The TETRA_SURFACE function extracts a polygonal mesh as the exterior surface of a tetrahedral mesh. The output of this function is a polygonal mesh connectivity array that can be used with the input Verts array to display the outer surface of the tetrahedral mesh.
            Syntax
            Result = TETRA_SURFACE (Verts, Connin)
            Return Value
            Returns a polygonal mesh connectivity array. When used with the input vertex array, this function yields the exposed tetrahedral mesh surface.
            Arguments
            Verts
            Array of vertices [3, n].
            Connin
            Tetrahedral connectivity array.
            Keywords
            None.
