Hello, may I ask which version of the "shapenetcore" is used for the dataset in your paper? I found v1 and v2 on the official website. Looking forward to your reply and wishing you a happy life!
Actually, I have used various datasets including my own dataset, and I have got similar results like a result of clustering point-clouds. I don't know why.
the first one is plane, and the second one is a can.
