Title: TeCo3D: a 3D telecooperation based on VRML and Java
Published: Proc. of Multimedia Computing and Networking (MMCN) '99, pp. 240 - 251, San Jose, CA, USA, January 1999

Abstract: In this paper we present a method for sharing collaboration-unaware VRML content, e.g. 3D models which were notspecifically developed for use in a distributed environment. This functionality is an essential requirement for the inclusion ofarbitrary VRML content, as generated by standard CAD or animation software, into teleconferencing sessions. We havedeveloped a 3D TeleCooperation (TeCo3D) prototype to demonstrate the feasibility of our approach. The basic servicesprovided by the prototype are the distribution of cooperation unaware VRML content, the sharing of user interactions, and thejoint viewing of the content. In order to achieve maximum portability, the prototype was developed completely in Java. Thispaper presents general aspects of sharing VRML content as well as the concepts, the architecture and the services of theTeCo3D prototype. Our approach relies on existing VRML browsers as the VRML presentation and execution engines whilereliable multicast is used as the means of communication to provide for scalability.
