Struct ClothEdge

Source

pub struct ClothEdge {
    pub v0: usize,
    pub v1: usize,
    pub rest_length: f64,
    pub stiffness: f64,
    pub damping: f64,
}

Expand description

A structural spring edge connecting two cloth vertices.

Fields§

§v0: usize

Index of the first vertex.

§v1: usize

Index of the second vertex.

§rest_length: f64

Rest length of the spring (m).

§stiffness: f64

Spring stiffness (N/m).

§damping: f64

Damping coefficient (N·s/m).

Implementations§

Source §

impl ClothEdge

Source

pub fn new( v0: usize, v1: usize, rest_length: f64, stiffness: f64, damping: f64, ) -> Self

Create a new edge.

Source

pub fn spring_force(&self, verts: &[ClothVertex]) -> [f64; 3]

Compute the spring force acting on vertex v0 (force on v1 is negated).

Includes both Hooke’s law and linear damping.
