Re: Multiple FlatFields on a Single Display

There are many possibilities here.  You can link any number of
different FlatFields to the same DisplayImpl (each via its own
DataReferenceImpl).  With current DataRenderer implementations
(except the one done by Lutz Laemmer), all these FlatFields are
displayed independently but in the same coordinate system.  That
is, this does not allow values of one FlatField to color a
terrain defined by another FlatField.  However, you can achieve
that sort of thing by using the static method FieldImpl.combine
to merge multiple FlatFields into one (this was described in a
recent email on visad-list).

Please feel free to describe your situation in more detail, if
you'd like some help with figuring out how to proceed.
