Bend Cast
Overview
Bend cast is the pointing version of the bubble cursor. By this it uses essentially the same algorithmic approach to distinguish between objects and the difference is how this is visualized for the user to control. The bend cast bends a vector originating from the control towards the closest object to that vector. This is essentially an enhancement of ray-casting as it is implemented as a bendy ray-cast.
