[vtkusers] Showing orthogonal slices

[Hendrik Belitz]

For an medical application, I want to show three orthogonal slices of a volume 
dataset. 
Extracting these slices via vtkImageDataGeometryFilter provides good results, 
but produces large meshes which slow down the application significantly 
(there's also a lot of additional geometry shown in the application). 
A much better solution would be to extract the image slices and show them as a 
texture on a simple plane. My problem is to find a suitable vtk class to 
extract an 2D vtkImageData slice from a 3D vtkImageData dataset. Does anyone 
of you has some advice on this?

Regards
Hendrik
