In the late 90's, the emergence of high-performance 3D commodity graphics cards paved the way to the use of PC clusters for high-performance Virtual Reality (VR) applications. Today PC clusters are broadly used to drive multi-projector immersive environments, among other high-performance VR tasks such as tracking and sound synthesis. This survey presents the different approaches that have been developed to use PC clusters for VR applications. We review taxonomies and the most common software and hardware tools that enable us to take advantage of clusters. We also discuss some new trends for the near future.
