I'll attach a simple example at the end in case you need a script example.</div><div><br></div><div>Also, just in case you didn't know, there is still the older QVTKRenderWindowInteractor which can be used to add a VTK render window to a PyQt app without building the SIP Python wrappers -- it's limited in a couple ways, but basically works fine for many applications.</div><div><br></div><div>Talk to you later,</div><div>-Eric</div><div><br></div><div>
