A Hacker News thread discusses Inigo Quilez (iq), a legend in computer graphics, demoscene, and shaders. A former Pixar intern, ykl, recounts iq's work on Wondermoss, a procedural vegetation system for the movie Brave. Wondermoss generated vast, lush forests with minimal memory usage by utilizing REYES rendering. A fun detail was that the default random seed used iq's phone number, subtly immortalizing it in Pixar films. Commenters praise iq's talent and his contributions to ShaderToy, raymarching techniques, and learning resources. His "Elevated" intro is highlighted as an example of demoscene artistry, achieving amazing results within 4KB. Several users share links to iq's videos, including tutorials and podcast interviews. One user recounts how iq's material made a big difference during cancer treatment. Overall, the thread showcases the high regard the community has for Inigo Quilez's technical skills, creativity, and contributions to the field.

Wondermoss was a spectacular piece of tech. Every single forest scene and every single piece of vegetation in Brave is made using Wondermoss, and it was all procedural- when you'd open up a shot from Brave in Menv30, you'd see just the characters and groundplane and very little else, and then you'd fire up the renderer and a huge vast lush forest would appear at rendertime. The even cooler thing was that since Brave was still using REYES RenderMan, iq took advantage of the REYES algorithm's streaming behavior to make Wondermoss not only generate but also discard vegetation on-the-fly, meaning that Wondermoss used vanishingly little memory. If I remember correctly, Wondermoss only added like a few dozen MB of memory usage at most to each render, which was insane since it was responsible for like 95% of the visual complexity of each frame. One fun quirk of Wondermoss was that the default random seed was iq's phone number, and that remained for quite a number of years, meaning his phone number is forever immortalized in pretty much all of Pixar's films from the 2010s.
iq is one of the smartest and most inspiring people I've ever met.
