Struct RawLine 

pub struct RawLine {
    pub points: [RawPoint; 2],
}

A straight line segment between two RawPoints.

Fields

points: [RawPoint; 2]

The two end points of the segment.

Implementations

impl RawLine

pub fn new(a: RawPoint, b: RawPoint) -> Self

Creates a segment between a and b.

pub fn distance(self) -> f32

Returns the Euclidean distance between the two end points.

pub fn midpoint(self) -> RawPoint

Returns the point halfway between the two end points.

pub fn distance_to_point(self, point: RawPoint) -> f32

Returns the Euclidean distance from point to the closest point on this segment.

The closest point is the perpendicular projection of point onto the segment’s supporting line, clamped to the segment itself; for a zero-length segment it is simply the distance to the endpoint.

Examples

use egui_map::map::objects::{RawLine, RawPoint};

let line = RawLine::new(RawPoint::new(0.0, 0.0), RawPoint::new(10.0, 0.0));
assert_eq!(line.distance_to_point(RawPoint::new(5.0, 3.0)), 3.0);
// Beyond the end of the segment, the endpoint is the closest point.
assert_eq!(line.distance_to_point(RawPoint::new(14.0, 0.0)), 4.0);
