files "setup_links" which doesn't exist anyway in our GEMPAK file area (including the original tar files containing the gempak software). It is trying to find these in the $GEMPAK/install directory which simply isn't there at all. Has anyone had recent success with this? Better still is a more up-to-date translator between gempak formats and vis5d available?

All, On the chance that someone else will make the same dumb mistake I did I thought I'd post this follow-up. I was having trouble with maketopo on an SGI platform. After launch, vis5d issued numerous "nan" messages and the topography displayed as a flat sheet. I thought this was a bug in the SGI implementation as a similar complaint was posted by another SGI user. It has nothing to do with the SGI. Here is the answer. Pay close attention to the units! The vertical scale in my 3-D volume was in kilometers. The vertical units in my topography data was meters. Use v5info to check your units and ranges. Use v5dedit to correct them if needed and use topoinfo to check your topography. Here is another tip. Your topography field can be very much larger than the horizontal domain of your volume. For many applications EARTH.TOPO will do since it covers the globe (but it doesn't have subsurface topography, ie. seafloor). I made a single topography file for the entire Gulf of Mexico. Now any subregion of the Gulf of Mexico I want to visualize will have the properly registered subregion of the bathymetry. In other words the topography doesn't have to match perfectly with the horizontal region of your volume. I know many of you already knew all this. Now it's here for posterity. Thanks to James T. Potemra for setting me on the path to the solution and to Jim Edwards for suggesting other avenues to examine.

I can view multiple slices of the same data in Cave5d - used the clone variable and the 2 vertical slices as shown below. I could turn on both slices at the same time, see them and manipulate them. I'm using Cave5d version 2.0. VAR_CLONE LST LST1 VIS5D_CVSLICE LST Sur_temp_CVSlice 259 0 259 400 1.400 1.000 0.000 128.0 VIS5D_CVSLICE LST1 Sur_temp_CVSlice 159 0 159 400 1.400 1.000 0.000 128.0 good luck, Eileen At 03:07 PM 12/21/01 +0000, Alkharobi Talal Mousa wrote: >hi every one > >I am using Cave5d and I am trying to view to view 3 slices of the same data > >one horizontal and two vertical slices > >I Was able to view 1 horizontal and 1 vertical only > >the second vertical doesn't appear even when I used clone variable > >can some one help > >thanks > > > > Eileen Rotthoff Applied Research Laboratory (ARL) Penn State University P.O.

hello Every one I am using cave5d and trying to view 2 vertical slices of the same data=20 I was able to view each slice alone but when I include both of them in = the configuration file I can see only one of them=20 I used variable clone but the same thing happen=20 any one has an idea=20 Thanks=20 |
