Function cavalier_contours::core::math::point_within_arc_sweep

pub fn point_within_arc_sweep<T>(
    center: Vector2<T>,
    arc_start: Vector2<T>,
    arc_end: Vector2<T>,
    is_clockwise: bool,
    point: Vector2<T>,
    epsilon: T
) -> bool
where
    T: Real,

Test if a point is within a arc sweep angle region.

Arc is defined by center, arc_start, arc_end, and arc direction parameter is_clockwise. The angle region is defined as if the arc had infinite radius projected outward in a cone.

epsilon is used for fuzzy comparing.

Examples

// defining an arc that projects an angle region covering all of
// quadrant I (x positive, y positive space)
let arc_center = Vector2::new(0.0, 0.0);
let arc_start = Vector2::new(1.0, 0.0);
let arc_end = Vector2::new(0.0, 1.0);
assert!(
    point_within_arc_sweep(arc_center, arc_start, arc_end, false, Vector2::new(1.0, 1.0), 1e-5)
);
// check is fuzzy inclusive
assert!(
    point_within_arc_sweep(arc_center, arc_start, arc_end, false, Vector2::new(1.0, 0.0), 1e-5)
);
assert!(
    point_within_arc_sweep(arc_center, arc_start, arc_end, false, Vector2::new(0.0, 1.0), 1e-5)
);
