mocap dribbling a basketball?

by farstar » Thu Sep 22, 2011 5:58 pm

I am wanting to mocap a basketball player dribbling a ball. How do I go about setting this up to were I can capture the person and the ball as a prop?
Thank you in advance.

I have recorded such a motion with a ball, but processed with my own plugin - http://www.youtube.com/watch?v=Wwpo4B8Ijx0

Sergey,
That is exactly what I am needed to find out how to do. I would love it if you or someone else could tell me the steps in doing this properly.
1. What is the marker set up on a ball?
2. what do you save it out as?
3. how do you bring this data into 3ds max to work with biped rig?
Thanks again in advance on any help on this.

1. here is my marker setup - http://neill3d.com/wp-content/uploads/2 ... 00x300.jpg
2. I have saved it like point cloud from TrackingTools
3. I have processed data with special algorithm for fitting sphere into point cloud to reconstruct a ball center movement and get's a trajectory of a ball movement like on video above.

I see so you are using a point cloud. I am wondering if there is another way of doing this? Like how you would use prop with hard body?
