Enum libreda_db::prelude::LineIntersection
pub enum LineIntersection<TP, TE>where
TP: CoordinateType,
TE: CoordinateType,{
None,
Point(Point<TP>, (TE, TE, TE)),
Collinear,
}
Expand description
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.
