1/ Excited to present FunREC: "Reconstructing Functional 3D Scenes from Egocentric Interaction Videos" at #CVPR2026!

FunREC builds functional, interactable 3D digital replicas of real-world environments from a single egocentric interaction video.

👇 Here's me turning my own kitchen into a functional 3D digital twin, just by interacting with it.

5/ To motivate research on functional 3D scene understanding, we also introduce two new 4D datasets:

RealFun4D — 351 in-the-wild human-scene interactions in 60 real-world indoor spaces
OmniFun4D — 127 photorealistic simulated interactions in 12 synthetic indoor spaces

Both come richly annotated: RGB-D video, camera poses, hand & interacted part masks, 6D part poses, articulation parameters, interaction intervals, action text descriptions, and full 3D reconstructions of the static scene + every moving part.

Had a fantastic time at @zurichnlp🇨🇭amazing audience and discussions!
Showed how superquadrics can represent the world, with:
- SuperDec https://t.co/rGIn4Ia6qF
- SuperFlex https://t.co/ZVaZQznnLd
- SpaceControl https://t.co/S1NkJaeggR
Thanks for the kind invite @aycatakmaz🙏

[Project Aria @Meta @meta_aria]

What happens when you combine Meta's Project Aria with custom force-sensing grippers? 🤖👓

The new Hoi! dataset uses the egocentric perspective from Aria glasses to bridge the gap between what is seen, done, and felt; coupling egocentric vision and eye-tracking with real-world force sensing.

Great work from our partners at the @ETH_en Computer Vision and Geometry group! We’re looking forward to the presentations and discussions at #CVPR2026. 🥳

[International Conference on 3D Vision (3DV) @3DVconf]

Just as we say goodbye to Vancouver (YVR)🇨🇦🥹, it’s time to reveal our next destination! ✈️

From the Pacific coast to the Mediterranean sea...
We are thrilled to announce that #3DV2027 is heading to Thessaloniki, Greece (SKG)! 🇬🇷🥳

See you there in Mid-April 2027! 🌍

AnyUp has been accepted to ICLR 2026 as an oral presentation! ⭐️
I'm looking forward to presenting it in Rio. If you're interested, please come by my talk or poster. 🇧🇷

Super excited to introduce

✨ AnyUp: Universal Feature Upsampling 🔎

Upsample any feature - really any feature - with the same upsampler, no need for cumbersome retraining.
SOTA feature upsampling results while being feature-agnostic at inference time.
