- [Jan 17, 2026] Data Release
Wanderland is a comprehensive framework that consists of many different components. Each component is relatively independent so please refer to the README.md file in each subfolder for more details. Note that all components use uv for dependency management. Please install uv first if you haven't done so.

- To download data from Hugging Face, check data_processing
- To benchmark 3D reconstruction methods, check 3d_recon_benchmark
- To evaluate navigation performance, check navigation [TODO]
- To reproduce our reconstruction pipeline, check reconstruction
Each component have its own virtual environment. Remember to deactivate and reactivate the venv when switching between different components.
