I did in the meantime and I will try to create a small testcase. In the
meantime I managed to revisualize the objects in just grabbing the
geometry and putting it into a new object.
But now I have another question.
I am creating a terrain-like shape with an Irregular2DSet. What I want to
do now is give that terrain a bit of thickness. So I guess I have to do
Volume Rendering. I understand that I have to use a Linear3DSet for
VolumeRendering. In one of your messages you mentioned that it is possible
to resample other fields into a Linear3DSet. How would I resample my
Irregular2DSet. I think I am missing a dimension here. Can I enlarge my
FlatField from the Irregular2DSet?
I am attaching a TestCase, which includes an examples for my
Irregular2DSet. And I tried to resampled it into in Linear3DSet, but the
compiler give me the following message:
VolumeTest5.java:55: incompatible types
found : visad.Field
required: visad.FlatField
FlatField terrain_new
terrain.resample(set,Data.WEIGHTED_AVERAGE,Data.NO_ERRORS);
But the API of FlatField waits for an Set and Linear3DSet is a Set.
Sorry, I am confused.
Thanks for your help.
