Required Methods§

source

fn rhumb_intermediate(&self, other: &Point<T>, f: T) -> Point<T>

Returns a new Point along a rhumb line between two existing points.

§Examples
use geo::RhumbIntermediate;
use geo::Point;

let p1 = Point::new(10.0, 20.0);
let p2 = Point::new(125.0, 25.0);
let i20 = p1.rhumb_intermediate(&p2, 0.2);
let i50 = p1.rhumb_intermediate(&p2, 0.5);
let i80 = p1.rhumb_intermediate(&p2, 0.8);
let i20_should = Point::new(32.7, 21.0);
let i50_should = Point::new(67.0, 22.5);
let i80_should = Point::new(101.7, 24.0);
assert_relative_eq!(i20.x(), i20_should.x(), epsilon = 0.2);
assert_relative_eq!(i20.y(), i20_should.y(), epsilon = 0.2);
assert_relative_eq!(i50.x(), i50_should.x(), epsilon = 0.2);
assert_relative_eq!(i50.y(), i50_should.y(), epsilon = 0.2);
assert_relative_eq!(i80.x(), i80_should.x(), epsilon = 0.2);
assert_relative_eq!(i80.y(), i80_should.y(), epsilon = 0.2);
