Struct Aabb 

pub struct Aabb {
    pub min: [f64; 3],
    pub max: [f64; 3],
}

Axis-aligned bounding box in 3-D.

Fields

min: [f64; 3]

Minimum corner.

max: [f64; 3]

Maximum corner.

Implementations

impl Aabb

pub fn new(min: [f64; 3], max: [f64; 3]) -> Self

Create an AABB from its min and max corners.

pub fn from_points(pts: &[[f64; 3]]) -> Option<Self>

Create an AABB from a slice of points (returns None if empty).

pub fn contains(&self, p: [f64; 3]) -> bool

Test whether a point is inside (or on the boundary of) this AABB.

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

Smallest AABB that contains both self and other.

pub fn intersect(&self, other: &Aabb) -> Option<Aabb>

Intersection of two AABBs. Returns None if they do not overlap.

pub fn expand(&self, amount: f64) -> Aabb

Expand (or contract for negative amount) all sides by amount.

pub fn surface_area(&self) -> f64

Surface area of this AABB.

pub fn volume(&self) -> f64

Volume of this AABB.

pub fn centre(&self) -> [f64; 3]

Centre of this AABB.

pub fn half_extents(&self) -> [f64; 3]

Half-extents of this AABB.

pub fn intersect_ray( &self, origin: [f64; 3], dir: [f64; 3], ) -> Option<(f64, f64)>

Ray–AABB intersection test (slab method).

origin and dir define the ray; dir need not be normalised. Returns Some((t_enter, t_exit)) if the ray hits, otherwise None. Only positive-t intersections (in front of the origin) are reported.

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

Test whether another AABB overlaps this one.

impl Aabb

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

Merge two AABBs into the smallest AABB containing both.

Alias for Aabb::union.

pub fn expand_by(&self, amount: f64) -> Aabb

Expand this AABB by amount in every direction.

Alias for Aabb::expand following the task spec naming.

pub fn closest_point(&self, p: [f64; 3]) -> [f64; 3]

Return the closest point on (or inside) this AABB to p.

pub fn contains_point_strict(&self, p: [f64; 3]) -> bool

Test whether p is strictly inside (not on the boundary) of this AABB.

Trait Implementations

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 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.
