# LychSim Scenes Dataset
[Project Page](https://lychsim.github.io/) | [Paper](https://huggingface.co/papers/2605.12449) | [GitHub](https://github.com/wufeim/LychSim)
LychSim is a highly controllable and interactive simulation framework built upon Unreal Engine 5 for vision research. This dataset contains scene-level procedural rules for the simulator.
## Description
For each scene, we capture structural priors — navigable floor spaces, road areas, pedestrian walks, and dynamic vehicle / pedestrian trajectories — as structured records keyed to the underlying placed actors. These spatial priors guide the procedural generation process, ensuring that newly synthesized layouts remain faithful to the original scene semantics.
## Sample Usage
You can load the dataset using the Hugging Face `datasets` library:
```python
from datasets import load_dataset
scenes = load_dataset("wufeim/lychsim_scenes")
```
