Detailed Description

VSG extension Abstract base class for all shader parameter nodes.

This is the abstract class from which all the shader parameter nodes are derived. There are two families of shader parameter nodes:

Each parameter is defined by one or both of the following properties:

There are two ways to specify the name of a parameter: using the field name to specify a string, or using the field identifier to specify an integer. This is because assembly languages (e.g., ARB_vertex_program/ARB_fragment_program) have index naming conventions rather than string naming conventions, whereas with Cg/GLSL, it is exactly the opposite. The two fields (name and identifier) allow specification of uniform parameters for both types of language. Depending on the language (ARB_, Cg, or GLSL), only one of the two fields will be used.

Specific subclasses add fields to hold a specific type of value.
