My first computer programming was Dragon 32 Basic, back in about 1982!

They're back! We're very happy to be hosting this year's Dragon Meetup. You don't have to be a Dragon owner - or even know much about Dragons - to come to this celebration of the classic Welsh home computer. www.computinghistory.org.uk/det/76704/dr...

What a nice morning to find that Alzugaray, Taher @marwantaher.bsky.social , Davison @ajdavison.bsky.social have turned ACE into a SLAM system. Since we did ACE, I was wondering whether it was possible, and I always thought who if not those folks can pull it off. 🙂 ACESLAM: arxiv.org/abs/2512.14032

good morning

I've been a Tamiya RC fan since owning and loving a Grasshopper in the 80s, and more recently built one or their RC kits with each of my kids (Hornet, LunchBox and Midnight Pumpkin!)

RIP Shunsaku Tamiya, age 90, the chairman of legendary modelmaker Tamiya. He didn't found the company, but started working there in 1958, just four years after its founding, and helped it shift from its original line of wooden models into the plastic kits it is so well known for today.

Live Demo of MASt3R-SLAM this afternoon in the demo session at #CVPR2025.

We’ve had fun testing the limits of MASt3R-SLAM on in-the-wild videos. Here’s the drone video of a Minnesota bowling alley that we’ve always wanted to reconstruct! Different scene scales, dynamic objects, specular surfaces, and fast motion.

Full draft of the SLAM Handbook now released --- available as a free PDF, with a printed version coming soon. Now including Part 3, "From SLAM to Spatial AI" (I knew it would catch on eventually), with contributions from @hidematsu82.bsky.social and me. #SpatialAI github.com/SLAM-Handboo...

Great diagram.

This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social www.sciencedirect.com/science/arti...

It's 3PM. Exactly 40 years ago the first ARM processor was powered up. It worked. To mark the occasion, a bottle of champagne was opened and the time and date was written on the bottle - by Sophie Wilson IIRC. I hope today another bottle is opened to celebrate the anniversary.

Great look at back at 2D scrolling methods in games.

Hard to believe that a decade ago, in preparation for the release of my game, I spent a month researching 2D cameras by playing through all my favorite 80s classics. If you haven't yet, check out this fun, GIF-heavy paper! docs.google.com/document/d/e...

Slow motion Galton Board. Love that Gaussian!

We were fortunate to have Jianyuan visit us at Imperial yesterday, and he gave a brilliant and thoughtful talk about 3D geometry and learning. Maybe every 6--12 months or so there is a paper in my area which really seems like something new and important, and VGGT is one of those!

Should be good!

Tomorrow in our TUM AI - Lecture Series we'll have Andrea Tagliasacchi (@taiyasaki.bsky.social), SFU. He'll talk about "𝐑𝐚𝐝𝐢𝐚𝐧𝐭 𝐅𝐨𝐚𝐦: 𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐃𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐭𝐢𝐚𝐛𝐥𝐞 𝐑𝐚𝐲 𝐓𝐫𝐚𝐜𝐢𝐧𝐠". Live Stream: youtube.com/live/1u7ahb9... 5pm GMT+1 / 9am PST (Mon Mar 24th)

Remember: the route to Spatial AI is through SLAM. Key research topics are representations for real-time fusion of measurements and priors into persistent semantic/metric scene models; and algorithm/hardware co-design for 1000X efficiency. #SpatialAI arxiv.org/abs/1803.11288

We discuss and predict the evolution of Simultaneous Localisation and Mapping (SLAM) into a general geometric and semantic `Spatial AI' perception capability for intelligent embodied devices. A big ga...

On the tram station video, VGGT fails entirely, whereas MASt3R-SLAM had done a more reasonable (albeit also not stellar) job. bsky.app/profile/chri...

Chris Offner@chrisoffner3d.bsky.social · last yr.

This underground tram station also shows some drifting, and some scene elements float in places where they don't belong. The overall layout is correct though, unlike in the (much longer) video of the ETH main building that I showed first.

Visual Geometry Grounded Transformer (VGGT) predicts cameras, point maps, depth maps, and point tracks for up to hundreds of images in less than a second on a H100 GPU. github.com/facebookrese...

Cool to see this.

If you like word puzzles, Bracket City is really cool: bracket.city The clues are cleverly nested in a way that looks like Lisp code! (Via the @recomendo.bsky.social weekly newsletter.)

Many interesting tests of MASt3R-SLAM on prerecorded videos.

Chris Offner@chrisoffner3d.bsky.social · last yr.

I tried MASt3R-SLAM on this challenging sequence but it struggles. I'll have to see whether I can get it to produce better results on this one.

Aria Gen 2 is very impressive, with fully onboard SLAM and various other perception all within a 75g device with an hours-long battery life. Processing on custom silicon. Congrats to the Reality Labs team.

Today, we're excited to announce the next step in the Project Aria journey: the introduction of Aria Gen 2 research glasses.

Shawshank Prison reconstructed with MASt3R-SLAM... from one of the best films ever.

Eric Dexheimer@ericdexheimer.bsky.social · last yr.

Here's a reconstruction of a movie establishing shot

I remember seeing this drone video a few years ago and thinking "we'll never run SLAM on that".... but here it is, complete with dense reconstruction (single camera, unknown calibration, no IMU). MASt3R-SLAM is absurdly robust.

Open source code now available MASt3R-SLAM: the best dense visual SLAM system I've ever seen. Real-time and monocular, and easy to run with a live camera or on videos without needing to know the camera calibration. Brilliant work from Eric and Riku.

Not one VC would ever fund a startup to do the kind of hardcore optimization work that DeepSeek did. Every VC firm should be asking themselves why.

In other news, IQ is on Bsky now and you should follow him.
