Points & Vectors

Points - (X,Y,Z) locations - can be treated as vectors

Technically, they're different. But when programming, it's convenient to use a vector class for points.

e.g., to get a vector that points from one position to another (from pos1 to pos2):

	pos1 = Vector((10, 10, 10))
	pos2 = Vector((-5, 0, 17))

	delta = pos2 - pos1
