During March 2025, Avej worked on the LimeShot/cringe-vector repository, developing a rotation-aware point-in-polygon algorithm for the IsBelongsShape function. By replacing a temporary bounding box check with a ray-casting approach, Avej addressed the challenge of accurately determining point containment in rotated polygons and evaluating proximity to polygon edges within a configurable radius. This solution, implemented in C# and leveraging skills in algorithm implementation, geometry, and vector math, improved the precision of spatial queries while maintaining real-time performance. The work demonstrated a thoughtful approach to geometric accuracy, particularly for UI and geometry scenarios requiring reliable and efficient containment checks.
