Render Graph是什么？

近期学习到Render Graph这个概念，之前在看UE4的RDG的时候也看到了这个相关的概念，今天查找了一些相关资料，记录一下。

Frame graphs are a design pattern for handling complex rendering pipelines, which are currently used in industry. Their usage is motivated by handling barriers, queue synchronization and memory aliasing in the background by abstracting the rendering pipeline of a frame on a higher level.
