摘要:
为满足大规模虚拟现实应用在渲染速度和显示分辨率等方面的要求,提出基于场景图技术的并行渲染,使用PC集群构建了高性价比的分布式图形系统.利用场景图在视景体内的快速裁剪技术,有效提高图元的归属判断速度.研究了OpenFlight格式与sort-first任务粒度划分的关系,基于场景图的层次结构来划分图元组.在保留模式下实现了一个基于场景图的sort-first原型系统,并用软件方式实现了多显示通道的无缝拼接.该系统同时考虑了CPU的功能并行和GPU的数据并行,提升了大规模场景漫游时的运行速度.
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．
