SpringSim constructor

SpringSim({ required double from, required double to, double mass = 1.0, double stiffness = 100.0, double damping = 10.0, double initialVelocity = 0.0, })

Implementation

SpringSim({
  required this.from,
  required this.to,
  this.mass = 1.0,
  this.stiffness = 100.0,
  this.damping = 10.0,
  this.initialVelocity = 0.0,
}) {
  _omega0 = math.sqrt(stiffness / mass);
  _zeta = damping / (2.0 * math.sqrt(stiffness * mass));
  final discriminant = 1.0 - _zeta * _zeta;
  _omegaD = _omega0 * math.sqrt(discriminant.abs());
}
