Struct CubicBezier2d 

pub struct CubicBezier2d { /* private fields */ }

A cubic bezier curve

Implementations

impl CubicBezier2d

pub const fn new(points: &[Point2d; 4]) -> Self

Creates a new cubic bezier curve that passes through the provided control points.

pub fn line(start: Point2d, end: Point2d) -> Self

Creates a cubic bezier curve which is a straight line passing through the given endpoints.

pub fn quadratic(points: &[Point2d; 3]) -> Self

Creates a cubic bezier curve which is identical to the quadratic bezier curve that passes through the provided control points.

pub fn subdivide(&self, t: f64) -> [CubicBezier2d; 2]

Subdivide the curve into two sub curves at the value t.

pub fn reverse(&mut self)

Reverses the order of the control points in the bezier curve, such that the point which at t=0 is now at t=1 and vise versa.
