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.

Many thanks in advance,

  Marc Baaden
