Good experiment.

Idea with nunchucks attached to different parts of body – easy way to get EulerXYZ for bones, but not for CS.

Hi there
I posted some more details on my blog.

@john park : I wanted to emulate a joystick (or mouse) bu using processing as an HID device, but it seemed to be impossible. I'm not really into C code or assembly, so unless I can have AVRUSB running on the arduino, I'll stick with MIDI controls and all the problems that comes with. HID would be the best option, of course.

@jon : as by s said, there's a record button that I did not press for this video. I just used the test functionnality, but if you really really really want, I can make another video with the record feature ^^

@by s : in fact, it's useless ^^ but it was an early experiment. I wanted to see if I could get datas from the arduino to a 3D software to test the inverse kinematics equations I'm trying to implement for a robotic "arm" with 5DOF. Now that I did it (still needs a lot of improvement), I know that it's feasible and I have a lot of other ideas for it ^^

@bryan riabs : that's exactly the kind of thing I'm thinking of ^^

Thanks for posting this here, guys :)

my idea would be make a 3d human and attach a bunch of nunchucks to different parts of my body to move the human. No need to capture with the all little ping pong balls.

well, it wouldn't be hard to record the movements from there
i'm not sure, but i think there's a record button for this
if not, maxscripting is still a valid option, and very easy as we already have it moving
just a matter of laying down the keyframes
but all in all it is a pretty useless gimmick
call me when you have it in realtime toribash

or equivalent

Wow the description here makes it sound like it’s capturing the movement, but if you read the vimeo video description (all of one sentence) he’s just controlling what’s in the viewport with the wiimote. Still cool, but not motion capture at all.

So if you’re looking for a cheap way to do motion capture in 3ds max, look elsewhere. Or learn to rotoscope :D

That’s pretty darned cool. IIRC 3d studio max ships with mouse “mocap” drivers, so I wonder if you could do an additional set of controls using the wiimote with some mouse pointer software directly.
