SoPrimitiveVertex — represents a vertex of a generated primitive

       An  SoPrimitiveVertex represents a vertex of a primitive (triangle, line segment, or point) that is being
       generated by an SoCallbackAction.  It  contains  an  object-space  point,  normal,  texture  coordinates,
       material  index,  and  a  pointer  to  an  instance of an SoDetail subclass. This detail may contain more
       information about the vertex, or may be a NULL pointer if there is no such info.

       Instances of SoPrimitiveVertex are typically created on  the  stack  by  shape  classes  while  they  are
       generating  primitives.  Anyone  who  wants  to  save  them as return values from SoCallbackAction should
       probably make copies of them.

          Constructors and destructor. Note that copying a primitive vertex copies the detail pointer,  and  not
          the detail itself.

     constSbVec3f&getPoint()constconstSbVec3f&getNormal()constconstSbVec4f&getTextureCoords()const
          These return the surface point, normal, and texture coordinates in object space.

     intgetMaterialIndex()const
          Returns the index into the current set of materials of the material active at the vertex.

     constSoDetail*getDetail()const
          Returns  the  detail  giving  more information about the vertex. Note that this pointer may be NULL if
          there is no more info.

     SoPrimitiveVertex&operator=(constSoPrimitiveVertex&pv)
          Copies the given vertex. Note that just the pointer to the  detail  is  copied,  and  not  the  detail
          itself.

                                                                                        SoPrimitiveVertex(3IV)()
