Trait piet_common::kurbo::ParamCurve[−]

pub trait ParamCurve {
    pub fn eval(&self, t: f64) -> Point;

    pub fn subsegment(&self, range: Range<f64>) -> Self;

    pub fn subdivide(&self) -> (Self, Self) { ... }

    pub fn start(&self) -> Point { ... }

    pub fn end(&self) -> Point { ... }
}

A curve parametrized by a scalar.

If the result is interpreted as a point, this represents a curve. But the result can be interpreted as a vector as well.

Required methods

pub fn eval(&self, t: f64) -> Point

Evaluate the curve at parameter t.

Generally t is in the range [0..1].

pub fn subsegment(&self, range: Range<f64>) -> Self

Get a subsegment of the curve for the given parameter range.
