Detailed Description

Legacy geometric utilities — use point.H functions directly.

All functions in this file are deprecated. Prefer the canonical implementations in point.H: area_of_parallelogram(), orientation(), on_segment(), segments_intersect(), segment_intersection_point().

Deprecated:

Use point.H functions directly.
