Hi,  
total VTK newbie here, I am trying to run one of the iOS examples but get stuck here:

#include “vtk/vtkRenderingOpenGL2ObjectFactory.h” is not found, which seems to only be used by iOS examples, and only in this line of code:  
vtkObjectFactory::RegisterFactory(vtkRenderingOpenGL2ObjectFactory::New());  
I cant find the file in any VTK versions, very strange indeed. There is only one documentation page from version 7.0.0, but also there this file does not exists? Is this autogenerated somehow?

Did someone manage to run an iOS example with VTK8 and could point me to some source code?

best,  
Victor

I have the same problem. Have you solved it?
