public class ShaderAttributeBinding
extends ShaderAttribute

The ShaderAttributeBinding object encapsulates a uniform attribute whose value is bound to a Java 3D system attribute. The shader variable attrName is implicitly set to the value of the corresponding Java 3D system attribute j3dAttrName during rendering. attrName must be the name of a valid uniform attribute in the shader in which it is used. Otherwise, the attribute name will be ignored and a runtime error may be generated. j3dAttrName must be the name of a predefined Java 3D system attribute. An IllegalArgumentException will be thrown if the specified j3dAttrName is not one of the predefined system attributes. Further, the type of the j3dAttrName attribute must match the type of the corresponding attrName variable in the shader in which it is used. Otherwise, the shader will not be able to use the attribute and a runtime error may be generated.

Following is the list of predefined Java 3D system attributes:

TODO: replace the following with the real system attributes table


Name	Type	Description
something	Float	This is something (of course)
somethingElse	Tuple3f	This is something else

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 mapping 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.
