Type Alias LineSegment2 

pub type LineSegment2<T> = LineSegment<T, 2>;

Line segment in two dimensions

Aliased Type

pub struct LineSegment2<T> {
    pub start: Matrix<T, Const<2>, Const<1>, ArrayStorage<T, 2, 1>>,
    pub end: Matrix<T, Const<2>, Const<1>, ArrayStorage<T, 2, 1>>,
}

Fields

start: Matrix<T, Const<2>, Const<1>, ArrayStorage<T, 2, 1>>

One end of the line segment, the point returned when interpolating at t = 0.0

end: Matrix<T, Const<2>, Const<1>, ArrayStorage<T, 2, 1>>

One end of the line segment, the point returned when interpolating at t = 1.0

Implementations

impl<T> LineSegment2<T>

where T: Zero + One + Scalar + RealField,

pub fn bounds(&self) -> Rect<T>

where T: Number,

AABB for a 2D line segment

pub fn collinearity(&self, point: &Vector2<T>) -> T

Test whether a point is collinear with this segment.

• 0.0 means collinear. Near to 0.0 means near to collinear.
• Negative means that the point is to the counter-clockwise of end as viewed from start.
• Positive means that the point is to the clockwise of end as viewed from start.

pub fn intersects(&self, other: &LineSegment2<T>) -> bool

True if this segment intersects the given segment based on collinearity.
