[vtkusers] Problem with vtkPolyDataToImageStencil

[David Gobbi]

Thanks for the info.  There is one other thing you can try: you can force
vtkPolyDataToImageStencil to use double precision for its temporary
data.  At around line 183 in vtkPolyDataToImageStencil.cxx, you will see
  vtkPoints *newPoints = vtkPoints::New();
After this line, add the following to force the points to double-precision:
  newPoints->SetDataTypeToDouble();
Then recompile VTK and retry your code.
