Hi John, You'd have to construct your river system or circle as VisAD Sets with domain dimension = 2 and manifold dimension = 1. There are constructors for Gridded2DSet that do this. For a set of line segments, you'll need to construct a UnionSet of a bunch of Gridded2DSets, each with manifold dimension =1. Please let me know if you have further questions or problems. Cheers, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
