High Realistic Parallel Rendering System Based On GPU Cluster

With the fast development of computer and graphic technology, graphics rendering technologies are widely used in 3d simulation, virtual reality etc, protection of cultural relics. Software and hardware technology of graphics update every day, however, single PC computer still cannot afford high realistic real-time rendering of high complex scene. Three aspects about parallel rendering based on cluster are discussed in order to improve real-time performance as below:First, the framework of real-time ray tracing based on GPU cluster is presented and implemented. It efficiently explores the parallel power of GPU and improves the efficiencies of real-time processing of huge dada, which reduces the time of rendering.Second, in order to resolve load imbalance problem of common sort-first architecture, a dynamic load balance strategy using PBT is proposed, which enhances rendering efficiency.Real-time image compression method based on GPU is implemented in order to reduce the transmission time among GPU cluster, which improves the performance of the whole system.At last, a high realistic sense parallel rendering system based on GPU cluster is implemented for digital museum cultural heritage display.
