Vector Addition Demo

Vector Addition Demo is exactly what you'd think.  It's a tool for demonstrating the addition of two vectors.  The two vectors and their sum are shown both graphically and analytically, presenting their x- and y-components.  The three vectors are defined by the position two objects relative to the coordinate system origin.  The magenta object is a child of the cyan object, so as the cyan object is moved, the magenta object will move as well, maintaining the same relative position.

The three vectors are defined as follows:

a = absolute position of the parent object

b = relative position of the child object to the parent

c = absolute position of the child object

This tool can also be used to illustrate the basic relationship between world and local coordinates in parent/child object relationships.
