Showing

void show ([string text = ""]) Function
If text is not the empty string (the default), it is printed on a line of its own to standard output. Otherwise, Line: is printed. Following this, Point::show() is called on position and direction.
          Point p(1, -2, 3);
          Point d(-12.3, 21, 36.002);
          Line L0(p, d);
          L0.show("L0:");
          -| L0:
             position: (1, -2, 3)
             direction: (-12.3, 21, 36.002)
          Line L1 = p.get_line(d);
          L1.show("L1:");
          -| L1:
             position: (1, -2, 3)
             direction: (-13.3, 23, 33.002)
          Path q = L1.get_path();
          q.show("q:");
          -| q:
             fill_draw_value == 0
             (1, -2, 3) -- (-12.3, 21, 36.002);
