PDJ Weekly Livestream # 41 - Motion Capture Update  @harrisonlow
Uploaded December 2024 | Updated September 2026, 1 hour ago
This last week has been a little slower than usual; I've had a few other things going on and have been fiddling with the motion capture software (QTM) to get a better feel for how it works.

That said, we've now got some decent ball tracking that's capable of handling multiple balls at once and (minor) occlusions, with fairly accurate predictions of where the ball(s) will land!

This is a big step towards Jugglebot being able to 'partner juggle' with me. Very keen! 😁
