NAME

       SoNormal -

       The SoNormal class is a node for providing normals to the state.

       Coin will automatically calculate normals for you if no SoNormal nodes
       are present in the scene graph, but explicitly setting normals is
       useful for at least two purposes: 1) a potential increase in
       performance, 2) you can calculate and use ’incorrect’ normals to do
       various special effects.

Member Function Documentation

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

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

       Reimplemented from SoNode.

   void SoNormal::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.

Member Data Documentation

   SoMFVec3f SoNormal::vector Sets a pool of normal vectors in the traversal
       state.
