基于辐射度与Phong模型的高级光照模型及光线跟踪实现

Implementation of the High Level Lighting Model and Ray-tracing Based on Rediosity and Phong Model

光线跟踪算法所基于的的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,diffuseinterreflection)表现不足,该文在辐射度与Phong光照模型的理论基础上提出了高级光照模型,并对该模型提出相应的简化模型及加速算法予以实现。

This paper presents an 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 interreflection)between all faces in a scene.Based on this new advanced lighting model,more details can be transferred,a simplified algorithm for ray-tracing based on the advanced model is presented and has been realized.
