Thanks a lot Jeff!
I was also wondering: any chance to provide a Windows64 port of GDA's threaded 64-bit version?
I have been able to compile it from source under cygwin64, but it may be even more handy to have a truly native version (MSVC, MinGW64 or something).
Unfortunately, I have been unable to compile a native Motif library with MinGW64.
 
Anything new about this version (GDA) btw?
I use it a lot with almost no annoyance, except it doesn't seem to work at all with GetGlobal/SetGlobal constructs.
Maybe something wrong with the new cache management: I have tried to look into the getset code but my skills are very limited and I could not find out.

5  OpenDX Users / General Usage and Troubleshooting / rectangular to cylindrical warped grid
 on: 11/11/13 at 03:33:02 
Started by les | Post by les
Hi All,
 
I am visualising measurements from a cylindrical duct. I used the method detailed in the WarpedGrid.net example. An image is produced but contains the following errors:
1. In my rectangular grid the y coordinate points start at 1.9 m and not 0 m. This creates a region which is not interpolated in the centre of the image. Please advise what modules do I use to ensure this region is interpolated?
2. The warped grid image produces edges on the circumference. I would like it to be completely circular. I assume this can be done with an OpenDX module. Any advice would be appreciated.
 
Many thanks,
Les

Unfortunately, the website links have been dead for some time, but you can find a recent source RPM package here :
 
http://download.opensuse.org/source/distribution/12.3/repo/non-oss/suse/src/dx-4 .4.4-241.1.6.src.rpm
 
Unpack it with the following command :
 
Code:
rpm2cpo dx-4.4.4-241.1.6.src.rpm | cpio -idmv 


 
It contains tar+bzip2 packages of the source tree and samples.
It also contains patches to help it compile on recent Linux distros.
 
Alternatively, if you want bleeding edge, you can have a look there :
http://www.opendx.org/cgi-bin/forum/YaBB.pl?num=1256241737
Or perhaps also there :
http://opendx-gtk.sourceforge.net/

Depends what "issues" you are referring to.
Specifically on data formatting issues, I think the HTML manuals are your best source of information.
It is really not bad at all: with Firefox, open (and bookmark) the "allguide.htm" in the "html" subfolder.
There is even a comfortable search tool.
You may start with those "must-reads":
 
Index => User's Guide => Chapter 3 - Understanding the Data Model
                                          (and more specifically => 3.2 - Object Types => Arrays)
 
                              => Appendix B - Importing Data: File Formats => B.2 - Data Explorer Native Files
 
The "Compute" module is also extremely powerful, so you should definitely read its documentation page:
 
Index => User's Reference => Chapter 1 - Data Explorer Tools => Transformation => Compute
 
Of course there is also the well-known book "paths to visualization" which is highly advisable.
 
Note: although there is nothing fundamentally wrong in putting all your data columns in a single big multi-column "data" component, and extracting the appropriate column(s) with a "Compute" as in my previous post, the DX "field" structure is actually rather meant to group all different kinds of data into separate "data" components, which can later make it easier (more flexible, and more straightforward) to select a given kind of data at a given spot in your visual program.
 
A "field" can have any number of data components, which can be either "position-" or "connection-" -dependent, which can be scalar (single-column, rank 0), n-D vectors (n-column, rank 1) or n-D tensors (n x n -column, rank 2), and which can be expicitly named after their content (not necessarily the default name "data", but can also be "pressure", "gradient", "vorticity", "electric field", "strain tensor"...).
 
You can then "Import" only the data component you need (using the "variable" argument to the "Import" module), hence save some memory by not loading the other data components, or use the "Mark" module, like Mark("pressure") or Mark("gradient"), to select which actual data component you want to operate on with the tools downstream in the network ("Compute", "Statistics", "Autoglyph", "Rubbersheet", "Isosurface" or "Autocolor" or whatever).
 
It is then common practice to feed the component-name ("string") input to the "Import" or "Mark" modules from the "name" output (also "string") of a "Selector" interactor, which allows you to interactively select the data component you want by selecting its name in a control panel: you don't need to remember which column is which variable or create lookup tables for assigning explicit variable names to your data columns.
 
BTW, you should carefully read the documentation of the "Mark" and "Unmark" modules, especially to notice that the "Unmark" module can be used to create a backup of a component before applying modifications to it, allowing you to restore the original downstream by "Mark"-ing the component name you specified as the backup.
 
Index => User's Reference => Chapter 1 - Data Explorer Tools => Structuring => Mark / Unmark
