    pub v1: Point3<f64>,
    pub v2: Point3<f64>,
}

Triangle definition

Fields

v0: Point3<f64>

v1: Point3<f64>

v2: Point3<f64>

Implementations

impl Triangle

pub fn new(v0: Point3<f64>, v1: Point3<f64>, v2: Point3<f64>) -> Self

Create a new triangle

pub fn normal(&self) -> Vector3<f64>

Calculate triangle normal

pub fn cross_product(&self) -> Vector3<f64>

Calculate the cross product of edges, which is twice the area vector.

Returns a Vector3<f64> perpendicular to the triangle plane. For degenerate/collinear triangles, returns the zero vector. Use is_degenerate() or try_normalize() on the result if you need to detect and handle degenerate cases.

pub fn area(&self) -> f64

Calculate triangle area (half the magnitude of the cross product).

pub fn is_degenerate(&self, epsilon: f64) -> bool

Check if triangle is degenerate (zero area, collinear vertices).

Uses try_normalize on the cross product with the specified epsilon. Returns true if the cross product cannot be normalized (i.e., degenerate).

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.
