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>
