Struct SpringNetwork 

pub struct SpringNetwork {
    pub positions: Vec<Vec3>,
    pub velocities: Vec<Vec3>,
    pub masses: Vec<f32>,
    pub edges: Vec<(usize, usize, f32, f32)>,
    pub gravity: Vec3,
    pub damping: f32,
    pub iterations: usize,
}

A general graph of nodes connected by spring edges.

Each node is a mass-point; edges are distance constraints. Useful for soft body shapes, molecules, and amorphous entities.

Fields

positions: Vec<Vec3>

velocities: Vec<Vec3>

masses: Vec<f32>

edges: Vec<(usize, usize, f32, f32)>

Edges: (node_a, node_b, rest_length, stiffness).

gravity: Vec3

damping: f32

iterations: usize

Implementations

impl SpringNetwork

pub fn new() -> Self

pub fn add_node(&mut self, pos: Vec3, mass: f32) -> usize

pub fn add_edge(&mut self, a: usize, b: usize, stiffness: f32)

Add an edge between two nodes. Automatically computes rest length from current positions.

pub fn add_edge_with_length( &mut self, a: usize, b: usize, rest_length: f32, stiffness: f32, )

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

pub fn apply_impulse(&mut self, node: usize, impulse: Vec3)

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

Apply a radial explosion impulse from center.

pub fn node_count(&self) -> usize

pub fn edge_count(&self) -> usize
