Hi Stuart, One appraoch is to use DelaunayCustom.fill() and related methods, which take 2-D polygons described by Gridded2DSets and return fills as sets of triangles described by Irregular2DSets. These VisAD data objects can then be linked to Displays for filled display. There are examples in some visad/bom main() methods. Good luck, Bill p.s., on the road and pressed for time On Wed, 11 May 2005, Stuart Wier wrote: > For a java package to extend the IDV I wish to make a subclass of the IDV's > MetSymbol > that draws a symbol in the z=0 plane that is filled and has more than 4 > vertices.
