[vtkusers] Trouble creating isosurface from unstructuredGrid of Tetras - Fixed!!!

[scotsman60]

So,

The problem is that we need to call the Update method on the
vtkContourFiler() before passing it to the vtkPolyDataMapper.......

# Generate an isosurface
contour = vtk.vtkContourFilter()
#contour = vtk.vtkMarchingCubes()
contour.SetInputData( tetMesh )
contour.ComputeNormalsOn()
contour.SetValue( 0, 0.00 )
*contour.Update()*

Everything seems to be OK now.......
