摘要
在分析LOD内在并行性的基础上,利用通用的并行编程环境OpenMP对其进行线程化,提出了一种基于四叉树网格划分的并行简化算法,并在四核计算机上应用Intel parallel amplifier分析器按函数查看性能变化,对比优化前后的数据,结果表明并行化后的加速比和计算效率有了显著提高。
Using OpenMP which is general-purpose parallel programming environment to realize LOD threaded based on analyzing inherent parallelism of LOD.A parallel simplification algorithms of quad-tree mesh divided is proposed.According the function of the view change of properties and using Intel parallel amplifier analysis device in the four-core computer the former data and hinder data are compared.The experimental result shows that the parallel speedup and efficiency are improved significantly.
