Struct LineSegment2D 

pub struct LineSegment2D<Vec2: Vector2D> { /* private fields */ }

Trait for line segments in 2d space.

Implementations

impl<Vec2: Vector2D> LineSegment2D<Vec2>

pub fn new(start: Vec2, end: Vec2) -> Self

Creates a new line segment from two points.

pub fn start(&self) -> Vec2

Returns the start point of the line segment.

pub fn end(&self) -> Vec2

Returns the end point of the line segment.

pub fn length(&self) -> Vec2::S

Returns the length of the line segment.

pub fn length_squared(&self) -> Vec2::S

Returns the squared length of the line segment.

pub fn midpoint(&self) -> Vec2

Returns the midpoint of the line segment.

pub fn direction(&self) -> Vec2

Returns the direction of the line segment.

pub fn intersect_line( &self, other: &Self, eps: Vec2::S, eps2: Vec2::S, ) -> Option<Vec2>

Returns the intersection point of two line segments. eps is the epsilon for the cross product, i.e., for whether the lines are considered parallel. eps2 is the epsilon for the t and u values, i.e., for the line length.
