Hi, as OpenDX beginner I am not yet very comfortable with its data model, and hoped to get some advice from this list to get me started on a visualization task.
I would like to present line-dependent data as a tube with its diameter varying as a function of one data component, and the color varying as the function of another data component. In the future I'd also like to go from simple spherical tube crosssections to elliptical ones. For the above purpose I want to add some code to the program that calculates the actual data in order to create a netCDF datafile that will be appropriate for subsequent visualization in OpenDX. As far as I got now, I will have to provide positions and connections for the line and then the different datasets along this line of which I want to be able to choose one for the radii, another one for the color. Now for example concerning the positions for the line, I don't know what's best for OpenDX, eg separate variables for x, y, z coordinates or one "points" field. There are similar other basic questions for connections, etc. So are there examples of a data model for line data available ? Any pointers to helpful examples/documentation would be greatly appreciated.
