Captured Rocco in 3D using an iPhone. Aligned on device in 5 seconds and processed through Brush - the most accessible way to create 3D splats! Alignment can use some work, but Brush did a great job on the fur. Great work @arthurperpixel.bsky.social !

After nearly a decade of development, I am very excited to finally announce Desolus! Explore a city of Gothic architecture torn between past and future in Desolus, a first person puzzle game. www.youtube.com/watch?v=HxfV...

Reminder that if corporations are people, the reverse can also be true. You can just pretend to be a corporation, and do practical jokes like donate to #blender fund or something.

Testing the Insta360 X5 @insta360official.bsky.social for gaussian splatting. Kensal Green Cemetery, London. Trained in Brush by @arthurperpixel.bsky.social and running around with a PS5 controller in Unity using Aras P's plugin. #gaussiansplatting #3DGS

It feels like video games have become actively LESS like Third Spaces in the past 20 years, and more like eternal fucking shopping malls, JUST as physical space has. This is monstrous, and it's such a waste.

The Himalayan Glade at Wakehurst Gardens, Sussex. Captured with the Qoocam 3 Ultra and trained in Brush by @arthurperpixel.bsky.social. The new MCMC method added to Brush is amazing for large scale scenes! github.com/ArthurBrusse... #gaussiansplatting #3DGS

Mausoleum of Habib Bourguiba in Monastir, Tunisia. Trained with Brush by @arthurperpixel.bsky.social using it's new MCMC-like method, on my Macbook! Rendered in Unity with Aras P's plugin and Deckard Render by @olixoliver.bsky.social. github.com/ArthurBrusse... #gaussiansplatting

A thread of thoughts on radiance fields, from my keynote at 3DV: Radiance fields have had 3 distinct generations. First was NeRF: just posenc and a tiny MLP. This was slow to train but worked really well, and it was unusually compressed --- The NeRF was smaller than the images.

We often use discretization to approximate continuous laws of physics, but it also goes the other way: You can use continuous equations to approximate the behavior of discrete systems! Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]

I've now published my blog post, "I want a good parallel computer." raphlinus.github.io/gpu/2025/03/... . Thanks much to all the feedback on the draft, I'd like to think I've clarified some things that might have been confusing.

Probably the best Brush (github.com/ArthurBrusse...) reconstruction I've seen so far, many thanks to @gradeeterna.bsky.social!! www.youtube.com/watch?v=yGl0... Try it interactively here arthurbrussee.github.io/brush-demo/?... if you'd like to melt your GPU a bit ;)

I’ve released a new version of my 3D reconstruction tool, Brush 🖌️ It's a big step forward - the quality & speed now match gsplat, and there’s a lot of other new features! See the release notes github.com/ArthurBrusse... Some of the new features:

Fast3R: Towards 3D Reconstruction of 1000+ Images in One Forward Pass Jianing Yang, Alexander Sax, Kevin J. Liang, Mikael Henaff, Hao Tang, Ang Cao, Joyce Chai, Franziska Meier, Matt Feiszli tl;dr: one more multiview-transformer decoder for DUST3r encoder. Optimized arxiv.org/abs/2501.13928

We just dropped CAT4D, text to dynamic 3D models that you can render in real time. Not posting a video because Bluesky is garbage in this respect; go straight to the real time viewer on a desktop browser and look around. The cat kneading dough is my favorite. cat-4d.github.io

This project blew my mind! It looks just as good as 3DGS but it has no per-scene optimization or reconstruction. Every frame is generated *from scratch* and it nevertheless runs in real-time. quark-3d.github.io

Khronos will oversee the open-source Slang shading language and compiler www.khronos.org/news/press/k... This is big. Slang is cross-platform, backward-compatible, and trivial to port to. It supports differentiation/gradient computation as the first-class citizen, allowing to merge ML and graphics.

I recently gave a tutorial on the DUSt3R paper (web: dust3r.europe.naverlabs.com, paper: tinyurl.com/5t2ks575, code: github.com/naver/dust3r) in a research group meeting. In case you missed it, didn’t understand it or would like to hear some perspectives on why it’s such a cool idea, read on… 1/23

Bluesky is finally usable now that this is here

Have such a soft spot for GPU particles - a demo from Aras Pranckevičius for the Hot New DX11 Unity put me onto GPUs! Guess that's how I got to gaussian splatting :') Anyway such a good video pls more particles Acerola do splats Acerola!!

new video is out now going over the particles! youtu.be/1L-x_DH3Uvg

THE SIMPSONS PARADOX

news.ycombinator.com/item?id=4193... Hackernews has arrived and only 1 bit of pedantry so far, I'll take it!

Also hello new blue-er place, I hope you don't become a tire fire or a linux-y flamewar space, I really could do with a new healthier dopamine slot machine

I shared this on the Bad Twitter, but now that I'm on The Good Twitter... Just open sourced Brush🖌️, a new, super cross-platform Gaussian Splatting engine! It can train and render on any platform, or even straight in your Browser github.com/ArthurBrusse...
