New random sampling method for three-gpu-pathtracer: blue noise dither sampling! It offsets a common random sequence for ALL screen samples, yielding a cleaner image in just a few samples. Screenshots are single sample scrambled sobol vs blue noise. Small writeup below👇
One of the weirder things I made for Keeper was a faux fractal generator in substance designer. These were used as alphas for sculpting and some VFX. #gameart
Sharing my tiny #voxel editor app that I've been working on for the past year: polycube.app It has nice-looking color sliders, three different brushes and a #raytracing renderer with a built-in denoiser ✨ Looking to keep updating it, still so many things on the to-do list! 📋

My erosion filter is out! Video, blog post, and shader source. It emulates erosion without simulation, so it's fast, GPU friendly, and trivial to generate in chunks. Explainer video: www.youtube.com/watch?v=r4V2... Companion blog post: blog.runevision.com/2026/03/fast... #ProcGen #vfx #GameDev
The #WebGPU global illumination engine is getting somewhere, now with volumetric light shafts (00:58) and fully destructible environments. Sorry about the mouse cursor, that's how you know it's real, AI would _never_.
I think most raytracing effects and denoisers don't really think about needs of fast games like shooters. For my RTGI denoiser, i put in a lot of care to get an immediately readable and stable image from the first frame after dis-occlusion. its very satisfying.

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
Coloring a fractal is interesting in itself. Finding good colors is tricky. Applying them to the "right parts" is tricky. Here's a comparison of off-white vs a value that's displaced relative to the folding for each iteration (then mapped to a color ramp). #fractals #rendering #metalrt
Ok, so I'm completely stuck trying to debug this. Left is pathtraced reference, right is my realtime renderer. Top row are metals, bottom row are dielectrics, and roughness goes from 0 to 1 left to right.

New blog post! (yep, at New Year's Eve.) A short detour into a fun one-liner shading model I use for clouds in my game 🥰 lisyarus.github.io/blog/posts/a...
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".
