[−] Expand description

A 2d curve segment defined by four points: the beginning of the segment, two control points and the end of the segment.

The curve is defined by equation:² ∀ t ∈ [0..1], P(t) = (1 - t)³ * from + 3 * (1 - t)² * t * ctrl1 + 3 * t² * (1 - t) * ctrl2 + t³ * to

Methods

impl CubicBezierSegment

fn sample(&self, t: f32) -> Vec2[−]

Sample the curve at t (expecting t between 0 and 1).

fn split(&self, t: f32) -> (CubicBezierSegment, CubicBezierSegment)[−]

Split this curve into two sub-curves.

fn before_split(&self, t: f32) -> CubicBezierSegment[−]

Return the curve before the split point.

fn after_split(&self, t: f32) -> CubicBezierSegment[−]

Return the curve after the split point.

fn flattening_iter(&self, tolerance: f32) -> CubicFlatteningIter[−]

Returns the flattened representation of the curve as an iterator, starting after the current point.

fn flattened_for_each<F: FnMut(Point)>(&self, tolerance: f32, call_back: &mut F)[−]

Iterates through the curve invoking a callback at each point.
