摘要: 针对大规模复杂几何表面的物理场三维可视探查,在三维电磁仿真模拟应用中具有重要应用价值。提出一种适用于大规模并行处理的三维数据探查技术:它通过引入探测体和被探测数据集的双数据源概念和基于合约的数据预筛选策略,在可视化底层实现了针对大规模三维数据探查的高效支撑;针对任意复杂几何表面的精确三维探查,则是基于空间包围盒的探测体切割算法和基于探测体几何表面的数据探测算法。研究成果已被成功应用于机身蒙皮电场的特征分布分析和导引头高价值目标电磁损伤精确评估等复杂电磁环境重大实际应用之中。

Abstract: Three-dimensional physical field data exploration visualization based on large scale complex geometric surface is of great value in three-dimensional electromagnetic simulation applications. Research was proposed which was suitable for massively parallel processing technology of three-dimensional data exploration. The concept of dual-data-source and data filtering policies was introduced based on contracts. Clipping algorithms based on spatial bounding box and data probing algorithm can support accurate three-dimensional data profiling for complex surface geometry. Research results have been applied to significant practical applications, such as the fuselage characteristics of electric field distribution analysis and high value targets within the seeker's accurate assessment of electromagnetic injury complicated electromagnetic environment, and get better results.
