I'm a member of Dr. Pensak's Advanced Computer Technology Group. I'm starting my textual data mining visualization project using VisAD with a simple 3-D surface static graph from a file. The file has X values 1-40, Y values 1-30, and Z values 1-30,000. The 3-D graph should show the terrain of the Z values. Later I want to interactively update the graph by getting values from a remote server when the user clicks on a JFC table. I have VisAD working and have explored all the examples in detail. However, nothing seem to come close to what I want to do. Most values are pre-generated or come from a native interface to Fortan subroutines. My question is-- does someone have a simple example of a 3-D surface from a file (or static array) that I could use to bootstrap this project? I'm perfectly willing to figure this out on my own. However, if something similiar is out there it could save me many hours/days/weeks of work. Thanks in advance for any help.
