Struct CompositeCurve 

pub struct CompositeCurve { /* private fields */ }

Multiple curve segments joined end-to-end.

Implementations

impl CompositeCurve

pub fn new() -> Self

pub fn add_weighted(self, seg: Box<dyn Curve>, weight: f32) -> Self

Add a segment with an explicit weight (relative length contribution).

pub fn add(self, seg: Box<dyn Curve>) -> Self

Add a segment with weight derived from arc length.

Trait Implementations

impl Curve for CompositeCurve

fn sample(&self, t: f32) -> Vec3

Sample position at parameter t ∈ [0, 1].

fn tangent(&self, t: f32) -> Vec3

Sample tangent (unnormalized derivative) at t.

fn unit_tangent(&self, t: f32) -> Vec3

Sample unit tangent at t.

fn normal_2d(&self, t: f32) -> Vec3

Sample the normal (perpendicular to tangent) at t, in the XY plane.

fn arc_length(&self, n: u32) -> f32

Approximate arc length using n segments.

fn build_arc_table(&self, n: u32) -> ArcTable

Build an arc-length table with n segments for uniform-speed queries.

fn sample_uniform(&self, n: usize) -> Vec<Vec3>

Sample n evenly-spaced points along the curve (by parameter).

fn sample_arc_uniform(&self, n: usize, table_resolution: u32) -> Vec<Vec3>

Sample n points at equal arc-length intervals.

fn bounding_box(&self, resolution: u32) -> (Vec3, Vec3)

Bounding box as (min, max).

fn closest_point(&self, query: Vec3, resolution: u32) -> (f32, Vec3)

Find the closest point on the curve to query, returning (t, point).

impl Default for CompositeCurve

fn default() -> Self

Returns the “default value” for a type.
