When it comes to putting software and math to work, I&amp;#x27;ve never been more impressed than with graphics rendering pipelines. It&amp;#x27;s a realm of software I&amp;#x27;m not sure I will ever dive into, just marvel from afar. I &amp;quot;get&amp;quot; a lot of the techniques on a conceptual level, but I&amp;#x27;m not sure I&amp;#x27;ll ever grok the code that pulls it off without spending much more time than I&amp;#x27;m willing to commit to it.</text><parent_chain></parent_chain></comment><story><title>Normal 1: what normal maps are and how they work</title><url>https://www.artstation.com/typhen/blog/GMyG/this-is-normal-1-what-normal-maps-are-and-how-they-work</url></story>
