Struct BoundingSphere

pub struct BoundingSphere {
    pub center: Vec3,
    pub radius: f32,
}

Bounding sphere consisting of a center and radius.

Fields

center: Vec3

radius: f32

Implementations

impl BoundingSphere

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

Creates a new bounding sphere.

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

Determine whether this sphere is inside the camera’s view frustum after being transformed by transform.

pub fn project_by(&self, view_projection: &Mat4) -> Self

Transform this BoundingSphere by the given view projection matrix.

pub fn project_onto_viewport( &self, camera: &CameraDescriptor, viewport: Vec2, ) -> Aabb

Returns an Aabb with x and y coordinates in viewport pixels and z coordinate in NDC depth.

Trait Implementations

impl BVol for BoundingSphere

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 BoundingSphere

fn clone(&self) -> BoundingSphere

Returns a duplicate 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 Default for BoundingSphere

fn default() -> BoundingSphere

Returns the “default value” for a type.

impl From<(Vec3, Vec3)> for BoundingSphere

fn from((min, max): (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 BoundingSphere

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

where Vec3: SlabItem, f32: SlabItem,

const SLAB_SIZE: usize = 4usize

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.
