Hi All,

I am using vtkCamea Pitch() for getting Coronal and Lateral view of a bone model.  
But when I use Pitch value \> 87 I get below warning.

_**vtkRenderer.cxx:1164 WARN| vtkOpenGLRenderer (00000291DB33D650): Resetting view-up since view plane normal is parallel**_

Below is the code snippet I use

_femur\_fig.camera.Roll(0)_  
_femur\_fig.camera.Pitch(90)_  
_femur\_fig.camera.Yaw(0)_

Can somebody explain why vtkCamera behaves like this in case of Pitch()?  
In CloudCompare I am able to get desired coronal and lateral view using 90 degree Pitch/Rotation
