[Luckick]

Hi,

Is there any introduction about the format & meaning of .points and .octree format data?

Thank you!

Currently, one has to read the code to learn the detail about the .points and .octree format.
I will write more detailed explanation soon.

Would you mind to interpret the logic of some parts in Octree.cpp?

1. after get the node_keys, why do we need to build layers?
2. the node_keys is exact key that we get from volumetric data, why should we override node_key by keys_, where the last 3 digits of node_key are replaced.
3. What is the usage of children and addr?

Thank you for your help!

Sorry, it is hard for me to explain the implentation in a few words.
For the data structure, please follow the section 3 of our O-CNN paper, and some other useful reference can also be find in this section.
