Struct bevy_math::bounding::Aabb3d

pub struct Aabb3d {
    pub min: Vec3,
    pub max: Vec3,
}

A 3D axis-aligned bounding box

Fields

min: Vec3

The minimum point of the box

max: Vec3

The maximum point of the box

Implementations

impl Aabb3d

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

Constructs an AABB from its center and half-size.

pub fn from_point_cloud( translation: Vec3, rotation: Quat, points: &[Vec3] ) -> Aabb3d

Computes the smallest Aabb3d containing the given set of points, transformed by translation and rotation.

Panics

Panics if the given set of points is empty.

pub fn bounding_sphere(&self) -> BoundingSphere

Computes the smallest BoundingSphere containing this Aabb3d.

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

Finds the point on the AABB that is closest to the given point.

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

Trait Implementations

impl BoundingVolume for Aabb3d

type Position = Vec3

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

type HalfSize = Vec3

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 Aabb3d

fn clone(&self) -> Aabb3d

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Aabb3d

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

Formats the value using the given formatter.

impl IntersectsVolume<Aabb3d> for Aabb3d

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

Check if a volume intersects with this intersection test

impl IntersectsVolume<Aabb3d> for AabbCast3d

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

Check if a volume intersects with this intersection test

impl IntersectsVolume<Aabb3d> for BoundingSphere

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

Check if a volume intersects with this intersection test

impl IntersectsVolume<Aabb3d> for RayCast3d

fn intersects(&self, volume: &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 Copy for Aabb3d
