【摘要】 提出一种基于室内环境的二维模型射线跟踪的实现方法。该模型可以从AutoCAD中提取出描述室内障碍物的几何外形和位置等参数并将其存入适合射线跟踪的数据结构,然后利用射线跟踪算法模拟出射线的传播路径。计算机实例表明,该模型能够有效的模拟出从场点到射线源点反向追踪路径。更多还原

【Abstract】 An implementation of the indoor two-dimensional ray-tracing model is presented.This model can extract the parameters including the geometrical shape and location of indoor barriers from the AutoCAD and save them in the data structure that adapt to the ray-tracing,then accord the algorithm of ray-tracing to simulate the route of radiation.Simulation results show that the model simulate effectively reverse route of ray-tracing from the terminal to source.更多还原
