The ill and ilp functions determine intersection points.
- ill(p1,p2,p3,p4)
-
Determines the intersection point between two lines (p1,p2) and (p3,p4). All points are considered three-dimensional.
- ilp(p1,p2,p3,p4,p5)
-
Determines the intersection point between a line (p1,p2) and a plane passing through three points (p3,p4,p5).
