[vtkusers] Create an approximate cross-section of a RT ROI

[Lars Friedrich Lars]

Hi Xiaofeng,

just an idea:
- produce a surface from the axial contours by using vtkVoxelContoursToSurfaceFilter (which works quite well provided your source contours are evenly distributed)
- take vtkCutter(s) with plane implicit functions that define your new contouring orientation(s) and cut the volume to produce new contours from that directions

HTH,
lars
