ljoin (<point1>,<point2>,<point3>,<point4>)
point
The shortest line between two other lines. Two points are returned, the first lies on line1, the second lies on line two.
If the two lines lie in the same 3-D plane the result is the intersection of the lines and two identical points are returned.
<point1>,<point2>
Two point expressions defining the first line.
<point3>,<point4>
Two point expressions defining the second line.
point ps[2] = ljoin(p1,p2,p3,p4)
