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.
