For each scene we specified physical parameters (gravity, materials, initial velocities, friction, restitution), ran deterministic simulation, and rendered video frames at 24 fps along with per-frame instance segmentation, depth, mask, velocity, and density buffers. Ground-truth labels are computed directly from physics-engine state.",
