lerp method

double lerp(double t)

Returns the value this variable has at the given animation clock value.

The default implementation of this method uses the +, -, and * operators on T. The begin and end properties must therefore be non-null by the time this method is called.

In general, however, it is possible for this to return null, especially when t=0.0 and begin is null, or t=1.0 and end is null.

Implementation

double lerp(double t) {
  if (t < 1.0 / 3) {
    return lerpDouble(1.0, 0.0, t * 3) ?? 0.0;
  } else {
    return lerpDouble(0.0, 1.0, (t - 1.0 / 3) * 1.5) ?? 0.0;
  }
}
