You'd think that in Unity "how do I do a square root?" has a simple answer. It does not! Here's a blog post about various complexities of math related codegen, precision and performance in Unity: aras-p.info/blog/2026/06... #unity
New blog post is finally up: (Ab)using Shader Execution Reordering.
A bit of outside the box usage of SER (for better or worse).

Cheating as well, since this is fairly recent. My midlife crisis is this now.
So! Back in 2011, BitSquid made a "Header Hero" tool for C/C++ codebase header analysis. I did some updates to it in 2018. But now that I'm on Linux, I rewrote the UI (now it works on Win+Mac+Linux), did some performance improvements, and some other tweaks. Here: github.com/aras-p/header_hero
'Syntonic Dentiforms' demo remake by @aras-p.bsky.social is using sokol for rendering and audio :)

📣🍏 Tiny Glade now runs on macOS! Mac users can finally pet the sheep (um, the rest of the game should work too 🤭)
You'll need one of them "Apple silicon" Mac 'puters, like M1, M2, etc. or MacBook Neo.

Here’s a cool talk from GPC 2025 on the architecture of Blender’s Cycles renderer. There is no one right answer to designing a renderer; as a rendering engineer, I really like seeing how different renderers choose different tradeoffs to meet user needs:

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Graphics APIs and shader languages have significantly increased in complexity over the past decade. It’s time to start discussing how to strip down the abstractions to simplify development, improve pe...
