Struct fj_math::Triangle

#[repr(C)]
pub struct Triangle<const D: usize> { /* private fields */ }

A triangle

The dimensionality of the triangle is defined by the const generic D parameter.

Implementations

impl<const D: usize> Triangle<D>

pub fn from_points( points: [impl Into<Point<D>>; 3] ) -> Result<Self, NotATriangle<D>>

Construct a triangle from three points

Returns an error, if the points don’t form a triangle.

pub fn points(&self) -> [Point<D>; 3]

Access the triangle’s points

pub fn normalize(self) -> Self

Normalize the triangle

Returns a new Triangle instance with the same points, but the points ordered such that they are ordered according to their Ord/PartialOrd implementation.

This is useful for comparing triangles, where the order of points is not important.

impl Triangle<2>

pub fn winding(&self) -> Winding

Returns the direction of the line through the points of the triangle.

impl Triangle<3>

pub fn to_parry(self) -> Triangle

Convert the triangle to a Parry triangle

pub fn cast_local_ray( &self, origin: Point<3>, dir: Vector<3>, max_toi: f64, solid: bool ) -> Option<Scalar>

Cast a ray against the Triangle

pub fn normal(&self) -> Vector<3>

Compute the triangle’s normal

Trait Implementations

impl<const D: usize> Clone for Triangle<D>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const D: usize> Debug for Triangle<D>

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

Formats the value using the given formatter.

impl<const D: usize> Default for Triangle<D>

fn default() -> Triangle<D>

Returns the “default value” for a type.

impl<P, const D: usize> From<[P; 3]> for Triangle<D>

where P: Into<Point<D>>,

fn from(points: [P; 3]) -> Self

Converts to this type from the input type.

impl<const D: usize> Hash for Triangle<D>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const D: usize> Ord for Triangle<D>

fn cmp(&self, other: &Triangle<D>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<const D: usize> PartialEq for Triangle<D>

fn eq(&self, other: &Triangle<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.

impl<const D: usize> PartialOrd for Triangle<D>

fn partial_cmp(&self, other: &Triangle<D>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
