全局光照(Global Illumination,简称 GI), 作为图形学中比较酷的概念之一,是指既考虑场景中来自光源的直接光照,又考虑经过场景中其他物体反射后的间接光照的一种渲染技术。 大家常听到的光线追踪,路径追踪等同样很酷的概念,都是全局光照中人气较高的算法流派。 而这篇文章将围绕全局光照技术,介绍的要点有: 全局光照的...
这一章从基本的物理现象开始,覆盖各种渲染材料的模型,最后给出了混合材料并过滤它们以避免走样和保持表面外观的方法。 章节10,局部光照(Local Illumination)。算法描绘更复杂的光源被开发。表面着色考虑到光线是由具有特征形状的物理物体发射的。 章节11,全局光照(Global Illumination)。模拟光线和场景之间多重交互的算法,...
最后简单聊一聊《Real-Time Rendering 3rd》第八章“区域和环境光照 Area and Environmental Lighting”中的EnvironmentMapping环境映射。下一篇文章,就直接开始提炼第九章“Global Illumination 全局光照”的内容。 Environment mapping(环境映射),又称Reflection Mapping(反射映射),是计算机图形学领域中使用基于图像的光照(Im...
例如我们把场景分成不同小块,然后先试着点亮所有小块来表达光照信息,然后再通过小块内部的接收者的Transport来得到间接光照的计算。 11.5.5 Dynamic Diffuse Global Illumination 这一节会开始介绍不需要预计算的一些方式。 我们之前聊过把直接接受光源的点当作间接光源的Radiosity, 这样的做法是没办法在实时渲染中使用,...

中文翻译:我们在自己的引擎中实现了光线追踪,作为一个混合解决方案,这意味着我们可以用它的光线追踪版本来替换某些系统。例如,我们的核心Global Illumination系统使用来自天空、太阳和所有位置光源的光来动态地产生反弹光。在光线追踪模式下,我们使用我们的主GI只产生反弹光,而来自天空的主光则会被光线追踪,使其在...
