• The process of recording live motion events, translating it into usable mathematical terms by tracking a number of key points in space over time and combining them to obtain a single 3D representation of the captured performance.
  • the captured subject is anything that exists in the real world and has motion.
  • these points should be piovet points or connections betweet rigid parts of the subject e.g joints of the actor
  • these points are known as potentiometers, sensors, markers
  • map the resulting data onto a 3D character

Different ways of capturing motion.

  • cameras that digitise different view of the performance
  • electromagnetic fields of ultra sound to track a group of sensors.
  • Potentiometers to determined the rotation of each link.
  • or technology with a combination of all to achieve real time tracking of unlimited number f key points
