Hi,
We could also render the silhouette
(http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/Silhouette) which
would use the current camera position in the 3D view
This would go in the line of Rostislav's 3D node picking approach (Bug
1447 - picking of data tree nodes via vtk prop picker)
The selected objects could get their silhouette highlighted, like e.g.
in Blender.
best regards,
sebastian

Hi Rostislav,
I also wanted to enhance surface visualization by the edges so I can
see the opaque surface and the edges! I didn't yet have time for it. I
would absolutely vote for this feature / adaption!

Hi guys,
for me it was very useful to render the surface with edges. For that I
basically followed this simple example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/ColorActorEdges,
making changes to vtk surface mapper 3d (added two properties - edge
visibility & edge color and set the vtkProperty accordingly in the
mapper).
But it didn't work at first. It turned out that the problem is the use
of vtkOpenGLPolyDataMapper. But according to VTK docs,
vtkOpenGLPolyDataMapper is deprecated and replaced by
vtkPainterPolyDataMapper. When changing the vtkOpenGLPolyDataMapper to
vtkPainterPolyDataMapper in surface mapper, the edges were rendered
correctly. Is there any reason to hold on to the deprecated
vtkOpenGLPolyDataMapper? If not - I can easily give you the changes.
Rostislav.
