OVOW turns monocular video into physics-ready 4D scenes
Researchers just open-sourced OVOW, a training-free system that turns a single video into simulation-ready 4D mesh scenes with separated objects. By chaining models like Qwen3-VL and SAM 3, it reconstructs motions and deformations directly for physics simulators. It is available for non-commercial research and recommends at least 40GB of VRAM.
