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()

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


ACTION BEHAVIOR
