PyRoki: new open-source toolbox from our lab.
Makes robot kinematics optimization easy with python—flexible autodiff with (my favorite part) a Levenberg-Marquardt solver that properly handles rigid 3D transforms via Lie groups + an awesome visualizer 🔥

Shape of Motion was originally led by
@qianqianwang.bsky.social , Vickie Ye, and
Hang Gao. Qianqian is on the academic job market, and Hang is on the industry job market—they are both amazing!
SOM code updated with MegaSAM processing + other updates like 2DGS and camera optimization and more!: github.com/vye16/shape-...
This revamp on SOM only possible thanks to
Weijia fantasticoven2.github.io, who is looking for PhD positions!!
MegaSAM code: github.com/mega-sam/meg...
Congrats to @zhengqili.bsky.social
and the team for leading yet another big step forward🎉!
Exciting news! MegaSAM code is out🔥 & the updated Shape of Motion results with MegaSAM are really impressive! A year ago I didn't think we could make any progress on these videos: shape-of-motion.github.io/results.html
Huge congrats to everyone involved and the community 🎉
Late to post, but excited to introduce CUT3R!
An online 3D reasoning framework for many 3D tasks directly from just RGB. For static or dynamic scenes. Video or image collections, all in one!
