Thanks Victor, it looks clearly like an improvement. Only, the lightning seems to be specifically disabled here: d72d9b8 with a commit comment about wireframes. Can we disable it for wireframes maybe?

It's not a problem to enable lightning for shapes displayed as wireframe, I have just added
viewer.setRepresentationToWireframeForAllActors(); before launching the viewer, here are the results:

You have to turn it around to see the the difference ;) (I've tried it over here).

I don't understand what you want to point; the wireframe lines are shaded.
Is there anything wrong with this?

Run your test_shapes, press w turn model:

It happens because of the black background;

I added a new commit that changes the setRepresentationTo*ForAllActors () and the key s / w behavior.

Lighting for wireframe models is disabled
Lighting for surface models is enabled
