NEE with a single light source. There's still some bias since subsequent paths don't apply MIS weights if the indirect sample hits the light source... and probably other sources of error as well. )

Getting closer to feature parity with the linux port. It's going to be very fun.. to find and fix all those hacks/oversights.

With @briankaris.bsky.social winning this year’s SIGGRAPH Practitioner award, it’s a great time to repost his HPG 2022 keynote, which is one of the best talks I’ve ever seen. The tech is cool, yes, but what makes the talk is Brian’s approach to R&D and invention.

RGB rendering is founded on lies and perpetuated by misconceptions about the practicality of spectral rendering. My new blog post series describes a spectral GPU path tracer. Part 1 focuses on how to make it work with existing RGB assets.

OPEN SCIENCE IS THE FUTURE!
Very pleased to see the Association for Computing Machinery (ACM — the parent organization to my “home” conference SIGGRAPH) has announced it is transitioning to full open access by January 2026!!

New blog post discussing Async Compute, various experiments with pairings and task overlapping and performance impact. interplayoflight.wordpress.com/2025/05/27/a...
Async compute all the things
GPUs make work parallelism very easy by design: each drawcall/dispatch shader instruction operates on batches of vertices, pixels, threads in general at the same time automatically. On the other ha…

A little write-up on my current rendering project: bjarkede.com/posts/2025/s... Short introduction to the renderer and how I sample distant area lights using blue noise.

A friend wrote a three-part retrospective on Quake III Arena for its 25th anniversary: myt.playmorepromode.com/blog/ It covers RHI implementations, OIT, DoF, volumetric lighting, his history with Quake III, and lessons learned. It's a great read.

It's an any% speedrun of our GPU-driven rendering, shadows, global illumination, water, and DoF, involving a few weird tricks.

Last month I presented Gigi to the Graphics Programming Conference in Breda, talking about the history and motivation of Gigi, as well as implementation details.
My talk, and the rest, are now available on youtube.
The conference was amazing.
