    pub friction: f64,
    pub restitution: f64,
}

Physical material properties.

Fields

name: String

Material name

density: f64

Density in kg/m^3

friction: f64

Coefficient of friction (0..1)

restitution: f64

Coefficient of restitution (bounciness, 0..1)

Implementations

impl Material

pub fn new( name: impl Into<String>, density: f64, friction: f64, restitution: f64, ) -> Self

Create a new material with the given properties.

impl Material

pub fn impedance(&self, speed_of_sound: f64) -> f64

Compute the impedance (density * speed_of_sound).

speed_of_sound - Speed of sound in the material (m/s).

pub fn is_heavier_than(&self, other: &Material) -> bool

Check whether this material is heavier than another.

pub fn is_bouncier_than(&self, other: &Material) -> bool

Check whether this material is bouncier than another.

pub fn combine_average(&self, other: &Material) -> Material

Combine this material with another using average rules.

pub fn weight(&self, volume: f64, gravity: f64) -> f64

Compute the weight of a given volume of this material (density * volume * g).

pub fn mass_from_volume(&self, volume: f64) -> f64

Compute the mass of a given volume of this material.
