Ok I’ve updated the script controllers to give a smooth curve, and it should be much nicer to use.Balance now contols the balance of a gamma curve.
The left Eye script looks like…
dependsOn $SliderDilate $sliderbalance
x = 1 – $SliderDilate.value
b = $sliderbalance.value
(bxx + (1-b)*x)*100
The Right Eye script is the same except
b = -$sliderbalance.value
Have a go…
Interesting, this is a gamma function you say. Hmmm ill have to look into this. Is this similair to exponential ramp: n^2.618?
eek
To be precise its a 2nd order approximation of a gamma curve. A friend of mine did the math to derive the approximation so I cant claim credit for that.
In my code the gamma value is (1+balance)/2.
Its loses accuracy when compared to a real gamma curve when balance is close to +1 or 1. But mostly we want something that feels right and runs fast, so thats usually fine.
I’m not familiar with an exponential ramp: n^2.618. Could you give me an example eek?
Hey Ken it looks much like a bezier curve what you have there. Interesting way of dealing with it. Thanks for sharing.
