光线跟踪是计算机图形学中一种高真实感绘制方法,传统的绘制算法忽略了光的偏振效应.而研究表明:在光线跟踪中加入光的偏振效应,能对绘制结果产生重要的影响.偏振光线跟踪是预测绘制技术的研究核心,它不仅可以提供高真实感的绘制效果,而且已被应用于偏振场景仿真和导航等领域.目前,偏振光线跟踪在国内尚未有相关工作.在预测绘制的框架下,根据偏振光线跟踪的流程,对偏振光线跟踪绘制技术的要点与关键问题进行了分析、总结与展望.

In computer graphics, ray-tracing is a high realistic rendering algorithm. Traditional rendering algorithms ignore polarization effect, while related studies show that polarization makes a substantial difference on rendering results. Polarization ray-tracing, at the core of predictive rendering, not only can provide high-realistic rendering image but also is applied in many other tasks such as navigation. Up to now, there is no related work around this topic in China. Under the framework of predictive rendering, this article provides an analysis and summary on key points and future works of polarization rendering following the procedure of polarization ray-tracing algorithm.
