         * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.

         * If `enclose` is false, a ring surface is one element.
         * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.
