Hi Ugo,

couple of questions on the subject:

Is there a way to get javax.media.j3d.TriangleArray's from my
aforementioned Irregular2DSet? If not, how do I grab the coordinates of
a given (delaunay) triangle?

The vertex integers are indices into the samples array of
the associated IrregularSet, and the samples array values
give the coordinates.

OK.

As said, I've used the irregular set because of its triangulation
capabilities...Now I know it works, I'm trying to serialize the
object(s). Are FlatFields not serializable?

They should be. If you are getting an Exception, please
send us the stack dump with line numbers.

DataUtility is saying this:

java.io.NotSerializableException: java.lang.Object
   at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)

   at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052)
   at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)
   at visad.util.DataUtility.isSerializable(DataUtility.java:1454)


and forcing a writeObject results in this:

java.io.NotSerializableException: java.lang.Object
   at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)

   at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052)
   at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)

visad.jar is the latest.

Cheers,

Ugo

Cheers,
Bill
