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 conv...

We propose an architecture for virtual environments that is aimed at the construction of a global, continuous, shared, and persistent information space. Such a system must support three-dimensional interaction of a large number of users and allow integration of user-developed applications. Our system is based on a client-server architecture: The server is responsible for management and maintena...

Ability to stack separate chips in a single package enables three-dimensional integrated circuits (3D ICs). Heterogeneous 3D ICs provide even better opportunities to reduce the power and increase the performance per unit area. An important issue in designing a heterogeneous 3D IC is reliability. To achieve this, one needs to select the data mapping and processor layout carefully. In this paper,...

The ability to model 3D objects from monocular video allows for a number of very useful applications, for instance: 3D face recognition, fast prototyping and entertainment. At present there are a number of methods available for 3D modelling from this and similar data. However many of them are either not robust when presented with real world data, or tend to bias their results to a prior model. ...

The classical Z-buffer algorithm samples a scene at regularly spaced points on an image plane. We present an extension of this algorithm called the irregular Z-buffer that permits sampling of the scene at arbitrary points on the image plane. The sample points are stored in a two-dimensional spatial data structure which is queried during rasterization. The irregular Z-buffer can be applied to sh...
