Struct mgf::Sphere

pub struct Sphere {
    pub c: Point3<f32>,
    pub r: f32,
}

A point and a distance.

Like AABBs, spheres are closed volumes.

Fields

c: Point3<f32>

The center point of the sphere.

r: f32

The radius of the sphere.

Methods

impl Sphere

pub fn new(center: Point3<f32>, radius: f32) -> Self

Create a new sphere.

Trait Implementations

impl Bound for Sphere

fn combine(a: &Sphere, b: &Sphere) -> Sphere

Produce a bound that encloses the two arguments.

fn surface_area(&self) -> f32

Return a measure of the area of the object.

impl BoundedBy<AABB> for Sphere

fn bounds(&self) -> AABB

impl BoundedBy<Sphere> for Triangle

fn bounds(&self) -> Sphere

impl BoundedBy<Sphere> for Rectangle

fn bounds(&self) -> Sphere

impl BoundedBy<Sphere> for AABB

Taking the bounding sphere of an AABB creates a sphere that contains all of the extreme points of the AABB. Thus, a bounding sphere for an AABB created from another bounding sphere will be larger in size than the original sphere.
