Thank you for open-sourcing the code !

I couldn't find the visualization code however. Could you share that? I couldn't completely understand how you used PCA to project it onto the point clouds, it would be great if you could shed some light into the process.

Thank you!

Yes, this visualization effect is great. Could you please share this code with us. Thank you very much.

I don't think I have the visualization code anymore, it was a mess. However, it was loosely based on this: https://github.com/jiachens/ModelNet40-C/tree/master/visualize

For PCA, we computed it over all the points in a single point cloud, then mapped the top three components to the RGB channels.
