Towards Dynamics Animation on Object-Oriented Animation Database System "MOVE"

The authors present why and how to develop three dimensional animat8ion database system MOVE. Three dimensional animat,ion system is an import,ant application of mutilmedia &abase syst,em, because many animators and eugineers want the management8 facility of animation da.tit. The authors designed MOVE in object-oriemed way. They implement.ed three dimensional animation database schema on a conventional Object-Oriented Dat,abase Management System (OODBMS). The schema contains some basic classes for three dimeusional computer graphics such as vector operations, three dimensional object, polygonmeshed curved surface, and local illumination model. They also implement,ed basic algorithm like t,he Z-buffer algorit.hm and scan-line algorit,hm. Using MOVE, users can combine basic comput8er graphics objects and can build a scene. They can also ext.& t,hese classes wit,hout knowing the dc%ils of MOVE. .\nd imerface bet.ween simulation program and computer graphics rominea is discussed here from the point of view of kinemabic constraint and dynamics simulation.
