    Abstract: Provided are three-dimensional still and animated object representations obtained from photos of real-life objects and their geometrical representations, allowing compact storage, fast rendering with high output image quality, suitable for animation purposes. The method includes transforming original data of a three-dimensional object into an intermediate representation; transforming data of the intermediate representation into a rendering representation in the form of a circumscribing cube, where a layered depth image is attributed to each face of the circumscribing cube, and rendering the obtained representation by determining visible faces of the circumscribing cube with account of the viewer's position, transforming the layered depth image for each of the visible faces into a texture, and visualizing the visible faces with texture.

    Abstract: A progressive and error resilient coding and decoding method of three-dimensional (3D) mesh data used in the fields of motion picture experts group-4 synthetic and natural hybrid coding (MPEG-4 SNHC), virtual reality modelling language (VRML) and the like. In transmitting 3D objects composed of 3D mesh data, it is very important to progressively and error-resiliently restore transmitted data as well as to effectively code the 3D mesh data. In the progressive restoration, in the event that a transmission data error is generated, partial restoration of the transmitted data is allowed. Thus, it is possible to minimize the amount of mesh data to be retransmitted and the standby time of a user. The progressive restoration method which is resistant to such transmission errors can be effectively applied in wireless communications or low transmission rate communications. In the progressive and error-resilient coding and decoding method, connectivity, geometry and photometry necessary for progressively coding 3D mesh data are constructed and then coded/decoded, thereby allowing incremental build-up and error resilience.
