Struct VerletCloth 

pub struct VerletCloth {
    pub points: Vec<VerletPoint>,
    pub cols: usize,
    pub rows: usize,
    pub rest_len: f32,
    pub stiffness: f32,
    pub iterations: usize,
    pub gravity: Vec3,
    pub damping: f32,
}

A 2D grid of Verlet points connected by distance constraints.

Suitable for cloth, net, and banner simulations. Grid is indexed row-major: index = row * cols + col.

Fields

points: Vec<VerletPoint>

cols: usize

rows: usize

rest_len: f32

stiffness: f32

iterations: usize

gravity: Vec3

damping: f32

Implementations

impl VerletCloth

pub fn new(origin: Vec3, cols: usize, rows: usize, spacing: f32) -> Self

Create a flat cloth grid starting at origin, spreading along +X, +Y.

pub fn tick(&mut self, dt: f32)

Simulate one step.

pub fn apply_wind_gust(&mut self, center: Vec3, strength: f32, radius: f32)

Apply a spherical wind gust — pushes cloth points near center outward.

pub fn tear(&mut self, center: Vec3, radius: f32)

Tear the cloth at a point — unpin nearby points to simulate a hole.

pub fn point(&self, row: usize, col: usize) -> Vec3

pub fn pin(&mut self, row: usize, col: usize)

pub fn unpin(&mut self, row: usize, col: usize)
