[vtkusers] vtkRenderer.AddActor

[David Cole]

VTK is not easily usable from multiple threads. So, in general, you should restrict access to VTK objects to a single thread in your app, or use mutexes to guarantee that only one thread at a time has access to VTK objects. And, if you have to pick a thread to restrict the access to, use the same one that’s doing all the GUI stuff -- VTK rendering has to run in the GUI thread anyhow.
