- Abstract:
-
Scene graph—based parallel rendering is proposed to build cost—effective distributed graphics sys—tem based on PC cluster in order to meet the need of large scale virtual reality applications.The procedure ofprimitives belongingness determining is speeded up using the fast view frustum culling technology of scenegraph.The relationship between OpenFlight scene data format and the task granularity of sort·first is also re—searched and primitive groups are built based on the hierarchy of scene graph.We have realized a scene graphbased sort—first prototype system which achieved seamless tile using the software way in retained mode.Boththe function parallel of CPUs and the data parallel of GPUs is considered in this system,and it could improveframe rate while We ran large scale virtual scenes.
