Hello all,<br>
<br>
I have a structured grid, and I want to plot a surface contour with<br>
overlaid grid lines. To get the surface, I have a pipeline like this:<br>
surface grid -> vtkGeometryFilter -> vtkPolyDataMapper -> vtkActor<br>
<br>
To get the grid lines, I take the output of the geometry filter and<br>
extract edges:<br>
vtkGeometryFilter -> vtkExtractEdges-> vtkPolyDataMapper -> vtkActor<br>
<br>
However, the rendering of the lines clips the surface, leading to poor<br>
output as in the attached image. How can I lift the lines off the<br>
surface to get correct rendering?<br>
<br>
Thanks,<br>
