The training-free pipeline combines pretrained models for instance discovery, segmentation, object reconstruction, and pose recovery. A render-match-optimize loop estimates scale and motion, while physics-grounded assembly enforces contact and support. Direct vertex deformation represents both rigid and non-rigid behavior without requiring skeleton rigging.
OVOW is useful for research on video-to-simulation conversion and structured world-model datasets. Outputs include watertight instances and URDF-compatible scene assembly. Although its own code is MIT-licensed, bundled dependencies impose additional restrictions, so the assembled release is intended for noncommercial research rather than unrestricted commercial deployment.
