Implementations

impl<T, D> Triangle<T, D>where
    T: Scalar,
    D: DimName,
    DefaultAllocator: Allocator<T, D>,

pub fn swap_vertices(&mut self, i: usize, j: usize)

pub fn edge(&self, index: usize) -> LineSegment<T, D>

impl<T, D> Triangle<T, D>where
    T: Real,
    D: DimName,
    DefaultAllocator: Allocator<T, D>,

pub fn centroid(&self) -> OPoint<T, D>

pub fn sides(&self) -> [OVector<T, D>; 3]

Returns an array of vectors corresponding to the three sides of the triangle.

impl<T> Triangle<T, Const<2>>where
    T: Real,

pub fn orientation(&self) -> Orientation

pub fn signed_area(&self) -> T

pub fn area(&self) -> T

impl<T> Triangle<T, Const<3>>where
    T: Real,

pub fn normal_dir(&self) -> Vector3<T>

Returns a vector normal to the triangle. The vector is not normalized.

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

pub fn orientation(&self) -> Orientation

TODO: Remove this. It makes no sense for 3D.

pub fn signed_area(&self) -> T

TODO: Remove this. It makes no sense for 3D (moreover, the current implementation gives the non-negative ara in any case).

pub fn area(&self) -> T

pub fn point_orientation(&self, point: &Point3<T>) -> OrientationTestResult

Determines the orientation of a point with respect to the plane containing the triangle.

This is the common “orientation test” used in computational geometry. The test returns a value whose sign is the same as dot(n, x - x0), where x0 is the projection of the point onto the triangle plane.

Note that at the moment, this implementation is NOT robust (in the sense of exact/robust geometric predicates).

impl<T: Real> Triangle<T, Const<3>>

pub fn compute_solid_angle(&self, p: &Point3<T>) -> T

Compute the solid angle to the given point.

fn clone(&self) -> Triangle<T, D>

Returns a copy of the value.

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

Formats the value using the given formatter.

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Triangle<T, Const<2>>> for ConvexPolygon<T>where

fn from(triangle: Triangle2d<T>) -> Self

Converts to this type from the input type.

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