Enum libreda_db::prelude::LineIntersection

pub enum LineIntersection<TP, TE> where
    TP: CoordinateType,
    TE: CoordinateType, {
    None,
    Point(Point<TP>, (TE, TE, TE)),
    Collinear,
}

Return type for the line-line intersection functions. Stores all possible results of a line to line intersection.

Variants

None

No intersection at all.

Point(Point<TP>, (TE, TE, TE))

Intersection in a single point. Besides the intersection point also an other expression for the intersection point is given. The three values (a, b, c) describe the intersection point in terms of a starting point (the starting point of the edge which defines the line) and the direction of the edge multiplied by a fraction.

edge.start + edge.vector()*a/c == p and other_edge.start + other_edge.vector()*b/c == p.

Collinear

Lines are collinear.
