Implementations§

source§

impl BoundingSphere

source

pub fn new(center: Vec3, radius: f32) -> BoundingSphere

Constructs a bounding sphere from its center and radius.

source

pub fn from_point_cloud( translation: Vec3, rotation: Quat, points: &[Vec3] ) -> 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.

source

pub fn radius(&self) -> f32

Get the radius of the bounding sphere

source

pub fn aabb_3d(&self) -> Aabb3d

Computes the smallest Aabb3d containing this BoundingSphere.

source

pub fn closest_point(&self, point: Vec3) -> Vec3

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

§

type Position = Vec3

The position type used for the volume. This should be Vec2 for 2D and Vec3 for 3D.
