[vtkusers] vtkTransform and vtkTransformPolyDataFilter

[ѧ־ Ñî]

Hi everyone, I has a problem with vtkTransform and 
vtkTransformPolyDataFilter. I use vtkTransform and 
vtkTransformPolyDataFilter to process a vtkPolyData, after that, use 
vtkCutter to cut through vtkPolyData with plan to get 2D contour of the 
object. The problem is here, I still can render the 2D contour to screen but 
when I use getBounds() function it seems return wrong result(tried to do 
intersection with other, but didn't recognize each other where there should 
be a intersection). I tried to use vtkTransform and 
vtkTransformPolyDataFilter again, but the same. Anyone know how to solve the 
problem? thank you very much
