Resource scheduling for coordinated display of structured presentations using a multi-disk architecture

Abstract

A structured presentation consists of a collection of objects (3-D representations) with spatial and temporal constraints along with rendering features such as shading and the audiences' viewpoint. A challenging task is to schedule the retrieval of objects from disk to display a presentation in real-time. The study introduces a taxonomy of such scheduling techniques and three techniques to support the display of structured presentations assuming a multi-disk architecture. These heuristics are evaluated using a simulation study to quantify their trade-offs. The results are compared with a theoretical minimum, demonstrating that one of the proposed techniques provides a performance almost identical to this minimum.
