Module xenocollide 

Implementations of the Xenocollide collision detection algorithm.

collide2d and collide3d test for intersections between arbitrary geometries that implement the SupportMapping<Cartesian<2|3>> trait.

Example

In general, Xenocollide should be used via the IntersectsAt trait. However, the raw xenocollide methods can be used where needed.

use hoomd_geometry::{IntersectsAt, shape::Circle, xenocollide::collide2d};
use hoomd_vector::Angle;

let (s0, s1) = (
    Circle {
        radius: 1.0.try_into()?,
    },
    Circle {
        radius: 2.0.try_into()?,
    },
);
let displacement = [3.0; 2].into();
assert_eq!(
    collide2d(&s0, &s1, &displacement, &Angle::default()),
    s0.intersects_at(&s1, &displacement, &Angle::default())
);

Functions
