pub struct Box {
    // some fields omitted
}

Geometry of a box.

Methods

impl Box

fn new(half_extents: V) -> Box

Creates a new box from its half-extents. Half-extents are the box half-width along each axis. Each half-extent must be greater than 0.04.

fn new_with_margin(half_extents: V, margin: N) -> Box

Creates a new box from its half-extents and its margin. Half-extents are the box half-width along each axis. Each half-extent must be greater than the margin.

impl Box

fn half_extents(&self) -> V

The half-extents of this box. Half-extents are the box half-width along each axis.

fn margin(&self) -> N

The margin surrounding this box.

Note that unlike most other geometries, a box has an interior margin. Therefore, the real extents of the box (those that have been passed to the Box constructor) equal the sum of the margin and its half-extents (as returned by the half_extents method).

fn toi_and_normal_with_transform_and_ray(&self, m: &M, ray: &Ray) -> Option<(N, V)>

Computes the time of impact, and normal between this transformed geometry and a ray.

fn intersects_with_transform_and_ray(&self, m: &M, ray: &Ray) -> bool

Tests whether a ray intersects this transformed geometry.

impl Volumetric for Box

fn mass_properties(&self, density: &N) -> (N, V, II)

Given a density, this computes the mass, center of mass, and inertia tensor of this object.

impl HasMargin for Box

fn margin(&self) -> N

The geometry margin.

impl<_M: Rotate<V> + Transform<V>> Implicit<V, _M> for Box

fn support_point_without_margin(&self, m: &_M, dir: &V) -> V

Evaluates the support function of the object. A support function is a function associating a vector to the geometry point which maximizes their dot product. This does not include the margin of the object. Margins are geometry-dependent. Use support_point to sample the complete geometry.

Arguments:

  • dir - the input of the support function. It is not required for it to be normalized.

fn support_point(&self, transform: &M, dir: &V) -> V

Evaluates the support function of the object. A support function is a function associating a vector to the geometry point which maximizes their dot product.

Arguments:

  • dir - the input of the support function. It is not required for it to be normalized.

impl<_M: Rotate<V>> PreferedSamplingDirections<V, _M> for Box

fn sample(&self, transform: &_M, f: |V|)

Applies a function to this geometry with a given transform.
