Struct BoundingBox3D 

pub struct BoundingBox3D {
    pub min_x: f64,
    pub min_y: f64,
    pub min_z: f64,
    pub max_x: f64,
    pub max_y: f64,
    pub max_z: f64,
}

An axis-aligned 3-D bounding box.

Invariant: min_x ≤ max_x, min_y ≤ max_y, min_z ≤ max_z. This invariant is enforced by BoundingBox3D::new.

Fields

min_x: f64

Minimum X coordinate.

min_y: f64

Minimum Y coordinate.

min_z: f64

Minimum Z coordinate.

max_x: f64

Maximum X coordinate.

max_y: f64

Maximum Y coordinate.

max_z: f64

Maximum Z coordinate.

Implementations

impl BoundingBox3D

pub fn new( min_x: f64, min_y: f64, min_z: f64, max_x: f64, max_y: f64, max_z: f64, ) -> Option<Self>

Construct a new bounding box.

Returns None if any min > max invariant is violated.

pub fn from_points(points: &[Point3D]) -> Option<Self>

Build the tightest bounding box that contains every point in points.

Returns None when points is empty.

pub fn contains(&self, p: &Point3D) -> bool

Return true when p is strictly inside or on the boundary.

pub fn intersects_2d(&self, other: &BoundingBox3D) -> bool

Return true when the XY footprints of self and other overlap (or touch).

pub fn intersects_3d(&self, other: &BoundingBox3D) -> bool

Return true when self and other share any volume (or face).

pub fn center(&self) -> (f64, f64, f64)

Centre point of the box as (cx, cy, cz).

pub fn diagonal(&self) -> f64

Length of the space diagonal (3-D).

pub fn expand_by(&self, delta: f64) -> Self

Return a box expanded symmetrically in every direction by delta.

If delta is negative the box may collapse; the result will still satisfy the min ≤ max invariant because f64 arithmetic naturally produces equal values when expansion < 0 produces min > max (the caller should validate the result if that matters).

pub fn volume(&self) -> f64

Volume of the box.

pub fn split_octants(&self) -> [BoundingBox3D; 8]

Subdivide the box into eight equal octant children.

Children are ordered by (x_high, y_high, z_high) bits: index 0 = (lo, lo, lo), index 7 = (hi, hi, hi).

Trait Implementations

impl Clone for BoundingBox3D

fn clone(&self) -> BoundingBox3D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundingBox3D

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

Formats the value using the given formatter.

impl PartialEq for BoundingBox3D

fn eq(&self, other: &BoundingBox3D) -> 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.
