For the longest time I was content to think that 'w' was just added to vector processors to fill in the extra value in the set of four to match the four values neccessary for color. From all this I've gathered that 'w' is neccessary to make the perspective matrix work. So if I were to carry this logic further I would surmise that 'w' is scaled down by the projection matrix math for vertices that are further back and scaled up for objects that are closer to give the illusion of depth. Thus we have perspective on the matter!

There is far too much arrogance and out right abuse by site moderators, they are teaching other people to behave this way. The posts I've made will all be shorty removed and replaced with this notice. Game development is not the only thing being taught here, bad behavior is being taught as well.
