The CityTopia Dataset
from CityDreamer4D: Compositional Generative Model of Unbounded 4D Cities
Haozhe Xie, Zhaoxi Chen, Fangzhou Hong, Ziwei Liu from S-Lab, Nanyang Technological University
TL; DR: CityTopia is the largest synthetic dataset for 3D cities with annotations, offering high-fidelity scenes generated using 3D assets from the Unreal Engine 5 CitySample project.
More download options, including Google Drive and Baidu Drive, are available here.
Features
- High Fidelity: Created using cutting-edge Unreal Engine 5 assets for realistic urban scenes.
- Diverse Annotations: Includes semantic and instance annotations at 1080p resolution.
- Versatile Renders: Contains day and night scenes in multiple resolutions.
- Customizability: Provides source files for city generation via Houdini, enabling custom dataset creation.

Recommendations
- Use
CityTopia-Annotations-1080p.zipfor all semantic and instance labeling needs. - For lower resolution, opt for
CityTopia-RGB-Day-540p.zipandCityTopia-RGB-Night-540p.zip. - Select 1080p files (
CityTopia-RGB-Day-1080p.zip,CityTopia-RGB-Night-1080p.zip) only if high-resolution images are necessary. - Use
CityTopia-HoudiniFiles.zipif custom 3D cities are required for advanced experiments.
