[vtkusers] What happens when two actors are at the same depth?

[Stephane PLOIX]

Hi,

If your contour is made of lines, you try to
call GetProperty()->SetRepresentationToWireframe() on your contour actor
and tweak the vtkMapper::ResolveCoincidentTopology* parameters

Thanks for the answer. While this seems to be a clean solution, 
duplicating
the renderer means duplicating camera code, rendering etc. everywhere... 
So
I think I'll use a simpler solution instead, like a TubeFilter to add some
thickness to the contour or simply adding a little shift to the depth of 
the
contour (but that's not great either, because if I change the orientation 
of
the camera I'll have to change the shift too).

Thanks again.
