Uniform attributes (variables) are those attributes whose values are constant during the rendering of a primitive. Their values may change from primitive to primitive, but are constant for each vertex (for vertex shaders) or fragment (for fragment shaders) of a single primitive. Examples of uniform attributes include a transformation matrix, a texture map, lights, lookup tables, etc. The ShaderAttributeSet object contains a set of ShaderAttribute objects. Each ShaderAttribute object defines the value of a single uniform shader variable. The set of attributes is unique with respect to attribute names: no two attributes in the set will have the same name. <p> There are two ways in which values can be specified for uniform attributes: explicitly, by providing a value; and implicitly, by defining a binding between a Java 3D system attribute and a uniform attribute. This functionality is provided by two subclasses of ShaderAttribute: ShaderAttributeObject, which is used to specify explicitly defined attributes; and ShaderAttributeBinding, which is used to specify implicitly defined, automatically tracked attributes. <p> Depending on the shading language (and profile) being used, several Java 3D state attributes are automatically made available to the shader program as pre-defined uniform attributes. The application doesn't need to do anything to pass these attributes in to the shader program. The implementation of each shader language (e.g., Cg, GLSL) defines its own bindings from Java 3D attribute to uniform variable name. A list of these attributes for each shader language can be found in the concrete subclass of ShaderProgram for that shader language.<P><P><DL><DT><B>Since:</B></DT> <DD>Java 3D 1.4</DD><DT><B>See
