Detailed Description

       The SoVRMLNormal class is used to bind normals to geometry.

       The detailed class documentation is taken verbatim from the VRML97
       standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium,

         Normal {
           exposedField MFVec3f vector  []   # (-,)
         }
         .fi

       This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (e.g., SoVRMLIndexedFaceSet and SoVRMLElevationGrid). This node contains one multiple-valued field that contains the normal vectors. Normals shall be of unit length.

Member Function Documentation

   void SoVRMLNormal::initClass (void) [static] Sets up initialization for
       data common to all instances of this class, like submitting necessary
       information to the Coin type system.
       Reimplemented from SoNode.

   void SoVRMLNormal::doAction (SoAction * action) [virtual] This function
       performs the typical operation of a node for any action.
       Reimplemented from SoNode.

   void SoVRMLNormal::GLRender (SoGLRenderAction * action) [virtual] Action
       method for the SoGLRenderAction.
       This is called during rendering traversals. Nodes influencing the
       rendering state in any way or who wants to throw geometry primitives at
       OpenGL overrides this method.

       Reimplemented from SoNode.

   void SoVRMLNormal::callback (SoCallbackAction * action) [virtual] Action
       method for SoCallbackAction.
       Simply updates the state according to how the node behaves for the
       render action, so the application programmer can use the
       SoCallbackAction for extracting information about the scene graph.

       Reimplemented from SoNode.

   void SoVRMLNormal::pick (SoPickAction * action) [virtual] Action method for
       SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoVRMLNormal::getPrimitiveCount (SoGetPrimitiveCountAction * action)
       [virtual] Action method for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives
       for the node and adds these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count
       also overrides this method to change the relevant state variables.

       Reimplemented from SoNode.
