[vtkusers] Overlay Roads onto Terrain

[David.Pont at ForestResearch.co.nz]

I have succesfully created a triagle mesh using vtkDelaynay for my
terrain(actor) and I created my roads(actor) using vtkPolyLine.  At some
points the roads bisect the terrain. What I would like is the roads to lay
on the triangle "cells?" that form my terrain.

Hi Kelly,
  If your problem is coincident lines /  polygons, take a look at
vtkMapper->SetResolveCoincidentTopologyToShiftZBuffer et al.

Hello,

I am new to vtk and need some help getting started.

I have succesfully created a triagle mesh using vtkDelaynay for my
terrain(actor) and I created my roads(actor) using vtkPolyLine.  At some
points the roads bisect the terrain. What I would like is the roads to lay
on the triangle "cells?" that form my terrain.

Can anyone help?
