When I attended WWDC 2018, one of Pixar's lead lighting engineers gave a high-level presentation on the intertwining of math/physics/art to shade animated scenes in their movies. I would love to walk through one of their internal scene files and inspect all the polygon's on Woody's shirt. It's a fascinating intersection of programming not many people relate to.
Unfortunately I couldn't find the video either but it was fairly similar to the TED talk you linked (just longer and had slightly more "internal" details).
