具有坐标旋转变换的时空相对效应光线跟踪系统

由于基于牛顿经典理论的传统光线跟踪法无法实现物体高速运动时的时空相对效应可视化，本文提出一种改进的光线跟踪系统。通过定义一组参数，使得不同惯性参照系中的坐标系的轴经旋转变换后相互对齐平行．通过建立四维数据结构及加入媒介信息堆栈，可以准确计算光线在媒介中的传输速度及延迟，实现时空系统中光的透射及折射现象的可视化。

RAY TRACING SYSTEM OF SPACETIME RELATIVISTIC EFFECT WITH COORDINATE ROTATION

As the traditional ray tracing methods based on Newton's classical theories cannot realize the visualization of spacetime relativistic effect while objects moving at a high speed, an improved spacetime ray tracing system is proposed in this paper. After rotating operations, the axes of coordinates in different inertial reference frames are aligned with each other through defining a set of parameters. With the establishment of a new group of 4D scene data structures and a medium information stack, the light transmission speed and transport delay in medium can be calculated accurately, and the visualization of the transmission and reflection phenomena in spacetime system can be realized.
