vtkVoxelModeller and vtkStructuredPointsWriter

[Miguel Angel Martin Fernandez]

Hello vtk  users,

	I'm trying to write the output of the filter vtkVoxelModeller and
I only obtain 0's. I'm using VTK 2.4 (with VTK 2.0 it worked properly).

The tcl program is basically the next:

------------------------------
vtkSphereSource sphereModel

vtkVoxelModeller voxelModel
  voxelModel SetInput [sphereModel GetOutput]
  voxelModel SetSampleDimensions 21 21 21

vtkStructuredPointsWriter writer
  writer SetFileName prueba.vtk
  writer SetInput [voxelModel GetOutput]
  writer Write
------------------------------

The file obtained is the next:

# vtk DataFile Version 2.0
vtk output
ASCII
DATASET STRUCTURED_POINTS
DIMENSIONS 21 21 21
SPACING 0.14924 0.14683 0.15
ORIGIN -1.4924 -1.4683 -1.5
POINT_DATA 9261
SCALARS scalars int 1
LOOKUP_TABLE default
0 0 0 0 0 0 
0 0 0 0 0 0 
... (skip)
0 0 0 0 0 0

	Do you know what is wrong?

	Thanx in advance.

	Miguel.
