Disoriented Normals

[basit-7]

Hi, I have been experimenting with the code and trying to reproduce the results shown in the paper. Till now, I have not been able to produce the results shown specifically in Fig. 3 in the paper. The reason is that the normals are all facing in one direction and so Poisson reconstruction does not produce the correct mesh.

I have also noticed that the sparse point clouds in test data also have this same issue.

The image below shows a point cloud upsampled with PUGeo-Net. The direction of the normals is not correct. I have evaluated it on several different point cloud but the same problem persists. What could be the issue?
