Motion capture12/12/2023 ![]() ![]() 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. Mocap techniques allow the identification of bone or muscle abnormalities in the human body, facilitating the diagnosis of diseases or disabilities and their subsequent treatment.The following decades saw improvements on Harrison’s designs, with bodysuits more accurately recording movement. Motion capture is not only restricted to the field of entertainment, it also has very important uses in the field of health. This makes it possible for cartoons and video games to be as realistic as possible. Currently, the techniques are used to record the movement of actors and replicate it in 3D models generated digitally. ![]() ![]() ![]() Possibly the best known application of motion capture techniques is animation in the entertainment industry. Motion capture applicationsĪs has been seen so far, motion capture applications are many and varied. Released in 1989, it is considered the first video game to apply motion capture techniques, 70 years later and with very different purposes from those pursued by Max Fleischer. As a curiosity and as an example of this, we find the video game Prince of Persia. However, the development of this type of techniques was not immediate, but rather matured over time. Some sources place it in the year 1872, when the British photographer Eadweard Muybridge captured the movement of a horse using various cameras followed sequentially.Īs we will see in the next point, motion capture techniques have been used by a large number of different disciplines. When was motion capture invented?Ĭurrently, there is no unanimous consensus on the origin of motion capture. In this way, motion capture aims to produce 3D models that reflect the real movement of moving subjects. Motion capture is the process of capturing the movement of people, animals or objects, transferring it to a 2D or 3D model and animating it with the set of recorded movements. What is motion capture?įirst, let’s specify what we mean when we talk about mocap. In this article we analyze what motion capture is and how it works, reviewing its history and evolution. Motion capture, also known by “mocap”, “motion capture” or “motion tracking”, is responsible for a large number of advances in different fields such as medicine, industry of entertainment or, as is the case with the motion capture software developed by STT Systems, to improve the performance of professional athletes. ![]()
