Hi,
Great work with heat diffusion for distance field. Two questions:
I first run the 2D cases, same as reported in paper, the interior region is non-expected. There is no uniform distance propagation in very interior region as GT shows. I wonder why this?
Second, as mentioned in paper, no pcd normals are used during training. How the interior and exterior can be distingulished for SDF learning?
Thanks in advance for your reply.
