View Full Version : Averaging keyframes?

Is there a script out there that will take a range of keyframes on a selected channel, say y rotation, and average their values over a user defined number of frames? Is this something someone could quickly write, or is it a big deal. I'm looking for something like the 'Average' tool in Combustions math operations dialogue.

Thanks

I believe something like this would work. This is for Y rotation:


controllerKeys = $.rotation.controller[2].keys
keyValues = #()
avg = 0.0
for k in controllerKeys do (
append keyValues k.value
)
for v in keyValues do (
avg += v
)
avg = (avg / (keyValues.count as float))

Is this what you are looking for? Not sure how I'd apply this to a specific range.

fn sakAvgTest fMin fMax = (
controllerKeys = $.rotation.controller[2].keys
keyValues = #()
avg = 0.0
for k in controllerKeys do (
if (k.time > fMin AND k.time < fMax) then (
append keyValues k.value
)
)
for v in keyValues do (
avg += v
)
avg = (avg / (keyValues.count as float))
)

Okay, I think this works. It's averaging key frame values though

Thats exactly what I needed! Thank you for taking to time to help me. I have motion capture data that was very noisy, and I needed a way of smoothing it out.
