<h4>Shader Parameters</h4>
-
<p>Programmable shaders define two types of parameters: uniform and
varying. As the names imply, uniform parameters are constant (within a
primitive), while varying parameters can vary on per-vertex or
per-fragment basis.

+ <li><b>Uniform parameters</b> (attributes) are those parameters whose
value is 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 parameters include a
transformation matrix, a texture map, lights, lookup tables,
etc.<br>
-<br>

+ <br>
We have created a new ShaderAttributeSet for allowing applications to
specify uniform shader attributes. 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
+value; and implicitly, by defining a binding between a Java&nbsp;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. See the javadoc for the new <a

shader program as pre-defined uniform attributes. The application
