説明

レイにより衝突された表面の法線ベクトル

The normal vector of a surface is the vector that points outward perpendicularly at a given point on that surface. This vector can be useful in raycasting as a way to determine reflections or ricochets from projectiles or to align a character so that it stands upright on the surface.

Note: If a hit occurs starting inside a collider then the collision normal will be simply the opposite direction of the line/ray query.
