I find there are 6 columns in a text file. I understand the first three columns are the coordinates of a point(XYZ), but what do the other three columns stand for?

For ModelNet, that is normal vector of point

For Point-Transformer, is it right to regards the last three columns as features of a point?

Alobal commented 2 years ago

Yes, it is always used as an additional feature
