NAME

       SoLightModel -

       The SoLightModel class is a node for specifying the model for geometry lighting.

       Use nodes of this type to set up how lighting should affect subsequent geometry in the scene.

SYNOPSIS

       #include <Inventor/nodes/SoLightModel.h>

       Inherits SoNode.

   Public Types
       enum Model { BASE_COLOR = SoLazyElement::BASE_COLOR, PHONG = SoLazyElement::PHONG }

   Public Member Functions
       virtual SoType getTypeId (void) const
           Returns the type identification of an object derived from a class inheriting SoBase. This is used for

Detailed Description

       The SoLightModel class is a node for specifying the model for geometry lighting.

       Use nodes of this type to set up how lighting should affect subsequent geometry in the scene.

       FILE FORMAT/DEFAULTS:

       LightModel {
           model PHONG
       }

Member Enumeration Documentation

   enum SoLightModel::Model
       Enumerates available light models.

       Enumerator

       BASE_COLOR
              Use  the  current  diffuse material color for subsequent geometry, and do not let any lightsources
              influence the appearance of the rendering primitives.

       PHONG  Use Phong-style shading for the geometry.

Constructor & Destructor Documentation

   SoLightModel::SoLightModel (void)
       Constructor.

   SoLightModel::~SoLightModel () [protected],  [virtual]
       Destructor.

Member Function Documentation

   SoType SoLightModel::getTypeId (void) const [virtual]
       Returns the type identification of an object derived from a class inheriting SoBase.  This  is  used  for
       run-time type checking and 'downward' casting. Usage example:

       void foo(SoNode * node)
       {
         if (node->getTypeId() == SoFile::getClassTypeId()) {
           SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
         }
       }

       For  application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or
       others: this method needs to be overridden in all subclasses. This is typically done as part  of  setting
       up  the  full  type  system for extension classes, which is usually accomplished by using the pre-defined
       macros   available   through   for   instance    Inventor/nodes/SoSubNode.h    (SO_NODE_INIT_CLASS    and
       SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

       For more information on writing Coin extensions, see the class documentation of the toplevel superclasses
       for the various class groups.

       Implements SoBase.

   const SoFieldData * SoLightModel::getFieldData (void) const [protected],  [virtual]
       Returns  a  pointer  to  the  class-wide  field  data  storage object for this instance. If no fields are
       present, returns NULL.

       Reimplemented from SoFieldContainer.

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

       Reimplemented from SoNode.

   void SoLightModel::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 SoLightModel::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.
