A Texture Lookup Approach to Bézier Curve Evaluation on the GPU https://jcgt.org/published/0015/02/01/ New published paper! The premise is that you can offload polynomial evaluation to the texture sampling unit, which can be useful for improving execution times if you are compute bound. Readers of my blog may remember this from ~10 years ago. It has been improved with Seiler interpolation to be able to do higher order curves in lower dimensional textures.

Last night I dreamed of "Catalina Chicken". I described it to my wife and we cooked it for dinner.

RE: https://mastodon.social/@RuthMalan/116893028743364880 I was feeling despair and burn out professionally, starting ~a year ago. The AI cultism, that it was starving everything else, and personally feeling like I was at the apex of what I could hope for, and it wasnt that great (cant share why). The job hunt reminded me that small and mid sized companies are friendlier and more human. Also there are plenty of places that value things that arent ML, they are just not as loud about it. I believ...

I left EA yesterday and am now officially on summer vacation, woo! After a few weeks ill be joining Bolt Graphics, a startup GPU company, aiming to put the graphics back into graphics processing unit. It's a small company with a bold but respectable plan. Wish me / us luck! https://youtu.be/-fZM9wOvbh0?is=HRgzejXgpo5cd9Yw

What To Learn To Be A Real Time graphics Programmer https://blog.demofox.org/2026/07/01/what-to-learn-to-be-a-graphics-programmer/ I wrote this up over lunch and it's surprisingly popular so sharing over here too.

I cannot fricken wait for subnautica 2 to come out. Im bummed that its early access and not the full game, and ive actually stopped getting early access games as a rule because it ruins the experience for me, but ill make an exception for subnautica.

Hey All, I made a header only C++ library where it&#39;s 1 line of code to init, then you can start writing to pixels on the screen. I call it thirteen.h, as it is inspired by the simplicity of the 13h days. Examples include a mandelbrot viewer and a playable mine sweeper game. MIT licensed. https://github.com/Atrix256/Thirteen

To me, the craziest part of gradient descent is that you take derivatives of a bunch of different parameters, some derivatives are bigger than others, and those sizes just happen to be the right proportion. It seems like mixing multiple parameters to optimize should be some non linear thing. Sure the gradient is only guaranteed linear for infinitessimal lengths, but still. Seems weird.

Iran seems to be using the same social media strategists as Wendy&#39;s and they aren&#39;t wrong to do so.

My son and his class mates are using proxies to get around game websites being blocked at school, and they are learning how to talk to LLMs to make them do what they want, even against &quot;previous instructions&quot;. I couldn&#39;t be more proud.

Thirteen.h now has controller support on windows. https://github.com/Atrix256/Thirteen Thirteen.h is a header only C++ library that inits a window in one line and gives you pixel access. It also gives frame time, keyboard and mouse state, and now controller state for up to 4 controllers, letting you quickly create interactive graphical applications. It supports Windows, Mac, Linux and WASM. If anyone is interested in implementing controller support for Mac, Linux, or WASM, it would be very muc...
