If it is not there create it, otherwise use the index. Now the first trick is to realize, that for every x,y,z you only need 3 possible vertices: down x, down y, down z. darling police station

Each edge is shared by up to 4 cubes. The total number of unique edges in each dim is equal to size+1 because the two end voxels don't share their edges.
