STANCE Scenes (Composite & Synthetic)

Snapshot: 95k scenes total — 75,000 composite + 20,000 synthetic/simple.
Built with Kubric for short clips of rigid-body interactions.

Synthetic/simple: minimal scenes with one or more rigid objects; randomized shape (ball / a few primitives), mass, initial linear velocity, and pose. Lighting uses three area lights plus a sun with randomized intensity/temperature.
Composite: replaces primitives with GSO assets; backgrounds sampled from ~5,000 environment maps; randomized object selection/placement/pose to induce diverse contacts and occlusions.
Camera intrinsics/extrinsics and renderer settings are consistent within each scene; material, friction, restitution, and object counts are sampled within bounded ranges.
