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.

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...

@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

@guerrilla.bsky.social just announced Horizon's #MMORPG in cooperation with NCSoft. Please, please, please be great: www.youtube.com/watch?v=bN-N...

Uh-oh: Spiraling down the #nixOS road. After watching this video (www.youtube.com/watch?v=dsl_...), I thought I should also have dinner. Dinner with the penguins and the snowflakes. Let's see how far I am getting with this. Not sure I am ready.

Honestly flabbergasted by all the amazing work presented at #BCon25. It’s nice to see what everyone makes out of Blender and how far contributions can go. Definitely one of the nicest communities to be around. Superb talks, nice location, great people. Can’t wait to see you all next year again 🧡🎉

First @blender.org Conference in person. Let’s gooooooo!

It's a wrap! Thanks for the ride @blender.org! I had a great time and learned a lot of stuff. Thanks to Omar and Habib for the mentoring, and I will definitely continue to contribute to Blender. :) I'll be around at BlenderCon this week and happy to chat :)

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code. (And yes it's really been 10 years 👴). therealmjp.github.io/posts/ten-ye...

I was today years old to discover that C++ also has: - && `a and b` - || `a or b` - !a `not a`

Hey #ECVP, we got our colleague @joshuamartin2902.bsky.social on BSky! Give him a follow! :)

Pretty nice city for a pretty nice conference (jubilee).

Hey #ECVP, Thanks for the nice conference and the splendid organization. First ever conference and really enjoyed all the chats I had with so many people. Also, thanks for stopping by my poster and all the questions you brought :) Personal highlight: Roland’s keynote. Gave me a sense of belonging.

G'day #ECVP! Today, three more colleagues present their posters. 38: @celinehonekamp.bsky.social will introduce you to dual adaptation in the temporal domain. 48: Tarek will present a relative depth experiment conducted on the multifocal display he built.

Good morning #ECVP! Today, two of my colleagues are presenting their posters in the morning and afternoon session 🎉 Lina will introduce you to (mismatching) causal relationships and @lreining.bsky.social will introduce you to MooneyMaker, a Python package to create ambiguous two-tone images.

I'd be glad to see a lot of people at our poster on Tuesday, August 26th, 10-11.30am at #ECVP2025 and tell you more about which cost functions shape your behavior in sensorimotor decision-making!

#ECVP2025 be ready: my poster on repeated exposure to delay in two different tasks is up on Thursday 15:30-17:00 (No 38) Come and say hi

I won't get to join you all at #ecvp2025 @ecvp.bsky.social this year because I'm on holiday in Australia... but my lab is there in force! Please do go say hi, and check out my students' and postdocs' amazing work! @ben.graphics @lschmittwilken.bsky.social @lreining.bsky.social
