Struct Triangle2D 

pub struct Triangle2D {
    pub a: [f32; 2],
    pub b: [f32; 2],
    pub c: [f32; 2],
}

A triangle defined by three 2D vertices.

Fields

a: [f32; 2]

b: [f32; 2]

c: [f32; 2]

Implementations

impl Triangle2D

pub fn new(a: [f32; 2], b: [f32; 2], c: [f32; 2]) -> Self

pub fn barycentric(&self, p: [f32; 2]) -> Option<[f32; 3]>

Compute barycentric coordinates (u, v, w) for point p. Returns None if the triangle is degenerate.

pub fn contains(&self, p: [f32; 2]) -> bool

Test if point p is inside the triangle.

pub fn interpolate(&self, values: [f32; 3], bary: [f32; 3]) -> f32

Interpolate a scalar value at barycentric coords (u, v, w).

pub fn signed_area(&self) -> f32

Area of the triangle (positive for CCW).

pub fn area(&self) -> f32

pub fn centroid(&self) -> [f32; 2]

Centroid of the triangle.
