    A new version of the unofficial Ray Tracing Gems PDF is up, with little, useful fixes Chapters 3, 25, and 27. - me, I'm happy there hasn't been much more errata than what's there after a year:

    Wrote a post about normal reconstruction, described a method based on 's SDAA idea, which is more costly but also more accurate than 's method.

    Happy 2020! In the new decade I decide to write blogs again, and here is the first article: Draw Anti-aliased Lines with Geometry Shader.

    1. I was offered my current job at the very start of 2010. Sometimes people ask me how to get a job in tech and honestly, no clue. This is how I got mine. ¯\_(ツ)_/¯

    Terminology (Ab)used in 3D Vector Algebras I really don't know where all the confusion comes from. Seems crystal clear! 🤨

    On x86, the general purpose and SIMD registers get most of the press, product placement opportunities and essentially all of the hot after party invites. Let's shine a low level uarch light (what?) on their newly arrived sibling: the mask (k) registers.

    Find of the day: this code. That's the entirety of it. (I'm sure it did something at some point, but now it's just wat)

    I wrote a short blog post about RGB/XYZ color conversion matrix accuracy. The numbers in FGED2 differ a little bit from those published in other books.

    Neat shadertoy-like webgl framework for prototyping raytracing algorithms. Good range of tutorials to get you started as well.

    Clang format might reduce the performance of your mission-critical toupper() loop by 4x. Act now before it's too late.

    Hey! I made some impossible geometry! Not only is the interior different for each face... but there's also 5 of them!? Stencil shaders are cool. ✨👀 (see thread for a mini-breakdown)

    Lovely indirect lighting method , (Vulkan branch)! I think that a good SSAO on top would give a very convincing result.
