the orientation of normal is very strange!

Hey guys, I appreciate the awesome work!
when I ran the test with the image from my D405 depth camera, I got this result.
it seems right.

but, when I read the normal from this image, and put it in my point cloud. the normal is not along with the surface. but the orientation of light.

Hi,

FYI, we use the right-handed coordinate system with (X, Y, Z) = (right, down, front). An important thing to note is that both the ground truth normals and our prediction are the outward normals. For example, in the case of a fronto-parallel wall facing the camera, the normals would be (0, 0, 1), not (0, 0, -1). If you instead need to use the inward normals, please do normals = -normals.

Let me know if this fixes the problem!

very appreciate for your reply。
I have solved it! the result is awe-inspiring！
