Crate use_orientation 

use-orientation

Small 2D winding and collinearity helpers for the RustUse geometry workspace.

Example

use use_orientation::{Orientation2, orientation_2d};
use use_point::Point2;

assert_eq!(
    orientation_2d(
        Point2::new(0.0, 0.0),
        Point2::new(4.0, 0.0),
        Point2::new(0.0, 3.0),
    ),
    Orientation2::CounterClockwise,
);

Enums

Orientation2

The winding order of three 2D points.

Functions

orientation_2d_with_tolerance

Returns the winding order of three 2D points using an explicit area tolerance.

signed_twice_area_2d

Returns twice the signed area of the triangle formed by three 2D points.

try_orientation_2d

Returns the winding order of three 2D points with finite coordinates.

try_orientation_2d_with_tolerance
