Hey, thanks for writing the article! My nitpicks aside, I learned a lot. I'm always interested in reading more about spectral rendering. > I’m, admittedly, highly biased as I work for Wētā FX, a high-end visual effects vendor That's fair. I can see it being a stated goal of PBR at Weta. However, I'm at the extreme other end of the rendering spectrum. I work with WebGL (I contribute a lot to three.js) and being indistinguishable from reality is most assuredly NOT a goal of a real time in browser rendering engine. I mean, we can dream. But it will be a long, long time before we could realize that dream so our time is better spent finding approximations that can work even on a midrange mobile device.
