I have a field that looks like
(lat,lon,lev) --> (uwind,vwind)

I display it as vectors by mapping to Display.Flow1X and Display.Flow1Y:
    display.addMap(new ScalarMap(uwind, Display.Flow1X));
    display.addMap(new ScalarMap(vwind, Display.Flow1Y));

I also have a bit of code that gives me a VisADLineArray given a length
and direction. I imagine there is something better in VisAD that does
this so I am eagerly awaiting other responses.

Hope this helps,
Doug
