Hi,

I was going through the code as in the file 'frustum_pointnets_v1_sunrgbd.py'. In line 38 it says the input has dimensions of B N 4. What is B and N exactly? And what does that input size convey exactly? Help will be really appreciated. Thanks a lot in advance.

Kind Regards Pranjal Biswas

On reading more carefully I see that B: Batch Size, N: NUM_POINT. What exactly is NUM_POINT? And why the 4 in input dimension(B N 4)?
