[vtkusers] Print PolyData properties with VTK-Java Wrapping

[Gerrick Bivins]

Ignore my previous reply...read it too fast. Sorry.

You may need to call Update() on your MarchingCubes filter. I haven't used the "SetInput()/GetOutput()" version of the pipeline in a while
so I don't remember if calling MarchingCubes.GetOutput() necessarily updates the pipeline (ie executes the filter) before returning the output.

I believe you're looking for
System.out.println(polydata.Print())

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());
