This paper provides a framework for information assurance within collaborative design, based on a technique we call role-based viewing. Such rolebased viewing is achieved through integration of multi-resolution geometry and security models. 3D models are geometrically partitioned, and the partitioning is used to create multi-resolution mesh hierarchies. Extracting an appropriately simplified mo...
