| 摘 要： |
| 在个人通信以及移动通信环境中，光线跟踪是预测无线电波传播特性的常用技术，光线跟踪算法是真实感图形生成中最好的方法并且也能用于光散射特性的计算。把光线抽象为射线，基于射线方程和三锥体表面方程计算射线与三锥体侧面的交点，如果光线与三锥体相交，离光线发射点最近的点，就是射线与三锥体的交点，得到交点，可以计算折射光线和反射光线。设计三锥体的光线跟踪算法，给出不同参数下的三锥体的光线跟踪结果，从结果可以得到：仿真程序能够准确地模拟出光线在三锥体外面和内部的传播过程，设计的三锥体光线跟踪算法是正确的。 |

| Abstract: |
| Ray tracing is a common technique for predicting the propagation characteristics of radio waves in personal and mobile communication environments. Ray tracing algorithm is the best method of realistic graphics generation and it can be also used in the calculation of light scattering characteristics. See light as rays, the point of intersection of between rays and the lateral surface and bottom of a triconic are calculated based on the ray equation and the surface equation of the triconic. If the ray intersects the triconic, the point nearest to the point of emission of the ray is the point at which the ray intersects the triconic, and the intersection point is obtained, than refraction ray and reflection ray can be calculated. The ray tracing algorithm of triconic is designed. The ray tracing results of triconic about different parameters are given. From the results, it can be concluded that the simulation program can accurately simulate the propagation process of light outside and inside a triconic, and the ray tracing algorithm designed of triconic is correct. |
