Struct HyperBox 

pub struct HyperBox<const D: usize> {
    pub half_extents: [f64; D],
}

D-dimensional axis-aligned box centered at the origin.

half_extents[i] is the half-width along axis i. Total size along axis i = 2 * half_extents[i].

Fields

half_extents: [f64; D]

Implementations

impl<const D: usize> HyperBox<D>

pub fn new(half_extents: [f64; D]) -> Self

Create a box with the given half-extents per axis.

pub fn cube(half_extent: f64) -> Self

Create a uniform cube (all axes equal).

pub fn volume(&self) -> f64

Volume of the hyperbox: product of (2 * half_extent_i) for all axes.

pub fn contains_local(&self, point: &Point<D>) -> bool

Whether a local-space point is inside the box.

Trait Implementations

impl<const D: usize> Clone for HyperBox<D>

fn clone(&self) -> HyperBox<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const D: usize> Copy for HyperBox<D>

impl<const D: usize> Debug for HyperBox<D>

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

Formats the value using the given formatter.

impl<const D: usize> Shape<D> for HyperBox<D>

fn support(&self, direction: &SVector<f64, D>) -> SVector<f64, D>

Support function: support(d)[i] = sign(d[i]) * half_extents[i].

O(D) — no vertex enumeration. For a 4D tesseract, this is 4 operations instead of 16 (the vertex count of a tesseract).

fn bounding_sphere(&self) -> (Point<D>, f64)

Bounding sphere: (center, radius).

fn as_any(&self) -> &dyn Any

Downcast to concrete type for specialized collision dispatch.

fn clone_box(&self) -> Box<dyn Shape<D>>

Clone this shape into a new box.
