Struct Vertex3

pub struct Vertex3<T: CoordsFloat>(pub T, pub T, pub T);

3D vertex representation

Generics

• T: CoordsFloat – Generic type for coordinates representation.

Example

use honeycomb_core::geometry::{Vector3, Vertex3};

let v1 = Vertex3(1.0, 0.0, 0.0);
let v2 = Vertex3(1.0, 1.0, 1.0);

assert_eq!(v1.x(), 1.0);
assert_eq!(v1.y(), 0.0);
assert_eq!(v1.z(), 0.0);

let two: f64 = 2.0;
// vectorAB = vertexB - vertexA
let v2_minus_v1: Vector3<f64> = v2 - v1;

assert_eq!(v2_minus_v1.norm(), two.sqrt());
assert_eq!(v2_minus_v1.unit_dir()?, Vector3(0.0, 1.0 / two.sqrt(), 1.0 / two.sqrt()));

let mut v3 = Vertex3(0.0, 1.0, 1.0);
// vertexA + vectorB = vertexA'
v3 += v2_minus_v1;

assert_eq!(v3.x(), 0.0);
assert_eq!(v3.y(), 2.0);
assert_eq!(v3.z(), 2.0);

Implementations

impl<T: CoordsFloat> Vertex3<T>

pub fn into_inner(self) -> (T, T, T)

Consume self to return inner value

Return

Return coordinate values as a simple tuple.

pub fn x(&self) -> T

Getter

Return

Return the value of the x coordinate of the vertex.

pub fn y(&self) -> T

Getter

Return

Return the value of the y coordinate of the vertex.

pub fn z(&self) -> T

Getter

Return

Return the value of the z coordinate of the vertex.

pub fn average(lhs: &Vertex3<T>, rhs: &Vertex3<T>) -> Vertex3<T>

Compute the mid-point between two vertices.

Return

Return the mid-point as a new Vertex3 object.

Panics

This function may panic if it cannot initialize an object T: CoordsFloat from the value 2.0. The chance of this happening when using T = f64 or T = f32 is most likely zero.

Example

use honeycomb_core::geometry::Vertex3;

let far_far_away: Vertex3<f64> = Vertex3(2.0, 2.0, 2.0);
let origin: Vertex3<f64> = Vertex3::default();

assert_eq!(Vertex3::average(&origin, &far_far_away), Vertex3(1.0, 1.0, 1.0));
