Trait Parametric 

pub trait Parametric<T> {
    // Required method
    fn eval(&self, t: f32) -> T;
}

Represents a single-variable parametric curve.

Required Methods

fn eval(&self, t: f32) -> T

Returns the value of self at t.

The “canonical” domain of this function is t ∈ [0.0, 1.0], but implementations should return “reasonable” values outside the unit interval as well.

Implementations on Foreign Types

impl<T: Lerp> Parametric<T> for Range<T>

fn eval(&self, t: f32) -> T

Linearly interpolates between self.start and self.end.

Equivalent to <Self as Lerp>::lerp(&self.start, &self.end, t).

See also Lerp::lerp.

Examples

use core::ops::Range;
use retrofire_core::math::{Parametric, pt2, Point2};

let range: Range<Point2> = pt2(-2.0, 1.0)..pt2(3.0, 2.0);

assert_eq!(range.eval(0.0), range.start);
assert_eq!(range.eval(0.5), pt2(0.5, 1.5));
assert_eq!(range.eval(1.0), range.end);
