Struct SpringDesc 

pub struct SpringDesc {
    pub mass: f64,
    pub stiffness: f64,
    pub damping_ratio: f64,
}

Physical parameters of a damped spring (a mass on a spring with a damper).

damping_ratio is the dimensionless ζ: < 1 under-damped (overshoots and oscillates), == 1 critically damped (fastest non-overshooting settle), > 1 over-damped (slow, no overshoot). M3’s standard spring presets (which live in frust-theme, not here) are expressed in these terms.

Fields

mass: f64

Mass of the moving body (> 0).

stiffness: f64

Spring stiffness k (> 0); higher is snappier.

damping_ratio: f64

Damping ratio ζ (> 0); see the type docs.
