Struct bevy_math::bounding::BoundingSphere

pub struct BoundingSphere {
    pub center: Vec3,
    pub sphere: Sphere,
}

A bounding sphere

Fields

center: Vec3

The center of the bounding sphere

sphere: Sphere

The sphere

Implementations

impl BoundingSphere

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

Constructs a bounding sphere from its center and radius.

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.

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: 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.

type HalfSize = f32

The type used for the size of the bounding volume. Usually a half size. For example an f32 radius for a circle, or a Vec3 with half sizes for x, y and z for a 3D axis-aligned bounding box

fn center(&self) -> Self::Position

Returns the center of the bounding volume.

fn half_size(&self) -> Self::HalfSize

Returns the half size of the bounding volume.

fn visible_area(&self) -> f32

Computes the visible surface area of the bounding volume. This method can be useful to make decisions about merging bounding volumes, using a Surface Area Heuristic.

fn contains(&self, other: &Self) -> bool

Checks if this bounding volume contains another one.

fn merge(&self, other: &Self) -> Self

Computes the smallest bounding volume that contains both self and other.

fn grow(&self, amount: Self::HalfSize) -> Self

Increase the size of the bounding volume in each direction by the given amount

fn shrink(&self, amount: Self::HalfSize) -> Self

Decrease the size of the bounding volume in each direction by the given amount

impl Clone for BoundingSphere

fn clone(&self) -> BoundingSphere

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoundingSphere

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntersectsVolume<Aabb3d> for BoundingSphere

fn intersects(&self, aabb: &Aabb3d) -> bool

Check if a volume intersects with this intersection test

impl IntersectsVolume<BoundingSphere> for Aabb3d

fn intersects(&self, sphere: &BoundingSphere) -> bool

Check if a volume intersects with this intersection test

impl IntersectsVolume<BoundingSphere> for BoundingSphere

fn intersects(&self, other: &Self) -> bool

Check if a volume intersects with this intersection test

impl IntersectsVolume<BoundingSphere> for BoundingSphereCast

fn intersects(&self, volume: &BoundingSphere) -> bool

Check if a volume intersects with this intersection test

impl IntersectsVolume<BoundingSphere> for RayCast3d

fn intersects(&self, volume: &BoundingSphere) -> bool

Check if a volume intersects with this intersection test

impl Copy for BoundingSphere
