    pub vertices: [Vec3; 3],

Expand description

A 3D triangle primitive.

Fields§

§vertices: [Vec3; 3]

The vertices of the triangle.

Implementations§

§

impl Triangle3d

pub fn new(a: Vec3, b: Vec3, c: Vec3) -> Triangle3d

Create a new Triangle3d from points a, b, and c.

pub fn normal(&self) -> Result<Dir3, InvalidDirectionError>

Get the normal of the triangle in the direction of the right-hand rule, assuming the vertices are ordered in a counter-clockwise direction.

The normal is computed as the cross product of the vectors ab and ac.

§Errors

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

pub fn is_degenerate(&self) -> bool

Checks if the triangle is degenerate, meaning it has zero area.

A triangle is degenerate if the cross product of the vectors ab and ac has a length less than 10e-7. This indicates that the three vertices are collinear or nearly collinear.

pub fn is_acute(&self) -> bool

Checks if the triangle is acute, meaning all angles are less than 90 degrees

pub fn is_obtuse(&self) -> bool

Checks if the triangle is obtuse, meaning one angle is greater than 90 degrees

pub fn reverse(&mut self)

Reverse the triangle by swapping the first and last vertices.

pub fn reversed(self) -> Triangle3d

This triangle but reversed.

pub fn centroid(&self) -> Vec3

Get the centroid of the triangle.

This function finds the geometric center of the triangle by averaging the vertices: centroid = (a + b + c) / 3.

pub fn largest_side(&self) -> (Vec3, Vec3)

Get the largest side of the triangle.

Returns the two points that form the largest side of the triangle.

pub fn circumcenter(&self) -> Vec3

Get the circumcenter of the triangle.

Trait Implementations§

§

impl Bounded3d for Triangle3d

§

fn aabb_3d(&self, translation: Vec3, rotation: Quat) -> Aabb3d

Get the bounding box of the triangle.

§

fn bounding_sphere(&self, translation: Vec3, _rotation: Quat) -> BoundingSphere

Get the bounding sphere of the triangle.

The Triangle3d implements the minimal bounding sphere calculation. For acute triangles, the circumcenter is used as the center of the sphere. For the others, the bounding sphere is the minimal sphere that contains the largest side of the triangle.
