[vtkusers] Print PolyData properties with VTK-Java Wrapping

[Ricardo A Corredor J]

Hi,

I'm just trying to use vtk with the Java wrapping and I have a question
after making a little test. Actually, I have a polydata as the output of a
filter (vtkMarchingCubes). I can display the actor in the scene, but if I
print the polydata itself it seems that it is "empty".

Is it something normal of polydata's structure?

I show you the little part of code and the message printed:

vtkMarchingCubes marchingCubes = new vtkMarchingCubes();
marchingCubes.SetValue(0, 128);
marchingCubes.SetInputConnection(binaryImageReader.GetOutputPort());
marchingCubes.ComputeScalarsOff();

// PRINTING POLYDATA
vtkPolyData polyData = marchingCubes.GetOutput();
System.out.println(polyData);
System.out.println();

vtkPolyDataMapper mapper = new vtkPolyDataMapper();
mapper.SetInputConnection(marchingCubes.GetOutputPort());
