[osg-users] Smoothing camera movements from HMD's input.

I'm integrating a head mounted display (HMD) in my OSG application, the
HMD's APIs give me Euler's angles (yaw, pitch and roll) and I use them to
adjust my scene's camera view using an update callback.

But I noticed that, changing camera view from frame to frame, results in
jerky movements, even when I try to rotate my head very slowly.

In order to solve this problem, I was thinking about creating an animation
path (on the fly) from a previously stored orientation to current head
orientation. Is this the correct way to proceed? Or there is some other
technique to smooth the resulting camera movements?

Thank you. Best regards.
