[vtkusers] how can i clip the vtkImageData using the vtkPolyData? thank you in advance~

Hi Ye,

You can use vtkPolyDataToImageStencil in combination with vtkImageStencil.

Something like

polydataToImageStencil->SetInput( polydata );
imageStencil->SetStencil( polydataToImageStencil->GetOutput());
imageStencil->SetInput( imagedata );

The output of imageStencil is your clipped polydata. I've seen some issues
with the class in the past though, leaking through tight edges of the
polydata etc, but it might work for you.
