Struct SpringSolver 

pub struct SpringSolver { /* private fields */ }

Solves the motion of a damped spring: maps a time to the position of a spring that is released at 0 and settles at 1.

Implementations

impl SpringSolver

pub fn from_period( period_seconds: f64, zeta: f64, initial_velocity: f64, ) -> Self

Creates a solver from the period of the undamped oscillation in seconds, the damping ratio and the initial velocity.

pub fn new(m: f64, k: f64, c: f64, initial_velocity: f64) -> Self

Creates a solver from the mass m, the stiffness k, the damping coefficient c and the initial velocity.

pub fn from_natural_frequency(wn: f64, zeta: f64, initial_velocity: f64) -> Self

Creates a solver from the natural frequency, the damping ratio and the initial velocity.

pub fn solve(&self, t: f64) -> f64

The position of the spring at time t.
