This PR introduces a new public method,
screenPointToRay(Vector2f click2d)
, to theCamera
class. This method provides a highly efficient way to generate a pickingRay
in world coordinates from a given 2D screen coordinate.Motivation:
The ability to accurately and efficiently convert a 2D screen point (e.g., from a mouse click) into a 3D ray in world space is fundamental for various interactive features, such as:
