Track data from real-world action

Many techniques for data capture:

• Optical – take video and extract motion
• Magnetic/Radio – attach magnets, transponders and use sensors to get location

Use data to drive an articulated model

Motion capture is one of the primary animation techniques for computer games

• Gather lots of snippets of motion capture: e.g. dunk, dribble, pass
• Arrange the snippets so that they can be pieced together smoothly: match end points to start points
• At run time, figure out which pieces to play to have the character do the desired motion

Challenges:

• Data acquisition
• Associating motion to surface geometry
• Editing the data
