Implementations

impl CubicBezier

pub const fn new(p0: Point2D, p1: Point2D, p2: Point2D, p3: Point2D) -> Self

Create a new cubic Bezier curve.

pub fn evaluate(&self, t: f64) -> Point2D

Evaluate the curve at parameter t (0 to 1).

pub fn to_polyline(&self, segments: usize) -> Vec<Point2D>

Convert to a polyline with given number of segments.

pub fn arc_length(&self, segments: usize) -> f64

Compute approximate arc length.

pub fn split(&self, t: f64) -> (Self, Self)

Split curve at parameter t.

Trait Implementations

impl Clone for CubicBezier

fn clone(&self) -> CubicBezier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CubicBezier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CubicBezier

fn eq(&self, other: &CubicBezier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
