Hi,

But I have one UnionSet for each time stamp. How would I animate all the
UnionSets?

This is the code that I have written ...
RealType[] time = {RealType.Time};
RealTupleType time_type = new RealTupleType(time);
RealTupleType xyz = new RealTupleType(x, y, z);
Gridded3DSet[] gsp = new Gridded3DSet[2];
FunctionType time_samples = new FunctionType(time_type,xyz);
DateTime base = new DateTime(1999, 122, 57060);
double start = base.getValue();
Set time_set = new Linear1DSet(time_type, start, start + 3000.0, ntimes1);
FieldImpl sequence = new FieldImpl(time_samples, time_set);
float[][] samples1 = new float[3][6];
samples1[0][0] = 291;
samples1[1][0] = 24;
samples1[2][0] = 255;
samples1[0][1] = 190;
samples1[1][1] = 92;
samples1[2][1] = 217;
samples1[0][2] = 261;
samples1[1][2] = 521;
samples1[2][2] = 232;
samples1[0][3] = 275;
samples1[1][3] = 943;
samples1[2][3] = 282;
samples1[0][4] = 276;
samples1[1][4] = 1051;
samples1[2][4] = 252;
samples1[0][5] = 273;
samples1[1][5] = 1460;
samples1[2][5] = 283;
gsp[0] = new Gridded3DSet(xyz, samples1,6);
FlatField anim = new FlatField(time_samples,gsp[0]); *****
sequence.setSample(1,anim);
The error I get is:
Exception in thread "main" visad.SetException: FieldImpl: set dimension 3
and type dimension 1 don't match for the line *****
FlatField anim = new FlatField(time_samples,gsp[0]);
I am wondering what is happening ... I might have made a very big mistake
somewhere but I really could not figure out putting the Gridded3DSet in
FlatField. Can anyone help?
Thanks,
Jay
