Range and segment trees allow to perform window queries on point sets, and to enumerate all ranges enclosing a query point. The provided data structures are static and they are optimized for fast queries.

This chapter presents the CGAL range tree and segment tree data structures.

The range tree is theoretically superior to the \( Kd\)-tree, but the latter often seems to perform better. However, the range tree as implemented in CGAL is more flexible than the \( Kd\)-tree implementation, in that it enables to layer together range trees and segment trees in the same data structure.
