Returns a function that interpolates from A to B.
It steps through the interpolation with each call to the returned function.
This means that the incrementAmount will hinge on the rate
at which the function is called. Alternatively, consider @ixfx/numbers.interpolatorInterval
which steps on the basis of clock time.
// Interpolate from 0..1 by 0.01 constv = interpolatorStepped(0.01, 100, 200); v(); // Each call returns a value closer to target // Eg: 100, 110, 120, 130 ...
Under the hood, it calls interpolate with an amount that
increases by incrementAmount each time.
When calling v() to step the interpolator, you can also pass
in new B and A values. Note that the order is swapped: the B (target) is provided first, and
then optionally A.
constv = interpolatorStepped(0.1, 100, 200); // Interpolate 100->200 v(300, 200); // Retarget to 200->300 and return result v(150); // Retarget 200->150 and return result
This allows you to maintain the current interpolation progress.
