《Physically Based Rendering: From Theory to Implementation, Third Edition》这本书主要专注离线渲染，实时渲染只能用到里面很少的一部分。PBRT3现已开放Web版全文免费阅读，非常良心：http://www.pbr-book.org/3ed-2018/contents.html。
《Real-Time Rendering 4th》中PBR的相关章节，个人认为是非常不错的资料。
《Physically Based Shader Development for Unity》，主要是PBR在Unity引擎中的使用，而且是以Surface Shader的方式，准入门级，比较浅。
