[vtkusers] How to use SetResolveCoincidentTopologyToPolygonOffset

[Jothy]

Hi all,

I am trying to overlay a contour cut from a mesh using vtkCutter. But the
contour always lies behind the imageactor. I have read somewhere that to
resolve this issue we need to set

*vtkMapper::SetResolveCoincidentTopologyToPolygonOffset().


I am using vtkRenderer with vtkRenderWindow and not vtkImageViewer2
for the visualization. To which mapper I need to set
SetResolveCoincidentTopologyToPolygonOffset? Then, is it necessary to
set
SetResolveCoincidentTopologyPolygonOffsetParameters(10,10);**


Thanks

Jothy**
