}
Expand description

Return type for the edge-edge intersection functions. Stores all possible results of an edge to edge intersection.

Note on coordinate types:

There are two coordinate types (which may be the same concrete type):

  • OriginalCoord is the coordinate type used to define the edge end-points. An intersection at the end-points can be expressed with this coordinate type.
  • IntersectionCoord is the coordinate type used to express intersection points somewhere in the middle of the edge. This may differ from the coordinate type of the end-points. For example if the end-points are stored in integer coordinates the intersection may require rational coordinates. But in special cases such as axis-aligned edges, the intersection point can indeed be expressed in integer coordinates.

Variants§

Point(Point<IntersectionCoord>)

Intersection in a single point but not on an endpoint of an edge.
