Hi everybody,
I'd like to find a way of using the velocity of a null in global space
(via the global kine PPG) to drive some distortion of UVs in another
object's material. Now I have pretty my everything setup, but I'd just
like to know how one goes about turning these linear/anguar/x/y/z
velocities into a kind of general 'speed' to drive the effect. i.e.
when object moves fast, distortion increases, when it stops, distortion
stops.... ideally with a nice lag but that I can probably live without
this time.
Should I just take the average of the absolute xyz velocities?
I'll be the first to admit I need get my head in the maths books, and
I'm sure the answer will be painfully embarassing, but what the hey,
bring it on!
Thanks in advance,
DAN
