Module intersects 

intersects(&a, &b) — see boost/geometry/algorithms/intersects.hpp.

Cartesian-only in v1. Default strategy is geometry_strategy::CartesianIntersects, which implements every pair in one canonical direction; the geometry_strategy::intersects::Reversed blanket lifts each pair to its swap.

Functions

intersects

true iff a and b share at least one point.

intersects_reversed

Reversed-direction entry point — used when only (B, A) has an explicit impl. Mirrors the Boost reverse_dispatch fallback in algorithms/detail/intersects/interface.hpp.
