It is an understatement how much "fun" in your tooling can drive your motivation to get stuff done. I like C++, but sometimes writing it in my free time can feel very demanding. I started writing Zig last week, and it saves me from a lot of headaches that C has. Zig is literally: WYSIWYG. 1/n

Pretty cool report. www.youtube.com/watch?v=XN_Z...

Happy to announce that after VSS, I will be giving another talk this year @ecvp.bsky.social. In my talk, "Applications of Physically Based Differentiable Rendering in Vision Science", I'm going to talk about the challenges and potential of PBDR in vision science, framed in our experiences. #ECVP26

What is upppp!? AION 2 announcement for September this year. And Guild Wars 3 for next year's fall. 😱 Seems like I will finally get another life span as a spiritmaster in the sequel in my first ever MMO. www.youtube.com/watch?v=IZ_z... www.youtube.com/watch?v=ITPz...

New side quest? 😱

Zig Hydra delegate is up and running. To be fair, it looks "better" than the Rust solution, but that is probably me writing non-idiomatic Rust (not that I claim I am proficient in Zig either).

I'm annoyed @patagonia.com. If you start suing people who are environmentalists, activists, and getting people off-screen by encouraging them to go on a hike, you are very wrong. I can already smell Yvon's disappointment. You can do better. Drop the lawsuit. www.theguardian.com/culture/2026...

I’ve seen @andykelley.bsky.social called a lot of nice and ugly things. But damn, he makes a whole lotta sense if you give him the time and space to explain himself: www.youtube.com/watch?v=iqdd... We need people like him in today's world.

After reading www.janwalter.org/jekyll/rende... I wanted to write a general @openusd.bsky.social Hydra delegate bridge that other languages can bind to. After a couple of weeks, I finally have two tests up and running: Jan Walter's pbrt-rs and a custom Rust render pass. 1/n

I'm making Cozy Country, a game where you paint beautiful landscapes then step inside and explore the world you've created. Coming to iOS, Android, and Steam❤️ Wishlist on Steam: store.steampowered.com/app/4690240/...

You can now specify the colour for insertions and deletions. Strikethrough in math environments falls back to using \cancel, because strikethrough does not render correctly in math environments.

Friendly reminder; nice to e-meet you on Monday!

I usually don't get to write Rust. Today I sat down and wrote a tool I needed anyway (which is the best use case, I guess?). A LaTeX diffing tool to produce PDFs from two sources (in this case, a branch, file, or directory). So here's pdfdiff: github.com/pixelsandpoi... (also available on crates).

Nvidia is giving Rust some attention: github.com/NVlabs/cuda-...

fuck sam altman forever for taking away the last places where we could engage in good faith: the creative arts, which should be a testament to human ingenuity. i am so mad that everything i read or listen to or admire is now tainted with doubt. do you understand? he is a thief of joy and i HATE HIM

I hope many more will follow.

More personal renderer tales: Unidirectional path tracing + manifold next event estimation Wanted to see how far I can get with caustics without using Photon mapping. (excuse the sloppy water surface, which is procedural itself)

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

Today's my first day of the second year of my doctoral degree and I want to share some things I struggle with and things I learned throughout the first year. Just a brain dump and no particular order. Feel free to add yours :) 1/n

Offline rendering tales. Just implemented a BVH in my own renderer using the surface area heuristic and iterative traversal. Meanwhile, brute force still hasn't finished (30+ mins).

Been trying to implement OpenPBR (academysoftwarefoundation.github.io/OpenPBR/) in Mitsuba. Here are some preliminary results with the spectral renderer. The geometry is the standard shader ball available in @openusd.bsky.social. It's pretty neat to visualise different light-surface interactions.

word.

Found something potentially useful for the neural graphics folks: arxiv.org/abs/2603.08824 TL;DR: Package finds soft surrogates for otherwise non-differentiable functions. Has an implementation for Torch: github.com/a-paulus/sof... & Jax: github.com/a-paulus/sof...

“In our culture, preferring an algorithm to a trainee feels like a betrayal of the academic mission.” That’s because it is. www.science.org/content/arti...

@godotengine.org received the infamous Nvidia RTX branch: github.com/NVIDIA-RTX/g... A path tracer is included among other things.

Adobe open sourced their OpenPBR implementation: github.com/adobe/openpb...

Final Fantasy XVI 14/10. Onto the expansions!

Ray Tracing using HIP arxiv.org/abs/2603.00292

Is there anyone by chance who uses colemap-dh on a split columnar keyboard and has a bulletproof layout for symbols? I still struggle to find a comfortable symbol layer.

New bugfix is available for: github.com/pixelsandpoi... Now nested plugins serialize/resolve correctly in your scene, so you can start using BlendedBSDFs :)

Fly through of part of a Keeper level directly in the Unreal Engine editor. Part way through I turn on all of the game objects the player doesn't see -- it takes a lot to make games work.

I was today's years old: github.com/rlguy/Blende...

A couple of great Slang Shader talks are ready for viewing:

The Vulkan Working Group has published, Building a Simple Game Engine, a new in-depth tutorial for developers ready to move beyond the basics and into professional-grade engine development. Learn more: www.khronos.org/blog/new-vul... #vulkan #tutorial #programming #gpu #gameengine

Late to the party, but… I just had the most cinematic encounter in my entire video game career fighting against a primed Titan in #FFXVI. Good job @square-enix-games.com, I’m flabbergasted.

G'day! I've just published a new version of mitsuba-scene-description to GitHub and PyPI: github.com/pixelsandpoi... I've changed the generation process, so you no longer need to manually clone and build the API yourself. The Mitsuba plugin API will now be generated during package build. 1/x

Excited to share that GPU Zen 4: Advanced Rendering Techniques is officially out. This volume features work from some of the most visually impactful projects of recent years, including #AssassinsCreed , #DOOM , #StarwarsOutLaws and NVidia's Zorah. And a killer cover :)

Unfortunately, I left Claude fixing Arxiv compilation errors. Apparently, it changed a citation in the process (that was right in v1 of the paper). I am currently reviewing all the citations now again by hand and preparing a new version that fixes these. I will also post them here: 1/x

Not gonna lie, I'm impressed by Unreal's new layered material system (Substrate): www.youtube.com/watch?v=d1nc... Reminds me a lot of Wenzel's and Andrea's work on layered BSDFs, but for real-time graphics. Happy to see it in Unreal. www.cg.tuwien.ac.at/research/pub... rgl.epfl.ch/publications...

Sorry for the wait (been to China for 4 weeks between the years), but I finally managed to update the pre-print with more results and the code is now also available on: github.com/ag-perceptio... If you run into issues, let me know.

Happy to announce that I will be giving a remote talk @vssmtg.bsky.social this year. I will be presenting our recent pre-print MRD: Metamers rendered differentiably (arxiv.org/abs/2512.12307). Happy to take questions before the presentation in May, or live during the online Q&A. #VSS2026 #VSS26

That’s cool. 🤓

Hi fellow #Neovim users! I faced some problems with the LSP and #Slang within Neovim and finally figured out how the files need to be generated. The solution is provided in my first Neovim plugin I've written (so bear with me), available here: github.com/pixelsandpoi...

Pretty cool that we can now use glTF for Gaussian Splats: www.khronos.org/news/press/g...

Legit super excited about this work coming out. My amazing doctoral student @ben.graphics has been working on an idea to use physically based differentiable rendering (PBDR) to probe visual understanding. Here, we generate physically-grounded metamers for vision models. 1/4 arxiv.org/abs/2512.12307
