Struct Sphere 

pub struct Sphere {
    pub c: Vector3,
    pub r: f64,
}

Fields

c: Vector3

r: f64

Implementations

impl Sphere

pub fn new(c: &Vector3, r: f64) -> Sphere

Creates a new Sphere. The sphere is defined by the center of the sphere, c, and the radius of the sphere, r.

Trait Implementations

impl Clone for Sphere

fn clone(&self) -> Sphere

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for Sphere

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Shape for Sphere

fn normal(&self, point: &Vector3) -> Vector3

Returns the normal (normalized) of the sphere at a given point (that should be in the surface of the sphere).

fn intersects(&self, line: &Line3) -> List<f64>

Returns the intersections of the sphere with a line. If the line doesn´t collide the sphere, it returns an empty list. If the line is tangent to the sphere, it returns a list with the single lambda value. If the line instersects the sphere, it returns a list with the two intersection lambdas. The lambda value is used to calculate the point of intersection with the line.calc_point(lambda).

fn closest_intersection(&self, line: &Line3) -> Option<Intersection>

Returns the closest positive intersection of the sphere with a line. If the line doesn´t collide the sphere, it returns Option None. If the line instersects the sphere, it returns the closest positive intersection lambda The lambda value is used to calculate the point of intersection with the line.calc_point(lambda).
