Re: Connectivity in Connected Components

Thanks for the reply, Daniel. I still have two questions left. It would be kind of you to answer them as well. 1. How are the neighbors of each octant determined? I found this paper by Hanan Samet (1989) which describes some methods apperently still applied today. http://www.cs.umd.edu/~hjs/pubs/Sam...

Re: Connectivity in Connected Components

Thanks for the quick reply, Daniel. Does a detailed description for the Connected Components algorithm exist besides the info on this site and the manual? From what I understood it works like the 2D version, only that we define adjacency/connectivity based on a shared area, edge or corner. The depth...

Connectivity in Connected Components

Greetings CloudCompare forum,

I'm currently describing the CC-algorithm for a thesis and would like to know which kind of connectivity between the octants is used, ie. is it 6, 18 or 26 connectivity?

Many thanks,
kind regards
