LiSu provides synthetic LiDAR point clouds, each annotated with surface normal vectors.
This dataset is generated using [CARLA](https://github.com/carla-simulator/carla) simulator, ensuring diverse environmental conditions for robust training and evaluation.
Below is an example from LiSu, where surface normals are linearly mapped to the RGB color space for intuitive visualization:
