Struct Triangle3 

pub struct Triangle3 {
    pub a: Vec3,
    pub b: Vec3,
    pub c: Vec3,
}

3-D triangle with three vertices.

Fields

a: Vec3

First vertex.

b: Vec3

Second vertex.

c: Vec3

Third vertex.

Implementations

impl Triangle3

pub fn raw_normal(&self) -> Vec3

(Non-unit) normal via the right-hand rule (b-a) × (c-a).

pub fn normal(&self) -> Vec3

Unit normal. Returns [0, 0, 0] for degenerate triangles.

pub fn intersect_ray(&self, ray: &Ray3) -> Option<f64>

Möller–Trumbore ray-triangle intersection. Returns non-negative t.

pub fn closest_point(&self, p: Vec3) -> Vec3

Closest point on the triangle to p (Ericson, Real-Time Collision Detection, §5.1.5).

Trait Implementations

impl Clone for Triangle3

fn clone(&self) -> Triangle3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Triangle3

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

Formats the value using the given formatter.

impl PartialEq for Triangle3

fn eq(&self, other: &Triangle3) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
