Struct CapsuleChain 

pub struct CapsuleChain {
    pub points: Vec<[f64; 3]>,
    pub radius: f64,
}

A chain of capsule segments forming a rope / chain approximation.

Each consecutive pair of control points defines a capsule segment of the same radius.

Fields

points: Vec<[f64; 3]>

Control points of the chain (N points → N-1 segments).

radius: f64

Uniform radius for all segments.

Implementations

impl CapsuleChain

pub fn new(points: Vec<[f64; 3]>) -> Self

Create a chain from control points with zero radius.

pub fn with_radius(points: Vec<[f64; 3]>, radius: f64) -> Self

Create a chain with a specified radius.

pub fn segment_count(&self) -> usize

Number of capsule segments (one fewer than the number of points).

pub fn total_length(&self) -> f64

Total arc length of the chain (sum of segment lengths).

pub fn contains_point(&self, p: [f64; 3]) -> bool

Returns true if p is inside any capsule segment of the chain.

pub fn sdf(&self, p: [f64; 3]) -> f64

SDF: minimum signed distance to any segment surface.

pub fn min_distance_to_point(&self, p: [f64; 3]) -> f64

Minimum distance from p to the chain surface (negative if inside).
