摘要

我们提出了一个积分方程，它推广了各种已知的绘制算法。在讨论蒙特卡罗解的过程中，我们还提出了一种新的方差缩减形式，称为分层抽样，并给出了一些详细说明，表明它可能是一种适用于各种蒙特卡罗程序的有效新技术。由此产生的绘制算法扩展了可以有效模拟的光学现象的范围。

The rendering equation

We present an integral equation which generalizes a variety of known rendering algorithms. In the course of discussing a monte carlo solution we also present a new form of variance reduction, called Hierarchical sampling and give a number of elaborations shows that it may be an efficient new technique for a wide variety of monte carlo procedures. The resulting rendering algorithm extends the range of optical phenomena which can be effectively simulated.
