Dynamic load-balanced rendering for a CAVE system

Published: 01 November 2006 Publication History

Abstract

Recently, PC clusters have been used to construct CAVE-like immersive projection displays. However, in order to improve the rendering performance of PC cluster-based CAVE systems, the number of node PCs should be increased in accordance with the number of screens that are included. In this research, a mechanism for dynamic load-balanced rendering in a PC cluster system incorporating an arbitrary number of nodes was developed. This system constructs the cluster system by using a chain connection-type compositor board, whereby load-balancing can be controlled dynamically in response to the movement of the virtual objects or of the user's viewpoint. This paper describes the implementation of this dynamic load-balanced rendering method and presents the results of an evaluation experiment.
