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.

Eric Dexheimer @ericdexheimer.bsky.social · Feb 25

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.

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

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.

Itay Keren @untame.com · Nov 15

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.

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!

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

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

If you like word puzzles, Bracket City is really cool:

The clues are cleverly nested in a way that looks like Lisp code!

Many interesting tests of MASt3R-SLAM on prerecorded videos.

Chris Offner @chrisoffner3d.bsky.social · Feb 27

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.

Andrew Davison @ajdavison.bsky.social · Feb 28

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.

Introducing Aria Gen 2: Unlocking New Research in Machine Perception, Contextual AI, Robotics, and More

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

Here's a reconstruction of a movie establishing shot

Andrew Davison @ajdavison.bsky.social · Feb 25

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.

Eric Dexheimer @ericdexheimer.bsky.social · Feb 25
