ABSTRACT
Animations of 3D models are an interesting type of media that are increasingly used in multimedia presentation such as streaming of 3D worlds in advertisements as well as in education material. The most popular way to generate animations of 3D models is motion capture through the use of motioncapture devices and 3D digitizers. In this method, 3D models are first digitized using 3D scanners. Then, applying automatic process and user-computer interactions, the moving structures of the models (e.g., skeletons and joints) and their motion parameters (e.g., translation, rotation, sliding, and deformation) are defined. Third, motion sequences are captured using the optical or magnetic motion capture devices. Finally, animations, the motion sequences and 3D models, are stored in animation databases for further use.
