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

good morning
For those watching in black and white, the blue is behind the brown...
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!)
Live Demo of MASt3R-SLAM this afternoon in the demo session at #CVPR2025.
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.

Great diagram.
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.
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!
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.

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.

200 hours of play in I am still addicted to Balatro!
Cool to see this.
If you like word puzzles, Bracket City is really cool:

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.
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.

Shawshank Prison reconstructed with MASt3R-SLAM... from one of the best films ever.
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.
Wow I'd like to try to understand this.
Something for @tinytapeout.com ?
Looks like a great workshop, happening in Malaga this July.
Gradually unfollowing all of the namesakes I picked up from that automatic X to Bluesky converter tool!
