Fields

center: Vec3A

The center of the bounding sphere

sphere: Sphere

The sphere

Implementations

impl BoundingSphere

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

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

type Translation = Vec3A

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

type Rotation = Quat

The rotation type used for the volume. This should be f32 for 2D and Quat 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) -> <BoundingSphere as BoundingVolume>::Translation

Returns the center of the bounding volume.

fn half_size(&self) -> <BoundingSphere as BoundingVolume>::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: &BoundingSphere) -> bool

Checks if this bounding volume contains another one.

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

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

fn grow( &self, amount: impl Into<<BoundingSphere as BoundingVolume>::HalfSize> ) -> BoundingSphere

Increases the size of the bounding volume in each direction by the given amount.

fn shrink( &self, amount: impl Into<<BoundingSphere as BoundingVolume>::HalfSize> ) -> BoundingSphere

Decreases the size of the bounding volume in each direction by the given amount.

fn scale_around_center( &self, scale: impl Into<<BoundingSphere as BoundingVolume>::HalfSize> ) -> BoundingSphere

Scale the size of the bounding volume around its center by the given amount

fn translate_by( &mut self, translation: impl Into<<BoundingSphere as BoundingVolume>::Translation> )

Translates the bounding volume by the given translation.

fn rotate_by( &mut self, rotation: impl Into<<BoundingSphere as BoundingVolume>::Rotation> )

Rotates the bounding volume around the origin by the given rotation.

fn transformed_by( self, translation: impl Into<Self::Translation>, rotation: impl Into<Self::Rotation> ) -> Self

Transforms the bounding volume by first rotating it around the origin and then applying a translation.

fn transform_by( &mut self, translation: impl Into<Self::Translation>, rotation: impl Into<Self::Rotation> )

Transforms the bounding volume by first rotating it around the origin and then applying a translation.

fn translated_by(self, translation: impl Into<Self::Translation>) -> Self

Translates the bounding volume by the given translation.

fn rotated_by(self, rotation: impl Into<Self::Rotation>) -> Self

Rotates the bounding volume around the origin by the given rotation.

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<(), Error>
