Bent Pick Ray

A ray that bends towards the selected object so that several users can point at and move objects in a shared projection display.

How it works

The ray is drawn as a curve from the hand to the grabbed object, keeping a visible link even when the hand moves away from the straight line, which suits collaborative multi-user setups.
