提出了一种新的基于后向光线追迹后向光束追迹的两遍法。其优点包括渲染复杂的，迄今无法实现的，镜面反射到漫反射现象的能力，它很容易插入到标准渲染器。该算法适用于光与水的相互作用方面。在此上下文中，各种第一代效果（包括阴影和光散射）都被渲染和动画化。从经典光学焦散线的治疗采取的结果包括在内，因为它们提供了宝贵的见解镜面漫反射转移的精确性质。
A new two pass approach is presented based on a variation of backward ray tracing backward beam tracing. Advantages include its capability of rendering complex, hitherto unattainable, specular to diffuse phenomenon and its easy insertion into standard renderers. The algorithm is applied to aspects of the interaction of light with water. Within this context a variety of first generation effects, including shadowing and light scattering, are both rendered and animated. Results taken from the treatment of caustics within classical optics are included as they provide valuable insights into the precise nature of specular to diffuse transfer.
