I see. Ok, well - clamp seems to only give either upper value or lower value depending on how close the variable is to either.
lerp - well, still trying to wrap my head around lerp (and I suspect is probably what I need to use - still tinkering with it)
but essentially, this is what I am trying to figure out:
I have a character falling and falling. Velocity of the fall i have set to an upperbound of 1200. I have particles that trail behind (speed lines) but I want the opacity to increase as the rate of descent increases. Since opacity is between 0 and 1 - i'm looking for a way to convert my numbers (velocity, upperbound) to a value between zero and 1.
Newt - thanks for the suggestion, but I have other uses and would like a more normalized number.
my brain asplodes when looking at things like this: stn.spotfire.com/spotfire_client_help/norm/norm_scale_between_0_and_1.htm
