Struct parametrics::circle::Circle

pub struct Circle {
    pub centre: Point,
    pub radius: f32,
    pub start_angle: T,
}

A circle of radius r, centred at a point - parameterisation starting at a given “angle” measured in “turns” (so [0,1]) - where 0 is on the positive x-axis for the unit circle.

Fields

centre: Point

radius: f32

start_angle: T

Implementations

impl Circle

pub fn new(centre: Point, radius: f32, start_angle: Option<T>) -> Self

Trait Implementations

impl ParametricFunction2D for Circle

fn evaluate(&self, t: T) -> Point

returns the value of the parametric function at the point t

fn linspace(&self, n: usize) -> Vec<Point>

returns n equally spaced points along the entire parametric function from T::start to T::end

fn start(&self) -> Point

returns start, or “first”, point on the parametric function

fn end(&self) -> Point

returns end, or“last“, point on the parametric function

fn random_point(&self) -> Point

return a random point on the parametric function

fn random_points(&self, n: usize) -> Vec<Point>

return n random points on the parametric function
