       This  node  represents  a  3D  shape formed by constructing faces (polygons) from vertices
       located at the coordinates specified in the vertexProperty field (from SoVertexShape),  or
       the  current  inherited  state.  For  optimal  performance,  the  vertexProperty  field is

       SoFaceSet uses the coordinates in order, starting with the first  one.  Each  face  has  a
       number  of  vertices  specified  by  a  value  in  the  numVertices field. For example, an
       SoFaceSet with numVertices of [3,4,4] would use coordinates 1, 2,  and  3  for  the  first
       face, coordinates 4, 5, 6, and 7 for the second face, and coordinates 8, 9, 10, and 11 for
       the third. For improved performance, arrange  all  the  faces  with  only  3  vertices  at
       beginning of the list, then all faces with 4 vertices, and finally all other faces.

       The number of values in the numVertices field indicates the number of faces in the set.

       The  coordinates of the face set are transformed by the current cumulative transformation.
       The faces are drawn with the current light model and drawing style.

       Treatment of the current material and normal binding  is  as  follows:  The  PER_PART  and
       PER_FACE  bindings  specify  a material or normal for each face. The _INDEXED bindings are
       equivalent to their non-indexed counterparts. The default material binding is OVERALL. The
       default normal binding is PER_VERTEX.

       If  any  normals  (or  materials)  are specified, Inventor assumes you provide the correct
       number of them, as indicated by the binding.  You  will  see  unexpected  results  if  you
       specify fewer normals (or materials) than the shape requires. If no normals are specified,
       they will be generated automatically.

          Number of vertices per face.


          Creates a face set node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


          Draws faces based on the current coordinates, normals, materials, drawing style, and so

          Picks  faces  based  on  the  current coordinates and transformation. Details about the
          intersection are returned in an SoFaceDetail.

          Computes the bounding box that encloses all vertices of the face set with  the  current
          transformation  applied  to  them. Sets the center to the average of the coordinates of
          all vertices.

          If any triangle callbacks are registered with the action, they will be invoked for each
          successive triangle generated from each face in the set.
