Struct Aabb 

pub struct Aabb {
    pub min: Vec3,
    pub max: Vec3,
}

Axis-aligned bounding box for broad-phase collision detection.

Fields

min: Vec3

Minimum corner of the bounding box.

max: Vec3

Maximum corner of the bounding box.

Implementations

impl Aabb

pub fn new(min: Vec3, max: Vec3) -> Self

Create a new AABB from min and max corners.

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

Check whether this AABB intersects another.

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

Merge this AABB with another, returning the smallest AABB containing both.

pub fn contains_point(&self, point: &Vec3) -> bool

Check if a point is inside the AABB.

pub fn expand(&self, margin: Real) -> Self

Expand the AABB by a margin in all directions.

pub fn center(&self) -> Vec3

Center of the AABB.

pub fn half_extents(&self) -> Vec3

Half-extents of the AABB.

pub fn surface_area(&self) -> Real

Surface area of the AABB.

pub fn volume(&self) -> Real

Volume of the AABB.

impl Aabb

pub fn from_center_half_extents(center: Vec3, half_extents: Vec3) -> Self

Create an AABB from a center point and half-extents.

pub fn from_points(points: &[Vec3]) -> Option<Self>

Create an AABB enclosing a set of points.

pub fn longest_axis(&self) -> usize

Longest axis (0=x, 1=y, 2=z).

pub fn diagonal(&self) -> f64

Diagonal length of the AABB.

impl Aabb

pub fn ray_intersect(&self, ray: &Ray) -> Option<RayAabbHit>

Test whether ray intersects this AABB using the slab method.

Returns Some(hit) with the entry/exit t values if the ray hits, or None if it misses. Handles degenerate (zero-direction) rays.

pub fn ray_hit_t(&self, ray: &Ray) -> Option<Real>

Test ray against AABB and return just the entry t (simpler API).

pub fn swept_aabb(half_extents: Vec3, from: &Transform, to: &Transform) -> Aabb

Compute the AABB of the swept volume as the box moves from transform_a to transform_b (uses the merge of two oriented boxes).

pub fn oriented_box_aabb(half_extents: Vec3, transform: &Transform) -> Aabb

Compute the AABB enclosing an oriented box (defined by half-extents and a transform).

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

Compute the intersection (overlap) AABB of two boxes.

Returns None if the boxes do not overlap.

pub fn sq_distance_to_point(&self, point: &Vec3) -> Real

Compute the squared distance from a point to the nearest point on the AABB surface.

Returns 0 if the point is inside the AABB.

pub fn closest_point(&self, point: &Vec3) -> Vec3

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