[vtkusers] Rotate the camera

[tao sun]

Hi,


I am using vtkCamera::Elevation(double angle) to rotate the camera to flip
y axis. I noticed the possible angle range is -90~90. So is true for
vtkCamera::Pitch(double angle) if I tried to rotate the focalpoint instead.
However, I want the rotate a angle larger than 90, like 180. Does anyone
know how to solve this?


Thanks,
Sun Tao
