A SOFTWARE ARCHITECTURE FOR COLL ABORATIVE VIRTUAL PROTOTYPING

Prototype design and testing is an indispensable stage of any project development in many fields of activity, such as aeronautical, spatial, automotive industries or architecture. This paper describes the collaborative and distributed aspects of PROVIS, a system for prototyping virtual systems. The main goal of our work is to allow designers to replace physical mock-ups by virtual ones in order to test the integration and space requirements of the model components. While discussing PROVIS software architecture, the paper describes how to implement a complete computer system which allows users to collaboratively build and interact with virtual models.
