The most common sensors used in IMUs are gyroscopes, magnetometers, and accelerometers.Wang, X., Zhu, X., Zhao, J., Xu, H.: The research of real time motion capture technology in film and television animation.

It records movement through IMUs (inertial measurement units), which contain sensors to measure rotational rates. Inertial – This technique doesn’t necessarily need cameras to operate.

Whilst more convenient in some ways, it’s generally considered less accurate than its optical or mechanical-tracking alternatives. It relies on depth-sensitive cameras and specialised software in order to track and record moving people and objects. Marker-less – This technique doesn’t require markers of any sort.The markers therefore require a power source. Optical (active) – This technique is exactly the same, but the markers emit light rather than reflect them.Once reflected, the light is used to calculate the position of the markers within a three-dimensional space, and recorded. Optical (passive) – With this technique, retroreflective markers are attached to bodies or objects, and reflect light generated from near the camera lens.Nowadays, there are four main motion capture techniques: The character and technology were created on the fly by Weta Digital’s Bay Raitt. The combination of the character’s voice and intricate facial expressions performed by Andy Serkis resulted in an unforgettable motion-capture performance. Among CG-created characters, The Lord of the Rings’ Gollum is recognised as one of the most impressive Hollywood has ever produced. The film was a flop, but its use of mocap was picked up and expanded on by Peter Jackson in his making of The Lord of the Rings Trilogy in the early 2000s.įor the first time ever, actors wearing their bodysuits (complete with retroreflective ping-pong balls) could perform alongside their non-animated colleagues in the same scene.

While mocap had been used sparingly in the 1980s and 1990s with films like American Pop (1981) and Cool World (1992), the first film to be used entirely using the technology was Sinbad: Beyond the Veil of Mists (2000). They were also helped by the development of large tracking cameras as useful as they were, however, each was about the size of a fridge. The following decades saw improvements on Harrison’s designs, with bodysuits more accurately recording movement.
