QuaternionLinearInterpolant

class QuaternionLinearInterpolant(parameterPositions: DoubleArray, sampleValues: DoubleArray, sampleSize: Int, resultBuffer: DoubleArray = DoubleArray(sampleSize)) : Interpolant

Spherical linear unit quaternion interpolant.

parameterPositions

The parameter positions holding the interpolation factors.

sampleValues

The sample values.

sampleSize

The sample size (a.k.a. the value size / stride).

resultBuffer

The result buffer; defaults to a fresh DoubleArray(sampleSize).

Constructors

constructor(parameterPositions: DoubleArray, sampleValues: DoubleArray, sampleSize: Int, resultBuffer: DoubleArray = DoubleArray(sampleSize))

The default settings object. Overridden by CubicInterpolant.

The parameter positions.

The result buffer. Reused across calls; overwritten by every evaluate.

The sample values.

The interpolation settings. null until assigned; getSettings_ then falls back to DefaultSettings_.

The value size (stride).

Copies a sample value to the result buffer.

Evaluates the interpolant at position t.

Returns the interpolation settings.
