Re: Frame independent Camera Shake

Damping would be important to a realistic effect. Scale the
sine impulses by a  square or cubic function with a decay
of around a second. As Will says, the blur simulates high frequency
shake, so you don't really need to add higher harmonics onto
your sine waves if you have that - make it proportional to
the rms amplitude of the movement.
