scaling back to linear ?
Hello maxers,
does anybody know if there's a way to "invert" an exp scaling so that it goes back to linear like in the following example.
thanks

If the first lin->exp scaling is in the form x^y and you know the value used for y then you can reverse it by using x^(1/y) e.g. x^2 -> x^0.5
thanks, I'll look into that, missed that thread...
Any idea tho on how the exp base value used as the fifth arg in scale would translate into an expr using pow ? my maths are far away ;-)
ph
I checked your patch earlier and used my suggestion of taking the reciprocal of the exponent as the new exponent in a reverse conversion, and I got a straight line....
So I think if you were using [expr pow] it translates to how the curve would behave if [scale] were first converting it's input to 0->1, raising the result to a power, then scaling/offsetting as required by [scale]'s output behaviour. If that makes sense....
