CausalSpatial: A Benchmark for Object-Centric Causal Spatial Reasoning

Wenxin Ma, Chenlong Wang, Ruisheng Yuan +6

Humans can look at a static scene and instantly predict what happens next -- will moving this object cause a collision? We call this ability Causal Spatial Reasoning. However, curr…

Tinker: Diffusion's Gift to 3D--Multi-View Consistent Editing From Sparse Inputs without Per-Scene Optimization

Canyu Zhao, Xiaoman Li, Tianjian Feng +3

We introduce Tinker, a versatile framework for high-fidelity 3D editing that operates in both one-shot and few-shot regimes without any per-scene finetuning. Unlike prior technique…
