DESCRIPTION

       This node specifies how the current materials are bound to shapes that follow in the scene
       graph. Each shape node may interpret bindings differently. The current material always has
       a base value, which is defined by the first value of all material fields.  Since  material
       fields  may  have multiple values, the binding determines how these values are distributed
       over a shape.

       The bindings for faces and vertices are meaningful only for  shapes  that  are  made  from
       faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow
       indexing.

       The bindings apply only to diffuse colors and transparency.   Other  materials  (emissive,
       specular,  ambient,  shininess)  will  have  the  first value applied to the entire shape,
       regardless of the material binding or the number provided.

       If the number of transparencies is less than the number of diffuse colors, only the  first
       transparency  value  will  be  used,  regardless of the material binding. If the number of
       diffuse colors in the state is less than the number required  for  the  given  binding,  a
       debug warning will be printed and unpredictable colors will result.

FIELDS

     SoSFEnum            value

METHODS

                         SoMaterialBinding()
          Creates a material binding node with default settings.

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

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction
          Sets the current material binding type.
