hello again... i was going over vectors and vector math and i was wondering, how can a single point, a vector, have a direction? -PmanC

Imagine that you''re standing at the origin and looking at your point. The way you''re looking is the point vector''s direction.

another way of thinking of point vectors is:

+1, +2, -3

i.e. wherever you are, the direction of the point vector is +1 in the x-direction, +2 in the y-direction and -3 in the z-direction.

vectors are always in reference to some other point. think of it as a floating directional arrow. just add the values of the vector to whatever point you want the base of the arrow to be and you'll get the point that the arrow is "pointing at". the line from the base to the "pointing at" point is the direction of the vector.

oh... ok, so really the direction is the line created by the origin and the vector. -PmanC
