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. πŸ™‚

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.

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.

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.

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!

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

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.
