pub struct Triangle<N: Real> { /* private fields */ }

A triangle shape.

Implementations

impl<N: Real> Triangle<N>

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

Creates a triangle from three points.

pub fn from_array(arr: &[Point<N>; 3]) -> &Triangle<N>

Creates the reference to a triangle from the reference to an array of three points.

pub fn a(&self) -> &Point<N>

The fist point of this triangle.

pub fn b(&self) -> &Point<N>

The second point of this triangle.

pub fn c(&self) -> &Point<N>

The third point of this triangle.

pub fn as_array(&self) -> &[Point<N>; 3]

Reference to an array containing the three vertices of this triangle.

pub fn normal(&self) -> Option<Unit<Vector<N>>>

The normal of this triangle assuming it is oriented ccw.

The normal points such that it is collinear to AB × AC (where × denotes the cross product).

pub fn scaled_normal(&self) -> Vector<N>

A vector normal of this triangle.

The vector points such that it is collinear to AB × AC (where × denotes the cross product).

Trait Implementations

impl<N: Clone + Real> Clone for Triangle<N>

fn clone(&self) -> Triangle<N>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N: Debug + Real> Debug for Triangle<N>

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

Formats the value using the given formatter.

impl<N: PartialEq + Real> PartialEq<Triangle<N>> for Triangle<N>

fn eq(&self, other: &Triangle<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N: Real> PointQuery<N> for Triangle<N>

fn project_point(
    &self,
    m: &Isometry<N>,
    pt: &Point<N>,
    solid: bool
) -> PointProjection<N>

Projects a point on self transformed by m.

fn project_point_with_feature(
    &self,
    m: &Isometry<N>,
    pt: &Point<N>
) -> (PointProjection<N>, FeatureId)

Projects a point on the boundary of self transformed by m and retuns the id of the feature the point was projected on.

fn distance_to_point(&self, m: &Isometry<N>, pt: &Point<N>, solid: bool) -> N

Computes the minimal distance between a point and self transformed by m.

fn contains_point(&self, m: &Isometry<N>, pt: &Point<N>) -> bool

Tests if the given point is inside of self transformed by m.

impl<N: Real> PointQueryWithLocation<N> for Triangle<N>

type Location = TrianglePointLocation<N>

Additional shape-specific projection information

fn project_point_with_location(
    &self,
    m: &Isometry<N>,
    pt: &Point<N>,
    solid: bool
) -> (PointProjection<N>, Self::Location)

Projects a point on self transformed by m.

impl<N: Real> SupportMap<N> for Triangle<N>

fn support_point(&self, m: &Isometry<N>, dir: &Vector<N>) -> Point<N>

Evaluates the support function of the object.

fn support_point_toward(
    &self,
    transform: &Isometry<N>,
    dir: &Unit<Vector<N>>
) -> Point<N>

Same as self.support_point except that dir is normalized.

impl<N: Real> ToPolyline<N> for Triangle<N>

type DiscretizationParameter = ()

fn to_polyline(&self, _: ()) -> Polyline<N>

Builds a triangle mesh from this shape.
