       Constructor.
   SoNormalBundle::~SoNormalBundle () Destructor.

Member Function Documentation

   SbBool SoNormalBundle::shouldGenerate (int numneeded) Returns FALSE if
       there are normals on the state. Otherwise initGenerator() is called
       with numneeded as argument, and TRUE is returned.
   void SoNormalBundle::initGenerator (int initnum = 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 (int startindex = 0, SbBool addtostate = 1)
       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_t num, 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 (int index) const Returns the indexth
       normal from the state.
   void SoNormalBundle::send (int index) const Send the index’th normal to
       OpenGL.
