How to pretrain using PointNext backbone as encoder?

[Daniellli]

hi,
I am curious of how to pertrain with other backbone such as PointNext. And, as shown in your paper, you experiment with PointNext and show a promising results. Could you release the PointNext pretrain code.

appreciate for your help.

We will public the new backbone model later. If you have read and understand our paper, you should find it is very easy to replace the encoder backbone. I would appreciate it a lot if you can also try to implement by yourself.
