Abstract
This paper reports the Visualization Subsystem for the Sensable Simulation System(Scube) which the authors have been developing. Scube is a 64-nodes PC-based cluster system in which a commodity GPU as the visualization accelerator is configured with each node. There is no dedicated special purpose network for the visualization, however, the high-cost performance inter-connection network is originally designed for Scube. All the hardware components for this network is essentially the small-scale and commodity hardware designed for Giga-bit Ethernet. The authors have also designed the binary-tree based parallel image composition algorithm which utilizes the degree of overlapping between sub-images, in order to reduce the amount of unnecessary communication and computation. The details of the image composition algorithm and the network configuration are described in this paper.
