Forget Superresolution, Sample Adaptively (when Path Tracing) Real-time path tracing increasingly operates under extremely low sampling budgets, often below one sample per pixel, as rendering complexity, resolution, and frame-rate requirements continue to rise. ...

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

While working on spark.js, I realized that common normal map compression formats weren’t supported in popular frameworks like three.js. I added the necessary support to three.js and wrote an article to shed some light on the topic:

YouTube video by Drew's Campfire Pushing Simulation to the Limit to Find Order in Chaos

A colleague sent me this: www.youtube.com/watch?v=8jVo...

No further comments needed, it's **very** good.

I've seen some of his videos in the past, but I missed this one. Glad I saw it.

Marcin Zalewski informed me that his blog post on real-time hair rendering using ray tracing is now available:

This is nice work, in which he compares NVidia's hardware accelerated hair to several alternatives, including Reshetov's Phantom Ray Hair Intersector.

Spinning around: Please don't! - siliceum Embark on a journey about why you should sometimes trust your OS more than yourself.

Ever wrote spin-locks or had to debug them?
I have, and I got tired of seeing (and writing) crappy ones, so I did a real investigation this time.

Spoiler: trust your OS.

Is it new or does something functionally identical already exist? I'm not sure! But I didn't come across one like this yet anyway, so here's my findings:

WebGPU Lines GPU-accelerated line rendering for WebGPU with instanced triangle strips

Still WIP, but *finally* adapted my line rendering module to WebGPU. Managed to salvage pretty much all of the logic from my old WebGL line rendering module. I know there's better algorithms and implementations out there, but I'm relatively content. rreusser.github.io/notebooks/we...

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.

A timeline visually representing the advice from my post, emphasising how dramatically and reliably having more time, with a testable build, converts to your game being better and your studio being safer.

I've been running an indie games studio for 15 years now, and it felt like a good time to boil down what I've learned into 4 pieces of advice:

I hope it's of use, not least because goddamn I forgot how long blog posts take to write.

I just released my video about the engine (and game) I've been working on.

The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible.

This is my first YouTube video and it took forever - please repost!

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.

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.
