Struct Triangle 

pub struct Triangle {
    pub a: Vec3,
    pub b: Vec3,
    pub c: Vec3,
}

A triangle in 3D space.

Fields

a: Vec3

First vertex.

b: Vec3

Second vertex.

c: Vec3

Third vertex.

Implementations

impl Triangle

pub fn new(a: Vec3, b: Vec3, c: Vec3) -> Self

Create a new triangle.

pub fn normal_unnorm(&self) -> Vec3

Outward-facing normal (not normalised).

pub fn normal(&self) -> Vec3

Unit normal.

pub fn area(&self) -> Real

Area of the triangle.

pub fn centroid(&self) -> Vec3

Centroid of the triangle.

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

Möller–Trumbore ray–triangle intersection.

Returns Some(t) if the ray hits the front face, otherwise None.

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

Return the barycentric coordinates (u, v, w) of a point projected onto the triangle plane.

pub fn aabb(&self) -> Aabb

Axis-aligned bounding box of the triangle.

Trait Implementations

impl Clone for Triangle

fn clone(&self) -> Triangle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Triangle

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

Formats the value using the given formatter.
