Re: [Algorithms] Frame independent Camera Shake

[Jason H. <jh...@st...>]

Yes.  You don't want the camera position to wander away, so the random 
amount is an offset from where the camera 'actually' is, before applying 
any shake.  Every frame, you just pick a new spot to put the camera.  
The intensity is controlled by the scale factor.  You might want to make 
sure the shake vector is a randomized unit vector within the plane 
parallel to the near plane (ie. XY in camera local space), so you can 
get more reliable results.  Or perhaps non-unit will appeal to you.  
That's more a matter of taste than science at this point.
