       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

       SoIndexedFaceSet uses the indices in the coordIndex field (from SoIndexedShape) to specify
       the  polygonal  faces.  An index of SO_END_FACE_INDEX (-1) indicates that the current face
       has ended and the next one begins. 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 vertices of the faces are transformed by the current transformation matrix. 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.  PER_VERTEX  specifies  a
       material  or normal for each vertex. The corresponding _INDEXED bindings are the same, but
       use the materialIndex or normalIndex indices (see SoIndexedShape).  The  default  material
       binding is OVERALL. The default normal binding is PER_VERTEX_INDEXED.

       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.

       Textures are applied as described for the SoIndexedShape class.


          Creates an indexed 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.
