Thank you Jochen, Update() does not do the trick, there is still nothing displayed in the multiwidget..
It seems to be a vtk issue rather than a problem with the Surface. I copied the implementation of the iso surface functionality (which also uses a Surface, but aquired from a filter via GetOutput() ) for testing and it works without any problems. Anyone have other suggestions?
