Excuse me, where is the path to save the point cloud file after adding snowflake simulation noise? Thank you！ #20

Hi (I guess Pengfei from the email), you could write your own export function to save the point cloud (pc) in your desired format and call that function at the end of show_pointcloud, e.g. here: https://github.com/SysCV/LiDAR_snow_sim/blob/main/pointcloud_viewer.py#L3017 Greets, Martin

Thanks for your time! In the process of saving the data, I just saved the XYZI 4D information of the point cloud data, which were saved as a bin file. The size of the saved KITTI single frame data is 16k, which is much smaller than the 1.*M of the original KITTI dataset, I would like to know , will this affect the subsequent training?

Hi， may I know how do you get the simulation of snow+wet and which .py should I run to achieve? Thank you very much!
