Such systems are typically far more expensive, complicated, and time-consuming to use. Three-dimensional capture is accomplished using multi-camera rigs or laser marker system. This produces less sophisticated tracking, and is unable to fully capture three-dimensional motions such as head rotation. Two-dimensional capture can be achieved using a single camera and capture software. The capture may be in two dimensions, in which case the capture process is sometimes called " expression tracking", or in three dimensions. Because the motion of CG characters is derived from the movements of real people, it results in a more realistic and nuanced computer character animation than if the animation were created manually.Ī facial motion capture database describes the coordinates or relative positions of reference points on the actor's face. This database may then be used to produce computer graphics (CG), computer animation for movies, games, or real-time avatars. Process of electronically converting the movements of a person's face into a digital databaseįacial motion capture is the process of electronically converting the movements of a person's face into a digital database using cameras or laser scanners.
