## Variable Documentation

## ◆ BEZIERSPLINE3

const byte BEZIERSPLINE3 =4

Perform a cubic Bezier spline interpolation.

That is, when interpolating at position t, take the three closest data points v0, v1, and v2, fit a cubic Bezier spline through them, and take the interpolated value from this cubic curve.

## ◆ BEZIERSPLINE4

const byte BEZIERSPLINE4 =5

Perform a quadric Bezier spline interpolation.

That is, when interpolating at position t, take the four closest data points v0, v1, v2, and v3, fit a quadric Bezier spline through them, and take the interpolated value from this quadric curve.

## ◆ CUBIC

const byte CUBIC =3

Perform a cubic interpolation.

That is, when interpolating at position t, take the four closest data points v0, v1, v2, and v3, fit a cubic curve through them, and take the interpolated value from this cubic curve.

## ◆ LINEAR

const byte LINEAR =2

Perform a linear interpolation.

That is, when interpolating at position t between two values v0 and v1, positioned at t0 and t1, take the sum of v0 weighted with (t-t0) and v1 weighted with (t1-t).

## ◆ NEAREST_NEIGHBOR

const byte NEAREST_NEIGHBOR =1

Perform a nearest neighbor interpolation.

That is, when interpolating between two values v0 and v1, positioned at t0 and t1, take the one which has the closest t coordinate.
