Worked on the godotengine/godot repository to enhance the reliability of 3D navigation by addressing a normalization bug in NavigationServer3D. Focused on correcting the normal vector calculations for the map_get_closest_point_normal function, ensuring that returned normals are properly normalized. This C++ fix improved the accuracy of point queries within 3D navigation systems, directly benefiting game development and simulation scenarios by providing more predictable navigation behavior. The work leveraged expertise in 3D navigation and game development, resulting in reduced debugging effort and more robust pathfinding under real-world conditions, ultimately supporting developers in building stable and accurate interactive 3D environments.
