The parallel implementation of the volume rendering technique offers the potential of solving this computationally complex problem in reasonable times. This paper discusses a virtual memory strategy which is used to cope with the very large distributed data sets associated with the ray casting algorithm used for volume rendering. Various caching techniques are examined to reduce communication latency associated with remote data fetches within a transputer network. Multi-threading tasks are also investigated in order to minimise the effect of data fetch delay and improve overall system performance for large multiprocessor systems.
