Abstract: To meet the requirements of the large-scale virtual reality application in rendering speed and displaying resolution, a high-cost-effective distributed graphics rendering system, being based on a cluster of personal computers with multi-cores, was built. The system integrated the parallel in a node of the multi-core PC cluster and the parallel inter nodes. A flexible split-screen was achieved with scaling the frustum and moving the center of the projection. The efficiency of parallel rendering system was improved by multi-core parallel optimization of the rendering pipeline, loop iteration, functionlevel in the cluster node. The results of experiment show that the integration of multi-core platform and parallel rendering system improves effectively application performance through multi-threaded approach.
