Implementations

impl Aabb

pub fn new(a: Vec3, b: Vec3) -> Self

pub fn width(&self) -> f32

Return the length along the x axis.

pub fn height(&self) -> f32

Return the length along the y axis.

pub fn depth(&self) -> f32

Return the length along the z axis.

pub fn center(&self) -> Vec3

pub fn extents(&self) -> Vec3

pub fn diagonal_length(&self) -> f32

pub fn is_zero(&self) -> bool

pub fn union(a: Self, b: Self) -> Self

Returns the union of the two Aabbs.

pub fn is_outside_camera_view( &self, camera: &CameraDescriptor, transform: TransformDescriptor, ) -> bool

Determines whether this Aabb can be seen by camera after being transformed by transform.

pub fn get_mesh(&self) -> Vec<(Vec3, Vec3)>

Return a triangle mesh connecting this Aabb’s corners.

   y           1_____2     _____

  /           |    | /   | /    /
z/            |____|/   4|/____/5

7 is min
3 is max

pub fn intersects_aabb(&self, other: &Aabb) -> bool

Returns whether this Aabb intersects another Aabb.

Returns false if the two are touching, but not overlapping.

Trait Implementations

impl BVol for Aabb

fn get_aabb(&self) -> Aabb

Returns an AABB that contains the bounding volume.

fn culls_this_plane(&self, plane: &Vec4) -> bool

Checks if the given bounding volume is culled by this plane.

fn is_inside_frustum(&self, frustum: Frustum) -> bool

fn coherent_test_is_volume_outside_frustum( &self, frustum: &Frustum, lpindex: u32, ) -> (bool, u32)

Checks if bounding volume is outside the frustum “coherently”.

impl Clone for Aabb

fn clone(&self) -> Aabb

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Aabb

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

Formats the value using the given formatter.

impl Default for Aabb

fn default() -> Aabb

Returns the “default value” for a type.

impl From<(Vec3, Vec3)> for Aabb

fn from((a, b): (Vec3, Vec3)) -> Self

Converts to this type from the input type.

impl From<Aabb> for BoundingSphere

fn from(value: Aabb) -> Self

Converts to this type from the input type.

impl PartialEq for Aabb

fn eq(&self, other: &Aabb) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SlabItem for Aabb

where Vec3: SlabItem,

const SLAB_SIZE: usize = 6usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.
