At its core, GSAP doesn't do DOM manipulation. That's what the CSSPlugin does, so yes, you can use the easing functions for whatever you want. Every ease has a .getRatio() method, where you pass in a normalized value from 0 to 1.

 

var ratio = Power1.easeIn.getRatio(0.5);

 

Check out this post where I use different easings to plot points for sine waves.

 

 

If you need help normalizing a value, here's a little helper function. Just pass in the current, min, and max values.

 

// normalize will return a value between 0 and 1
function normalize(value, min, max) {
  return (value - min) / (max - min);
}
