Hi,

I try to move a SoPerspectiveCamera in OpenInventor wich always looks to 
a specific point (i.e. (0,0,0)).
I interpolate the position of the camera and reset the value of 
pointAt(...) in every step.
But the orientation of the camera is always the same and doesn't change. 
I also tried to interpolate the pointAt()-value, but the orientation 
keeps staying the same.

Do I have to set more than pointAt and the position of the camera to 
change its orientation?

Or how can I calculate the orientation out of the pointAt?

Thanks

You might do better in an Inventor newsgroup.
