If I have the following vector { x, y, z, w }, what role does w have in calculations such as dot product, cross product, vector addition / subtraction, etc. I'm just a bit confused as to whether it should be included in calculations or not.

    What do you mean? Are you talking about 3 dimensional *projective* space?2012-11-30

    Why does it make a difference if it's projective, or orthagonal, etc? I'm looking at this from a computer science point of view.2012-11-30
