Ground truth normal generation #5

Closed ziruiw-dev closed 4 years ago

Hi @paulguerrero,

Thanks for releasing your code. I was wondering if I can ask how are the ground truth normals generated in the dataset? Is it using PCA and KNN?

Best, Zirui

Hi Zirui, all point clouds were sampled from dense ground truth meshes, and the ground truth normals are obtained from these meshes (the normal of the face containing a point).

Thanks a lot for the prompt response and answer. Best, Zirui
