We describe a predictive memory management system that allows the visualization of 2D graphic objects in real time. This system is based on a virtual memory model. We show how the page loading system predicts and fetch data before it is accessed by the application and how the page replacement system decides which data should be removed from memory. We demonstrate the effectiveness of the system for real-time visualization of panoramas.
