Implementations

impl Triangle

pub const ZERO: Triangle

The empty Triangle at the origin.

pub const EQUILATERAL: Triangle

Equilateral Triangle with the x-axis unit vector as its base.

pub fn new( a: impl Into<Point>, b: impl Into<Point>, c: impl Into<Point>, ) -> Triangle

A new Triangle from three vertices (Points).

pub const fn from_coords( a: (f64, f64), b: (f64, f64), c: (f64, f64), ) -> Triangle

A new Triangle from three float vertex coordinates.

Works as a constant Triangle::new.

pub fn centroid(&self) -> Point

The centroid of the Triangle.

pub fn offsets(&self) -> [Vec2; 3]

The offset of each vertex from the centroid.

pub fn area(&self) -> f64

The area of the Triangle.

pub fn is_zero_area(&self) -> bool

Whether this Triangle has zero area.

pub fn inscribed_circle(&self) -> Circle

The inscribed circle of Triangle.

This is defined as the greatest Circle that lies within the Triangle.

pub fn circumscribed_circle(&self) -> Circle

The circumscribed circle of Triangle.

This is defined as the smallest Circle which intercepts each vertex of the Triangle.

pub fn inflate(&self, scalar: f64) -> Triangle

Expand the triangle by a constant amount (scalar) in all directions.

pub const fn is_finite(&self) -> bool

Is this Triangle finite?

pub const fn is_nan(&self) -> bool

Is this Triangle NaN?

Trait Implementations

impl Add<Vec2> for Triangle

type Output = Triangle

The resulting type after applying the + operator.

fn add(self, v: Vec2) -> Triangle

Performs the + operation.

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<(), Error>

Formats the value using the given formatter.

impl From<(Point, Point, Point)> for Triangle

fn from(points: (Point, Point, Point)) -> Triangle

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.

impl Shape for Triangle

type PathElementsIter<'iter> = TrianglePathIter

The iterator returned by the path_elements method.

fn path_elements(&self, _tolerance: f64) -> TrianglePathIter

Returns an iterator over this shape expressed as PathEls; that is, as Bézier path elements.

The winding number of a point.

fn bounding_box(&self) -> Rect

The smallest rectangle that encloses the shape.

fn to_path(&self, tolerance: f64) -> BezPath

fn into_path(self, tolerance: f64) -> BezPath

where Self: Sized,

Convert into a Bézier path.

fn path_segments(&self, tolerance: f64) -> Segments<Self::PathElementsIter<'_>>

Returns an iterator over this shape expressed as Bézier path segments (PathSegs).

fn contains(&self, pt: Point) -> bool

Returns true if the Point is inside this shape.

fn as_line(&self) -> Option<Line>
