提出了一种基于光子映射的复杂室内场景核外全局光照计算方法。我们的方法利用细胞和门户网站表示的环境，以保持内存的一致性和存储射线或光子。我们已经成功地将我们的方法应用于各种建筑物，这些建筑物由多达10亿个三角形组成。如结果所示，我们的方法只需要几百兆字节的内存就可以在大型建筑物中追踪超过16亿个光子。
This paper describes a new scheme for computing out-of-core global illumination in complex indoor scenes using a photon-mapping approach. Our method makes use of a cells-and-portals representation of the environment for preserving memory coherence and storing rays or photons. We have successfully applied our method to various buildings, composed of up to one billion triangles. As shown in the results, our method requires only a few hundred megabytes of memory for tracing more than 1.6 billion photons in large buildings.
