-| Polyhedron is defined by |
-| * a sequence of nodes defining all facets |
-| * a sequence of number of nodes per facet |
-| |
-| **Nodes**: |
-| Node1_of_Facet1, Node2_of_Facet1, ..., NodeN_of_Facet1, |
-| Node1_of_Facet2, Node2_of_Facet2, ..., NodeN_of_Facet2, |
-| Node1_of_FacetM, Node2_of_FacetM, ..., NodeN_of_FacetM |
-| |
-| **Quantity** of nodes per facet: |
-| NbNodes_in_Facet1, NbNodes_in_Facet2, ..., NbNodes_in_FacetM |
-| |
-| For example the polyhedron shown in the image below is defined by nodes |
-| [ 1,2,3, 1,4,5,2, 2,5,6,3, 3,6,4,1, 4,7,9,5, 5,9,8,6, 6,8,7,4, 7,8,9 ] |
-| and quantities [ 3, 4, 4, 4, 4, 4, 4, 3 ] |

-| Order of nodes of a facet must assure outward direction of its normal. |
