As a feature extractor for point cloud #23

Hi, Is your pre-trained model suitable as a feature extractor for a point cloud shape, similar to PointNet? If it is suitable, which variable in the code should I output? I have observed that the shape of GPT_extractor is [batchsize, 64, 1024], which seems to be the features of the points group. Are there any features based on individual points? Thanks!
