    clarification for Atlanta420 on tutorials

    Hey, you IMed me and I was away, and my away message doesn't appear to have responded to you, so here's my answer.

    Atlanta420: hi i have a ?
    Atlanta420: im looking at ur tutorial for roating a pt
    Atlanta420: ??
    Atlanta420: i dont see how those forumulas take the initial pt (location) into acct say im at (1,0) i know a 90 degree rotation moves it to (0,1) but using ur formulas does not take the position into account so how do u move the pt?
    1) please make an effort to type intelligibly. I know that makes me sound like a jerk, but I don't "want 2 r3ad nonsense"

    Actually the rotations don't take the position into account, they only rotate the normalized view vector that is at the origin. To calculate the point you are looking at to be used in a graphics library you have to do

    Position + View
