| # PhysicsScenes |
|
|
| Anonymous submission for ICML 2026: **"PhysicsLM: Autoregressive Language Modeling of 2D Rigid Body Dynamics"** |
|
|
| ## Dataset Description |
|
|
| 900K 2D rigid-body physics scenes generated with Pymunk (Chipmunk2D), across |
| 30 scenario types in 6 physical categories. |
|
|
| ### Statistics |
|
|
| | Split | Scenes | Scenario types | Seeds | |
| |-------|--------|----------------|-------| |
| | Train | 900,000 | 24 (seen) | 1,000,000+ | |
| | Val | 100,020 | 30 (all) | 5,000,000+ | |
| | OOD (val) | 20,004 | 6 (held-out) | 5,000,000+ | |
|
|
| **Total size**: ~582 GB uncompressed. Due to size, this repository contains |
| metadata and a 1,000-scene sample. Full dataset available on request. |
|
|
| ### Format |
|
|
| Each scene is a JSONL file with 1 header line + 200 frame lines: |
| ``` |
| {"type": "header", "scenario": "billiards", "difficulty": 2, ...} |
| {"type": "frame", "frame": 0, "objects": [{"id": 0, "position": {"x": 400.0, "y": 300.0}, "velocity": {"x": -100.0, "y": 0.0}, ...}], ...} |
| ... |
| ``` |
|
|
| ### Scenario categories |
|
|
| - **Collision** (5 types): billiards, bowling, head_on, explosion, projectile |
| - **Stacking** (5 types): pyramid, tower, jenga, dominos, bridge |
| - **Ramp** (5 types): ramp_roll, ski_jump, marble_run, avalanche, plinko |
| - **Constraint** (5 types): pendulum, chain, seesaw, wrecking_ball, orbit |
| - **Minigame** (5 types): basketball, conveyor, pong, wind, breakout |
| - **Complex** (4 types, OOD only): angry_birds, hourglass, newtons_cradle, pinball |
