Struct Triangle 

pub struct Triangle { /* private fields */ }

A triangle in 3D space, defined by three vertices.

Implementations

impl Triangle

pub fn new(a: Point3<f32>, b: Point3<f32>, c: Point3<f32>) -> Self

Creates a new triangle from three points.

The winding order determines the normal direction via the right-hand rule: normal = (b - a) × (c - a)

pub fn vertices(&self) -> &[Point3<f32>; 3]

Returns the three vertices of the triangle.

pub fn normal(&self) -> Vector3<f32>

Computes the (unnormalized) normal vector of the triangle.

The direction follows the right-hand rule based on vertex winding.

pub fn unit_normal(&self) -> Option<Vector3<f32>>

Computes the unit normal vector of the triangle.

Returns None if the triangle is degenerate (zero area).

pub fn plane(&self) -> Plane3D

Returns the plane that this triangle lies on.

Panics

Panics if the triangle is degenerate (vertices are collinear).

pub fn centroid(&self) -> Point3<f32>

Computes the centroid (center of mass) of the triangle.

pub fn classify(&self, plane: &Plane3D) -> Classification

Classifies this triangle relative to a plane.

Returns:

• Front if all vertices are in front of the plane
• Back if all vertices are behind the plane
• Coplanar if all vertices lie on the plane
• Spanning if vertices are on both sides

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 Cuttable for Triangle

fn cut(&self, plane: &Plane3D) -> (Option<Polygon>, Option<Polygon>)

Cuts the geometry by a plane.

impl Debug for Triangle

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

Formats the value using the given formatter.

impl From<&Triangle> for Polygon

fn from(triangle: &Triangle) -> Self

Converts to this type from the input type.

impl From<&Triangle> for Plane3D

fn from(triangle: &Triangle) -> Self

Converts to this type from the input type.

impl From<Triangle> for Polygon

fn from(triangle: Triangle) -> Self

Converts to this type from the input type.

impl From<Triangle> for Plane3D

fn from(triangle: Triangle) -> Self

Converts to this type from the input type.

impl PartialEq for Triangle

fn eq(&self, other: &Triangle) -> 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.
