point2  2d/3d point list; end point of first line

point3  2d/3d point list; start point of second line

point4  2d/3d point list; end point of second line

onlyOnSegment  (optional) if non-NIL, the intersection must be on both segments, otherwise infinite lines are used for intersection point calculation; defaultNIL, infinite lines are used

Return
