Abstract base class of interpolants over parametric samples.

The parameter domain is one dimensional, typically the time or a path along a curve defined by the data. The sample values can have any dimensionality and derived classes may apply special interpretations to the data.

This class provides the interval seek in a Template Method, deferring the actual interpolation to derived classes. Time complexity is O(1) for linear access crossing at most two points and O(log N) for random access, where N is the number of positions.


Interpolant(parameterPositions : Array | TypedArray, sampleValues : Array | TypedArray, sampleSize : Integer, resultBuffer : Array | TypedArray)

parameterPositions — array of positions.
sampleValues — array of samples.
sampleSize — number of samples.
resultBuffer — buffer to store the interpolation results.

This constructor is designed to be called via subclass, not directly.


.parameterPositions : Array

Array of positions.

.resultBuffer : Array

Array to store interpolation results.

.sampleValues : Array

Array of samples.

.settings : Object

Optional, subclass-specific settings structure.

.valueSize : Integer

Number of samples.


.evaluate(t : Float) → Array

Evaluate the interpolant at position t.
