Given a 3D space and a light source, I use ray casting to determine the shadows generated in the scene. If I'm to store the shadow data (boundary of the shadow, object which cast the shadow, etc.) what is an efficient way to go about it?
Its basically for an application where I want to be able to move the shadow around manually to see the change in the 3d objects position. Say I apply a force to the shadow of a ball, I can actually see the ball move and also the change in the shadow. So I need to be able to set up colliders for the shadow and hence need a way to be able to store the boundary of the shadow and information about the object that cast it to carry out the actions.
