| 摘 要： | 提出了一种全局光照计算方法,结合了两个知名的技术,光子映射和辐照度缓存.光子映射具有视点无关的优势,辐照度缓存可以快速计算间接光照,但后者是视点相关的,为了使光照缓存记录覆盖整个场景,辐照度缓存算法需要手动设置很多相机.利用这两种技术的各自优势,通过光子图来计算改进后的视点无关的辐照度缓存算法,实现了快速而准确的全局光...

| Abstract: | This paper presents a global illumination method combining two well-known techniques: photon mapping and irradiance caching.The photon mapping method has the advantage of being view independent,irradiance caching can quickly calculate indirect light,but the latter is view-dependent.To compute records covering the entire scene,the irradiance caching method has to be run for many cameras.Our method exploits the advantages of these two methods to achieve fast and accurate calculation of global illumination by ... |
