A dream was always to make a "cloud" tool. Now over the last 1-2 years I tried to build smth on and off. Now I made it work in the browser. WARNING! Depending on the settings it can take a lot of GPU power, so be careful. Only for people who know what they're doing. artbuddy.urlich.ch/cloudbox/

A bit silly blog post today: can you find a vector NOT orthogonal to a bunch of other vectors? Somehow the answer is deeper than it sounds lisyarus.github.io/blog/posts/c...

New blog post! Kinda math-heavy this time, but I wanted to share about this weirdly fascinating things called quiver representations that generalize stuff from basic linear algebra to wild unsolvable problems 🤩 lisyarus.github.io/blog/posts/q...

Vulkan Memory Allocator new release 3.4.0 with many additions, improvements, and fixes. If you use code from the "master" branch, you already have them, but if you rely on the official Releases, you should upgrade. This one gathers >1 year of development. github.com/GPUOpen-Libr...

I implemented multiple fixes & improvements in Vulkan/D3D12 Memory Allocator libraries, on my fork for now. If you use any of these, please give it a try so we validate they work fine before I turn them into official releases. github.com/sawickiap/Vu... github.com/sawickiap/D3...

(🧵 1/6) Recently I've been working on an HLSL interpreter, which can execute shader code entirely on the CPU github.com/pema99/HLSLI... I used it to make a cute little interactive debugger demo. You can try it yourself at pema.dev/hlsl/

New Paper🙂 Nanite has shown that small triangles can be rendered fast in compute, we're exploring how fast for large meshes with up to 18.9 billion triangles, without the need to precompute LOD structures. Paper: github.com/m-schuetz/Cu... Source: github.com/m-schuetz/Cu...

INTRODUCTION TO SPHERICAL HARMONICS FOR GRAPHICS PROGRAMMERS finally done. gpfault.net/posts/sph.html

meshoptimizer 1.1 is out! github.com/zeux/meshopt... Featuring two new major features, meshlet topology compression and opacity micromaps, as well as a few smaller features and improvements! More information in the infographic and release above :) Boosts and repository stars are welcome!

I am not sure I can overstate how useful this tool is. Not sure if your game is paging out GPU-memory to system-memory? Well now you know :) github.com/jonasmr/demo...

Hey, I wrote a thing about AI in astrophysics ergosphere.blog/posts/the-ma...

I have a brand spanking new "Loose Lexer/Parser" for C++ that can pull an entire AST from large code bases orders of magnitude faster than a compiler can. Got some good uses for that coming up!😍

I finally wrapped up the second post on the series about micro-shadowing. On this one I go over a basic approach based on a microsurface, and I show results for different materials and lighting conditions. irradiance.ca/posts/micros...

FASTBuild v1.19 has been released, including: * LightCache supports Clang & GCC for significantly faster cache operations * Support for Ctrl+F7 integration with Visual Studio * BFF syntax enhancements * Bug fixes Details: http:// fastbuild.org/docs/changelog.html Big thanks to all contributors!

Interesting paper showing great results for replacing standard low-res rendering + temporal upsampling (DLSS) with high-res GBuffer + adaptive sampling. Makes sense given rising costs of lighting computations vs GBuffer. arxiv.org/abs/2602.08642

I have procrastinated on writing so much that I wrote an entire document on writing tips: cseweb.ucsd.edu/~tzli/writin... Probably not much is new but I find I still need to repeat the same things to my students regularly. Will update this document over time hopefully.

this point came up in a discussion some months ago which made me realize that supporting proper lambdas in hlsl would mean this "anyhit shader" logic could be passed in as lambda and inlined with the "hidden" code that does bvh traversal. maybe that'll happen some day..

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming. graphicrants.blogspot.com/2026/02/nani...

This was a fun quick experiment: Using an old photo I took in the forest, I used ml-sharp to generate gaussian splats from it, voxelized it in my toy renderer, relit the scene dramatically. #rendeting #metalrt

cseweb.ucsd.edu/~tzli/novelt... I gave an internal talk at UCSD last year regarding "novelty" in computer science research. In it I "debunked" some of the myth people seem to have about what is good research in computer science these days. People seemed to like it, so I thought I should share.

-- JOB SEARCH POST/RT APPRECIATED -- Hello everyone! I am available for work (full time position/internship) anywhere in the world with priority going to the EU, starting June 2026. 🧵

My "How to Vulkan in 2026" @vulkan.org #Vulkan guide is now publicly available at www.howtovulkan.com I still consider it a preview, though I'm mostly happy with it and only plan on changing minor things and incorporating some feedback.

As my holiday project, I went back to my retro engine project after a long time. Decided to add something modern, so here's meshlet rendering on Voodoo 2: youtu.be/VOv8JqUZstQ

I got the first post about direct lighting material occlusion up on my blog. On this one I go over the commonly used micro-occlusion approach and its limitations, and I start digging into micro-shadowing as an improvement. irradiance.ca/posts/micros...

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... 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".

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them. irradiance.ca/posts/

Funding: if your mid/large business uses Dear ImGui - and maybe you are approaching end of year budget/planning etc. - please consider reaching out (PM/email) so I can help you help Dear ImGui !

New blog post! Behind the scenes of some of the techniques involved in making our last PC demo 💫 gboisse.github.io/posts/this-i...

i had a chat with lukasz and @antovsky about gamedev and stuff, if youre into that sort of thing! the middle hour is the juiciest but its all fantastic, ofc ;) youtu.be/mFBmoCv5EcQ?...
