Function spring

Produces values according to rough spring physics.

import { continuously } from "https://unpkg.com/ixfx/dist/flow.js"
import { spring } from "https://unpkg.com/ixfx/dist/modulation.js"

const s = spring();

continuously(() => {
 const result = s.next();
 if (result.done) return false; // Exit loop
 const value = result.value;
 // Value is mostly within 0..1 range but will exceed these limits
}, 10).start();
Copy

Parameters to the spring can be provided.

import { spring } from "https://unpkg.com/ixfx/dist/modulation.js"
const s = spring({
 mass: 5,
 damping: 10
 stiffness: 100
});
Copy

If you don't want to use a generator: springValue.

Note that the generated value can exceed 0..1 range. This is by design, since a spring can 'overshoot'. See Data.Normalise for functions to normalise.
