One last question,is it needed that at least 1 vectorin the dot product is normalized? If you look above in the sourcecode you will see that in every dot product there is one simple vector and a normalized one.

Madhed seriously?! Please don't make it more complicated because my head will explode.I don't have a good background with math at all:) Thanks for all the help,I will save this page as html to view it anytime I forget something about this!
