Games and AI - alternative path finding
Additional learning: in games engines like Unity where ray casting can be used, the normal vector to the collision (ray cast hit variable) can be used to navigate around objects; while traversing to a target destination. This results in a simple steering mechanism, steering (allowing object to be avoided and some autonomy on the navigation of a path) and navigation being separate elements of navigation AI; but in general lower necessary resource needs, and can be more easily be draw out in games - such as Assasin Creed allowing players to see the path line and gui models to points on the path - if one desires to do this.
