ZipSplat: Fewer Gaussians, Better Splats
@veichta, Sunghwan Hong, @majti89, @mapo1
tl;dr: predict Gaussians directly in 3D from a compact set of scene tokens->decouple primitive placement from the 2D pixel grid

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.
