I use the HardwareSelector and get some vtkSelectionNodes back. Now these nodes know their pixelcount on the screen, but nothing about their position. Is there any way besides going throught the mapper to accuratly get the 2D position of this selection?

I’ve been using the Hardware selector to get the point id and lookup its coordinates along with any field associated to it. I’m not sure that I understand your issue?
