Re: [Algorithms] Converting translation data to rotation data and Reducing noise

[Emanuele S. <in...@fo...>]

Oh, and about filtering, usually you keep the mocap data as raw as it =
gets from the acquisition software, and then smooth the anim curves out =
into your animation software.

Again, usually the mocap software already removes spikes in a given =
range (value/time), but that's based on the sampling frequency.
Vicon8 optical samples at 120Hz, so, time values for interpolation are =
very narrow.

That's why you usually end up cleaning anim keyframe curves into your =
anim software...rebuilding curves by interpolation once you have your =
"production" frame rate in place. (....I don't know of anyone doing =
anims at 120 Hz...maybe for some "slow-time" Matrix effect?! ^_^)
