PhysJEPA motion caches Derived caches for two-stage physics-consistent video generation on Physion. stage1_flow_targets/ -- analytic ground-truth optical flow reconstructed from the simulator's mesh vertices, quaternion poses and camera matrices by z-buffer rasterisation (Drape uses flex particles + Delaunay). Not RAFT. Each entry holds flow (7,2,160,160) in pixels, forward and cumulative from the first frame at 0.2s..1.4s, plus visibility, object_mask, future_mask, instance_id… See the full description on the dataset page: https://huggingface.co/datasets/yrlyrl/physjepa-motion-caches.
