Re: [Algorithms] Frame independent Camera Shake

[Jon W. <jw...@gm...>]

In general, shake is a sum of almost-instantaneous impulses off-center, plus
the attempts of the camera person to center the camera. Thus, you can
implement camera shake as a sequence of random impulses (Brownian motion
style), and a first-order error correction dampened spring. The rate and
magnitude of impulses are two main tweakables, plus how much the shake
affects camera orientation vs position (turns out, orientation is much
wilder than position :-)
I'd start with 3 degrees of orientation affect at 5 Hz, and then tweak from
there (or set it at that and let the artists make it right :-)

Sincerely,

jw
