Tetrahedron

The center of a tetrahedron is the intersection of the lines from a vertex to the center of the opposite side. At least, in 3DLDF, this is the center of a Tetrahedron. I'm not 100 degrees certain that this is mathematically correct.

     Tetrahedron t(origin, 4);
     t.draw();
     t.get_center().dotlabel("$c$");
