I am personally happy if competition is and remains at the platform level. As a developer, supporting many different stores per platform is a huge hassle so i will go where the users are. As a user, i prefer all my games in a single library and i don’t want to give out my payment info to 10 different stores.

Loading images is one of the most fundamental things a browser does. It turns out that doing it efficiently from JavaScript is an open problem. There are multiple APIs available and the right choice depends on the browser you are targeting. ludicon.com/castano/blog/202…

Graphics Programming weekly - Issue 438 - April 27h, 2026 jendrikillner.com/post/graph…

I spent some time reverse-engineering Apple's Lossy texture format. It wasn't as simple as I originally thought, and some of the details surprised me. Check it out! ludicon.com/castano/blog/202…

I've been reverse engineering Apple's, ARM's, and ImgTec's hardware image compression formats. ARM's AFRC is the clear winner, but does native hardware compression make real-time texture encoding obsolete? ludicon.com/castano/blog/202…

KTX ETC1S files are compact, but is the quality tradeoff really worth the jarring artifacts? ludicon.com/castano/blog/202…

It's a common misconception that free healthcare costs more than paying for insurance yourself. Healthcare is roughly 2x more expensive in the USA. Money goes to insurance companies, drug companies, investors (profits) and bureaucracy instead of actually treating patients.

20years in the US, recently moved back to europe; here is my xp so far: - Ppl with those salaries in europe seem to be happier and more fulfilled than ppl with those 400k salary in the US - healthcare is as good; better in the long run, especially if self employed or in small company - decent schools will set you back 30-50k per year per kid in the US… that alone can quickly even things out when you have 2 kids - housing, property taxes, insurances are much cheaper overall - fruits and vegetable actually have taste But sure… big number is bigger than the small number

Here's some cute bounding box functions for 2D shapes. A link to a longer list in the next post.

I will be presenting "Stochastic Tile-Based Lighting in HypeHype" at SIGGRAPH 2025 Advances course on Aug 12th, see you there! Here's the full program with many cool talks: advances.realtimerendering.c…

Survivorship bias is important in engine development. If you are lacking critical features, you already lost customers requiring those. When you do a survey for your customer base, asking what they need, they don't list those missing things. Devs needing those use other engines.

...and REAC 2025 is officially done! I've closed the registration. Slides/videos will appear on our website as soon as we can process them (typically a week or two). Meanwhile, you can enjoy our break music videos on our YT channel! THANK YOU! youtube.com/@renderingengine…

Same but with Apple’s AppStore

A case study in fallacy. Your contribution to software development was a net negative, please stop.

New blog post! "Measuring acceleration structures", in which we will compare BVH costs on various GPU architectures and drivers and attempt to understand the details enough on AMD hardware to make sense of the numbers! Retweets appreciated :) Link in reply because algorithm.

.@elonmusk “some of the thing i say will be incorrect and should be corrected” It is baffling to see the likes of you and .@joerogan completely miss the fact that it takes way more work to correct bullshit than to create it in the first place, especially at this scale. Do better.

This was part of our saturday morning cartoons in France… GenX and elder millennials are built different :)
