Plotting the geometry

[Gavin Tabor]

Hi there.

I'm writing code for a CFD postprocessor. I'm trying to write code
to display the mesh outline. I've got the mesh into a
vtkUnstructuredGrid
object, which is a good start, but I need to be able to display the
edges of this object. I can use a vtkGeometryFilter object to extract
the external mesh faces, but plotting these obscures the inside of the
mesh (obviously not a good idea). Is there any way of asking for the
edges of these mesh faces?

Thanks in advance for any suggestions.

Gavin
