CubicInterpolant

Fast and simple cubic spline interpolant.

It was derived from a Hermitian construction setting the first derivative at each sample position to the linear slope between neighboring positions over their parameter interval.

Constructor

new CubicInterpolant( parameterPositions : TypedArray, sampleValues : TypedArray, sampleSize : number, resultBuffer : TypedArray )

Constructs a new cubic interpolant.

parameterPositions | The parameter positions hold the interpolation factors.
---|---
sampleValues | The sample values.
sampleSize | The sample size
resultBuffer | The result buffer.
