DESCRIPTION

       This node defines the lighting model to be used  when  rendering  subsequent  shapes.  The
       lighting model is specified in the model field. When the default model (Phong lighting) is
       used, light sources are required in a scene for objects to be easily visible.

FIELDS

     SoSFEnum            model
          Lighting model to use

METHODS

                         SoLightModel()
          Creates a light model node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction
          Sets the current lighting model in the state.

FILE FORMAT/DEFAULTS

       LightModel {
          model  PHONG
     }
