摘要
本文主要研究电波传播模拟中重要的方法射线追踪法的算法改进问题。讨论在射线发射阶段的优化算法,通过设计一种新的数据结构来达到动态追踪的目的。最终在保证精度的前提下减少追踪射线的条数,减少追踪时间,实现算法优化。
This paper mainly researches an improvement on shooting and bouncing ray tracing algorithm, which as an important method of wave spread simulation. This paper focus on optimization of the ray’s launch phase, and designs a new data structure in order to make the ray tracing dynamically. Finally it reaches the goal that reducing the number of the rays and the time of ray tracing within the error range allowed.
