float phaser(float pct, float phase, float e) {
return clamp( (phase-1.+pct*(1.+e))/e, 0., 1.);
}
Phaser is a parameterized easing function for phase-staggered animations. The arguments:
- pct : [0,1]
- phase : [0,1]
- e (edge) : > 0
These are the characteristics of the function:
- When pct is 0, phaser returns 0, regardless of the other variables.
- When pct is 1, phaser returns 1, regardless of the other variables.
- All else equal, a larger phase causes phaser to return 1 sooner.
- All else equal, a larger edge causes differences in phase to matter less.
- All else equal, a smaller edge causes differences in phase to matter more. (Corollary to previous)
