Introduction
The Cg Toolkit provides a compiler for the Cg 2.0 language, runtime libraries for use with both leading graphics APIs, runtime libraries for CgFX, example applications, and extensive documentation. Supporting over 25 different OpenGL and DirectX profile targets, Cg 2.0 will allow you to incorporate stunning interactive effects into your 3D applications.
The components include:

• NVIDIA Cg Compiler Release 2.0
• Cg/CgFX Runtime libraries for OpenGL and Direct3D
• Cg User's Manual
• Documentation for the Cg
• Language Specification, runtime APIs, Cg standard library, CgFX states, and the Cg profiles.
• Cg examples

Cg 2.0 supports a broad range of desktop operating systems (Windows 2000, XP, Vista, Mac OS X for Tiger and Leopard, 32-bit and 64-bit x86 Linux, and x86 Solaris) so your shader-enabled applications can use the same shaders no matter your choice of operating system or graphics API.
We hope that you will enjoy the exciting world of Cg programming.
Latest Cg Toolkit Features
The 2.0 release of Cg introduces several new features and improvements:

• New OpenGL profiles (gp4vp, gp4gp, and gp4fp) for GeForce 8 extensions
• These expose new DirectX 10-class features including geometry shaders, bindable constant buffers for uniforms, texture arrays, first-class integer support and more
• Support for Apple's new "Leopard" release of Mac OS X 10.5
• New DirectX 9 profiles (hlslv and hlslf) to cross-translate Cg to HLSL
• Documentation updates, including Cg Standard Library and standard CgFX states
• New examples demonstrating texture-space bump mapping setup via a geometry shaders, shadow volume generation via a geometry shader, bindable constant buffers, and more
• Improved compiler code generation
• Runtime performance improvements
• Compatibility with Cg 1.5

Please see the release notes for details, known issues, and more.

在HLSL和GLSL的夹击下，Cg继续存在的理由是什么？:huh:
