| 摘 要： | 光线跟踪算法所基于的Phong光照模型对于面片之间的辐射与色素渗透效应（即漫反射相互反射，diffuse inter-reflection）表现不足，本文在辐射度与Phong光照模型的理论基础上提出了一种高级光照模型，并对该模型建立了相应的简化模型，并给出了加速算法予以实现。

| Abstract: | This paper presents a kind of advanced lighting model based on Phong lighting and radiosity model to improve the traditional ray-tracing lighting model which lacks of the radiant-energy interactions (diffuse inter-reflection) between all faces in a scene. Based on this new advanced lighting model, more details can be transferred, and a simplified algorithm for ray-tracing based on the advanced model is presented and has been realized. |
