Implementations

impl BoundingSphere

pub fn new(center: impl Into<Vec3A>, radius: f32) -> Self

Constructs a bounding sphere from its center and radius.

pub fn from_point_cloud( translation: impl Into<Vec3A>, rotation: Quat, points: &[impl Copy + Into<Vec3A>], ) -> BoundingSphere

Computes a BoundingSphere containing the given set of points, transformed by translation and rotation.

The bounding sphere is not guaranteed to be the smallest possible.

pub fn radius(&self) -> f32

Get the radius of the bounding sphere

pub fn aabb_3d(&self) -> Aabb3d

Computes the smallest Aabb3d containing this BoundingSphere.

pub fn closest_point(&self, point: impl Into<Vec3A>) -> Vec3A

Finds the point on the bounding sphere that is closest to the given point.

If the point is outside the sphere, the returned point will be on the surface of the sphere. Otherwise, it will be inside the sphere and returned as is.

Trait Implementations

impl BoundingVolume for BoundingSphere
