摘要 对三维地形场景并行渲染过程涉及的地形数据分页及分块和基于缓存的并行数据调度机制进行了归纳,总结了三维地形场景并行渲染相关算法及基于分布式和微机多线程的实现方式,并对目前并行渲染所存在的问题和发展趋势进行了分析。 The parallel rendering algorithms is the basement of 3D terrain parallel rendering. From the viewpoint of data scheduling and function implementation, parallel rendering can be categorized into data-parallel and function - parallel. In terms of the way multiple ren- dering pipelines are organized, parallel rendering can be categorized into Sort-first, Sort-mid-die and Sort-last. The platform for the parallel rendering systems can be high-performance computers, computer clusters or multi-core computers. Data paging, data blocking, and par- allel data scheduling mechanism based on data caching involved in 3D terrain are introduced. The parallel rendering algorithms involved in 3D terrain and the real systems based on dis- tributed architecture and multi-thread computer are introduced. The key problems faced by 3D terrain rendering are discussed. The future development of 3D terrain parallel renderingis discussed and some conclusions are proposed.
