Hello, I am a graduate student looking at various visualization systems to use for my masters project. I'm looking to see if these systems will allow me to do a few things.
Basically, I want to create my own modules to extend the visual programming language. I would like to create "choice" modules that would be connected to a number of databases. There could be many "choice" modules, each would connect to databases of different types of data sets. These "choice" modules would all connect to a single "logic" module, that allow for various operations on the different data sets. More importantly, it would give the ability to cycle through a series of these data sets. One possibility would be for it to cycle through each data set and changing the display accordingly. I am looking for more information about the VPL and extending the modules. I've found sources about creating custom modules but there seems to be some issues with these and what I'm trying to do. The modules are pure function without states, right? To cycle through the databases I would need some way to remember which data sets have and haven't been displayed. Or a way to communicate between the "logic" module and the many "choice" modules to retrieve the correct data set. Right now, I'm trying to figure out if the Opendx modules have this capability. Also, does any one know of any good references related to what I'm trying to do? What about other free visualization systems with a VPL? Any feedback would be greatly appreciated. Thanks, Tony Neumann
