[vtk-developers] Anti-aliasing / multi sampling in QVTKWidget2 ?

[Kilgus, Thomas]

Dear List,

we recently switched from QVTKWidget to QVTKWidget2 and now by default anti-aliasing is disabled.

We managed to track the issue down with this VTK example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Qt/RenderWindowUISingleInheritance

Just render the sphere in wireframe mode. If you run the example with a QVTKWidget, lines are smooth and with QVTKWidget2 they are stepped. SetMultiSamples(8) should do the job, but this does not have any effect (and is the default value).

Any ideas on this?

Regards,
Thomas
