Thanks for your brilliant open-source work. And I have a question about the GRNet. For the input partial point cloud, you multiply by 0.5 in your code. May I ask why you chose to do this? Will this greatly influence the results?
Looking forward to your reply! :-)

Point clouds in PCN are in [-0.5, 0.5] while point clouds in ShapeNet-55/34 lay in [-1, 1].
if we do not multiply 0.5 on coordinates, gridding operation will raise a error.

Ok， thanks for your reply!!!
