High-performance computing for surface modelling and analysis

Real-time response and updating, and concurrent use of complex models are problems which require a high computational effort and might thus benefit from the use of parallel processing. These problems typically occur in surface analysis, a key tool for shape understanding and processing. We survey different applications,of parallel processing at different stages of the shape-understanding process. The emphasis is on parallel program portability and reuse of sequential software. Results are provided for different architectures like workstation networks and massively parallel machines (Cray T3D).
