Can we train the 3d model one sample a time but one patch a time?

Hey, @jayliu0313
Can we train the 3d model one sample a time but one patch a time?
I think the pointnet and the NIF in Shape-Guided is designed for a patch, we may not cut the pointcloud into 3415003(which means patchpointnumxyz), we can concate all the sample together in the patch dim, if we have 200 sample, the result will be 682005003, then we can the increase the batchsize to train the 3d model, may be set the batchsize as 32.
