Resetting view-up since view plane normal is parallel
vtkOpenGLRenderer (000002D0898B0170): **Resetting view-up since view plane normal is parallel**
I'm using VTK 8.0 with Qt. While I try to implement camera pitch operation for the values more than +88 and -88, the above mentioned warning appears and resets the object. Can someone help me out to find solution for this problem?
