ABSTRACT

3D data is being processed in a number of application domains such as, engineering design, manufacture, architecture, bio-informatics, medicine, entertainment, commerce, science, defense, heritage, etc. The volume of 3D data that is being circulated on the Internet is increasing very rapidly. Adding to this trend further are new developments like availability of inexpensive 3D scanners and 3D graphics accelerators, sophisticated 3D gaming devices, and increasing use of 3D imaging in distributed collaborative work in virtually all domains like engineering, scientific research, education, entertainment, commerce, etc. Clearly like text, images, audio and video, 3D data is emerging as yet another media type that has to be processed and visualized. Transmission issues concerning 3D data are instrumental for the distributed use of 3D information. In this paper we identify the major requirements for remote interactive access to locationally distributed 3D data, and then briefly describe two new compressed 3D data transmission techniques, developed by the authors. The first technique is for triangulated models representing individual, complex 3D sculptured objects, while the second is for large architectural and engineering class of models, typically large assemblies of a few types of components. Both techniques have the properties of high compaction ratios, fast decompression and low decompression latency, making them very well suited for rapid distribution and retrieval of 3D data on the Internet.
