   SoNormalBundle::~SoNormalBundle ()
       Destructor.

Member Function Documentation

   SbBool SoNormalBundle::shouldGenerate (intnumneeded)
       Returns FALSE if there are normals on the state. Otherwise initGenerator() is called with
       numneeded as argument, and TRUE is returned.

   void SoNormalBundle::initGenerator (intinitnum = 100)
       Initializes the normal generator. initnum is a hint that should contain the approximate
       number of normals to be generated.

   void SoNormalBundle::beginPolygon (void)
       Start polygon specification. Call polygonVertex() for each vertex in the polygon, and then
       endPolygon() to close the polygon.

       See Also:
           polygonVertex(), endPolygon()

   void SoNormalBundle::polygonVertex (const SbVec3f &v)
       Call for each vertex in a polygon.

       See Also:
           beginPolygon(), endPolygon()

   void SoNormalBundle::endPolygon (void)
       Call to close a polygon.

       See Also:
           beginPolygon(), polygonVertex()

   void SoNormalBundle::triangle (const SbVec3f &p1, const SbVec3f &p2, const SbVec3f &p3)
       Convenience method to specify a triangle. p1, p2, and p3 are the triangles vertices.

   void SoNormalBundle::generate (intstartindex = 0, SbBooladdtostate = TRUE)
       Generate normals for the shape. startindex should always be 0 (the
       SoNonIndexedShape::startIndex field is obsoleted). addtostate should be true if the
       generated normals should be pushed onto the current state.

   const SbVec3f * SoNormalBundle::getGeneratedNormals (void) const
       Returns the number of generated normals.

   int SoNormalBundle::getNumGeneratedNormals (void) const
       Returns a pointer to the generated normals.

   void SoNormalBundle::set (int32_tnum, const SbVec3f *normals)
       Can be used by nodes that generate their own normals. The state will be updated with the
       new normals, and the state will be popped again when the SoNormalBundle destructor is
       called.

   const SbVec3f & SoNormalBundle::get (intindex) const
       Returns the index'th normal from the state.

   void SoNormalBundle::send (intindex) const
       Send the index'th normal to OpenGL.
