Trait geo::algorithm::kernels::Kernel

pub trait Kernel<T: CoordNum> {
    fn orient2d(
        p: Coordinate<T>,
        q: Coordinate<T>,
        r: Coordinate<T>
    ) -> Orientation { ... }
    fn square_euclidean_distance(p: Coordinate<T>, q: Coordinate<T>) -> T { ... }
    fn dot_product_sign(u: Coordinate<T>, v: Coordinate<T>) -> Orientation { ... }
}

Kernel trait to provide predicates to operate on different scalar types.

Provided Methods

fn orient2d(p: Coordinate<T>, q: Coordinate<T>, r: Coordinate<T>) -> Orientation

Gives the orientation of 3 2-dimensional points: ccw, cw or collinear (None)

fn square_euclidean_distance(p: Coordinate<T>, q: Coordinate<T>) -> T

fn dot_product_sign(u: Coordinate<T>, v: Coordinate<T>) -> Orientation

Compute the sign of the dot product of u and v using robust predicates. The output is CounterClockwise if the sign is positive, Clockwise if negative, and Collinear if zero.
