Struct Spring 

Source 
pub struct Spring {
    pub particle_a: usize,
    pub particle_b: usize,
    pub rest_length: f32,
    pub stiffness: f32,
    pub damping: f32,
    pub enabled: bool,
}
Expand description

A spring constraint between two particles.

Springs create restoring forces based on distance deviation from rest length.

Fields§

§particle_a: usize

Index of first particle

§particle_b: usize

Index of second particle

§rest_length: f32

Rest length of the spring

§stiffness: f32

Spring stiffness (higher = stiffer)

§damping: f32

Damping coefficient (higher = more damping)

§enabled: bool

Whether this spring is enabled

Implementations§

Source§

impl Spring

Source

pub fn new( particle_a: usize, particle_b: usize, rest_length: f32, stiffness: f32, damping: f32, ) -> Self

Create a new spring between two particles.

§Arguments
  • particle_a - Index of first particle
  • particle_b - Index of second particle
  • rest_length - Natural length of the spring
  • stiffness - Spring constant (force per unit extension)
  • damping - Damping coefficient (velocity damping)
Source

pub fn compute_force( &self, pos_a: Vector3<f32>, vel_a: Vector3<f32>, pos_b: Vector3<f32>, vel_b: Vector3<f32>, ) -> Vector3<f32>

Compute spring force on particle A (force on B is negated).
