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 number of values in one sample (the 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.
