collide 0.1.0

A collision detection package

The Group and Collide classes form a modular 2D collision detection system with clear separation of concerns. Group serves as a data container managing coordinate points and geometric shape creation. It supports rectangle, circle, triangle, and polygon generation through the create_shape() method, handling vertex storage, validation, and basic point operations (add/clear/get). For circular shapes, the num_vertices parameter controls polygon approximation precision (typically 8-32 vertices). Collide acts as a stateless utility class providing five core static methods: is_colliding_with() uses the Separating Axis Theorem to detect shape intersections; contains_point() implements ray-casting algorithm for point-in-polygon tests; get_bounding_box() computes axis-aligned bounding boxes; get_collision_points() identifies intersection coordinates between shapes; And contains_shape() verifies full containment of one shape within another. This architecture enables flexible integration into games, simulations, and interactive applications, balancing computational efficiency with geometric accuracy through robust floating-point tolerance handling and optimized projection calculations.
