Function lineSegmentIntersection

lineSegmentIntersection(
    a: Point,
    b: Point,
    c: Point,
    d: Point,
    epsilon?: number,
): LineIntersection | null
An internal helper method for computing the intersection between two finite line segments. Adapted from http://paulbourke.net/geometry/pointlineplane/
Parameters
- a: Point
  The first endpoint of segment AB
- b: Point
  The second endpoint of segment AB
- c: Point
  The first endpoint of segment CD
- d: Point
  The second endpoint of segment CD
- Optionalepsilon: number = 1e-8
  A small epsilon which defines a tolerance for near-equality
Returns LineIntersection | null
An intersection point, or null if no intersection occurred
