Struct Aabb3 

pub struct Aabb3 {
    pub min: Point3,
    pub max: Point3,
}

A 3D axis-aligned bounding box.

Fields

min: Point3

Minimum corner.

max: Point3

Maximum corner.

Implementations

impl Aabb3

pub fn from_points(points: impl IntoIterator<Item = Point3>) -> Self

Create an AABB from an iterator of points.

Panics

Panics if the iterator is empty. Use Aabb3::try_from_points for a fallible version.

pub fn try_from_points(points: impl IntoIterator<Item = Point3>) -> Option<Self>

Create an AABB from an iterator of points, returning None if empty.

pub fn intersects(self, other: Self) -> bool

Whether this box intersects another.

pub fn contains_point(self, p: Point3) -> bool

Whether this box contains a point.

pub const fn union(self, other: Self) -> Self

Compute the union of two bounding boxes.

pub fn expanded(self, margin: f64) -> Self

Return a new box expanded by margin on each side.

pub fn surface_area(self) -> f64

Surface area of the box (used for SAH cost in BVH).

pub fn center(self) -> Point3

Center point of the bounding box.

pub fn line_intersects(self, origin: Point3, dir: Vec3) -> bool

Whether the whole line through origin along dir, both ways, meets this box (touching counts).

A zero direction component is tested by the origin’s coordinate alone, so an origin lying on a face of the box with the line in that face still meets it.

pub fn ray_intersects(self, origin: Point3, inv_dir: Vec3) -> bool

Test whether a ray (origin + positive-t direction) intersects this box.

Uses the slab method. Returns true if the ray hits the box at any t >= 0.

pub fn distance_squared_to_point(self, p: Point3) -> f64

Squared distance from a point to the closest point on the box.
