[vtkusers] Cutter overlay on image

[David.Pont at ForestResearch.co.nz]

I am currently working with mixed polydata and images. For the images I
have:
     vtkTIFFReader->vtkTexture
     vtkPlaneSource( sized with image dimensions )
->vtkTransformPolyDataFilter->vtkPolyDataMapper->vtkActor( SetTexture with
texture created from image )

For the polydaya it is the usual, similar to the latter part above:

     MyPolyData->vtkTransformPolyDataFilter->vtkPolyDataMapper->vtkActor

One, or both transforms may not be required, depending if you inputs (image
and polydata) are in the same coordinate system.

  regards
     Dave Pont

I am getting the cross-section of some poly data with a vtkCutter and
would like to overlay this onto the output of a vtkImageReslice in the
same window. What is the best way to do this? Thanks.
