Question on the number of points #82

Hello author,

I have a question about the number of points in a single-point cloud. Seemingly, it is difficult to input the entire points to the model. Then, can you tell me the number you fixed for subsampling a single-point cloud for the nuScenes and Semantic-KITTI??

Thanks

We didn't crop point cloud for nuScenes and Semantic-KITTI, but you can refer to this: https://github.com/Pointcept/Pointcept/blob/main/configs/nuscenes/semseg-pt-v3m1-0-base.py#L117
