BoundCircle

The BoundCircle type defines a bounding circle for 2D space, providing efficient spatial containment, expansion, and intersection logic. It supports initialization from points, bounding rectangles, and other circles, and offers utilities for validation, distance computation, radius growth, and spatial queries. The implementation prioritizes performance, precision, and flexibility with support for custom vector types.
