Here's a much faster way, if you only want to show points:
RealType index = new RealType("index");
FunctionType fxyz = new FunctionType(index, xyz);
Integer1DSet set = new Integer1DSet(testsamples[0].length);
FlatField field = new FlatField(fxyz, set);
field.setSamples(testsamples);
points_ref.setData(field);
. . .
Since you are only showing points, the considerable time
to compute the Delaunay triangulation topology in the
Irregular3DSet constructor is not necessary.
Good luck,
Bill
