Hi Laurent,

As I understand it, if you're using an "unstructured grid" model, with vertices
and a connectivity list, that is exactly what IDLgrPolygon and the Polygon
function work with. Whether your grid has only (x,y) position data or (x,y,z),
IDL has good tools for working with this. Depending on what you want to do,
associating the other properties can be done in different ways. With a little
more detail (Is your mesh 2-D or 3-D? What kind of display of your other
properties are you looking for?), I can offer some suggestions.
