Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

I'm not sure what you mean by "regular order", but Gridded2DSet can handle points that are not on an evenly-spaced lattice: it's only necessary that their TOPOLOGY be a regular (i.e. square) lattice. If the topology of your points do not form a regular lattice, then you could use Irregular2DSet. The VisAD subsystems will triangulate the points as necessary. There are examples of Irregular2DSet in the examples subdirectory. Regards, Steve Emmerson <http://www.unidata.ucar.edu>
