[vtkusers] Possible to "convert" vtkPolyData to vtkImageData

[David Gobbi]

Feng,

The vtkPolyDataToImageStencil filter will do what you want.  Look at
Hybrid/Testing/Tcl/TestImageStencilWithPolydata.tcl.  For image data,
I wouldn't advise using a generic filter like vtkSelectEnclosedPoints
because it will be quite slow.
