Struct Triangle3 

pub struct Triangle3 {
    pub v: [[f64; 3]; 3],
}

A 3D triangle with three vertices.

Fields

v: [[f64; 3]; 3]

Vertices of the triangle.

Implementations

impl Triangle3

pub fn new(v0: [f64; 3], v1: [f64; 3], v2: [f64; 3]) -> Self

Create from three vertices.

pub fn normal_raw(&self) -> [f64; 3]

Outward normal (not normalized).

pub fn normal(&self) -> [f64; 3]

Unit normal.

pub fn area(&self) -> f64

Area of the triangle.

pub fn centroid(&self) -> [f64; 3]

Centroid.

pub fn barycentric_coords(&self, p: [f64; 3]) -> (f64, f64, f64)

Compute barycentric coordinates (u, v, w) of point p projected onto triangle.

pub fn contains_point_2d(&self, p: [f64; 3]) -> bool

Check if a point (projected) lies within the triangle (u, v, w ≥ 0).
