Function lineLineIntersection

lineLineIntersection(
    a: Point,
    b: Point,
    c: Point,
    d: Point,
    options?: { t1?: boolean },
): LineIntersection | null
An internal helper method for computing the intersection between two infinite-length lines. 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
- Optionaloptions: { t1?: boolean } = {}
  Options which affect the intersection test
  - Optionalt1?: boolean
    Return the optional vector distance from C to D on CD
Returns LineIntersection | null
An intersection point, or null if no intersection occurred
