public abstract class ShaderAttribute
extends NodeComponent

The ShaderAttribute object encapsulates a uniform attribute for a shader programs. 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.

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 as follows:
