+Some of 3D meshing algorithms also can generate 3D meshes from 2D meshes, working without
+geometrical objects. Such algorithms are
+<ul>
+<li>Hexahedron meshing algorithm (i,j,k),</li>
+<li>Tetrahedron (Netgen and GHS3D) meshing algorithms,</li>
+<li>Hexotic.</li>
+</ul>

\note BLSURF and GHS3D are commercial meshers and require a
license to be used within the Mesh module.
