The vector between the origin (0,0,0, 1) and the point (x, y, z, 1) is the difference v
Chapter 8, Problem 16(choose chapter or problem)
The vector between the origin (0,0,0, 1) and the point (x, y, z, 1) is the difference v = . In homogeneous coordinates, vectors end in . So we add a __ to a point, not a point to a point.
