The benchmark is six path-traced scenes with large motion: fluids, foliage, night lighting, particles, and caustics. Each scene is 300 frames (10 s at 30 fps) at 1600×900. Cameras are arranged in rigs of several circular arrays. Evaluation holds out 1–4 cameras per scene; the remaining cameras are the training views.

Five scenes are in this repo as Parquet files. The underwater scene (1_4_underwater) is coming soon.
