query_pairs(r, p=2.0, eps=0)¶
Find all pairs of points within a distance.
r : positive float
The maximum distance.
p : float, optional
Which Minkowski norm to use. p has to meet the condition
1 <= p <= infinity.
eps : float, optional
Approximate search. Branches of the tree are not explored if their nearest points are further than
r/(1+eps), and branches are added in bulk if their furthest points are nearer than
r * (1+eps). eps has to be non-negative.
results : set
Set of pairs
i < j, for which the corresponding positions are close.
