Implementation

@override
List? interpolate(int i1, num t0, num t, num t1) {
  final result = resultBuffer,
      values = sampleValues,
      stride = valueSize,
      offset1 = i1 * stride,
      offset0 = offset1 - stride,
      weight1 = (t - t0) / (t1 - t0),
      weight0 = 1 - weight1;

  for (int i = 0; i != stride; ++i) {
    result?[i] = values[offset0 + i] * weight0 + values[offset1 + i] * weight1;
  }

  return result;
