NVIDIA Cg Toolkit Documentation for cg210009. Cg210009 - Cg Toolkit 2.1 August 2008 (beta). New translation profiles for DirectX10 Shader Model 4. See here for important information about Cg. Cg Toolkit 3.1 - April 2012 (3.1.0013) Windows 32/64-bit installer for Windows XP, Vista and Win7. Mac OS X ppc/i386/x8664 dmg for Tiger, Leopard and Snow Leopard. Linux 32-bit tgz tarball rpm for RedHat deb for Debian and Ubuntu. Linux 64-bit tgz tarball rpm for RedHat deb for Debian and Ubuntu. NVIDIA Cg Toolkit Documentation for cg220017. Cg220017 - Cg Toolkit 2.2 February 2010. Require EXTgpushader4 in GLSL when using bit shift/mask instructions. GLUT provides a cross-platform window system API for writing OpenGL examples and demos. For this reason, the Cg examples packaged with the Cg Toolkit rely on GLUT. Windows Installation. The Cg Toolkit installer for Windows provides a pre-compiled 32-bit (and 64-bit if selected) versions of GLUT. Distribution of the Maya Cg Plugin has been taken over directly by Autodesk/Alias since the advent of Maya 6. If you have Maya version 6, 7, 8, 2008 or beyond, this plugin already came along as part of your Maya installation so you won't need to download it here. To enable the Cg Plugin in newer versions of Maya, simply find it in the Maya plugin manager.

Status of Cg?
The Cg Toolkit is a legacy NVIDIA toolkit no longer under active development or support. Cg 3.1 is our last release and while we continue to make it available to developers, we do not recommend using it in new development projects because future hardware features may not be supported.
NVIDIA was proud to introduce programmable shading with Cg, which supported dozens of different OpenGL and DirectX profile targets. It allowed developers to incorporate interactive effects within 3D applications and share them among other Cg applications, across graphics APIs, and most operating systems (Windows XP, Vista and Windows 7, Mac OS X for Leopard, Snow Leopard & Lion, Linux 32-bit & 64-bit) as well as balance effect complexities with client GPU capabilities.
Going forward, we recommend new development with GLSL, or HLSL for Windows applications, rather than Cg.
What is Cg?
C for Graphics. Cg is the high-level GPU shader authoring language designed, developed and implemented by NVIDIA.
Is Cg Proprietary?
The Cg Language Specification is published and open in the sense that other vendors may implement products based on it.
Does Cg replace OpenGL or Direct3D?
Cg layers on top of OpenGL, DirectX 9, 10 or 11.
The Cg compiler outputs assembly, GLSL or HLSL code in various formats supported by OpenGL or DirectX.
Does Cg replace C/C++?
Cg is a GPU shading language. A shading language is a type of programming language that tells the GPU how to shade pixels. The main program will still be written in C, C++, C#, Java, Python or other CPU programming language.
What's the difference between the Cg language and a Cg compiler?
The Cg language has a syntax and grammar suitable for real-time programmable GPUs.

A Cg compiler is an application that accepts Cg language input, and produces output in one of the assembly language, GLSL or HLSL formats that are accepted by modern GPUs.
Platforms
What platforms are supported by the NVIDIA Cg Toolkit?
- Windows 32-bit, 64-bit
- Linux 32-bit, 64-bit
- Mac OS X ppc, i386 and x86_64
- Solaris 32-bit, 64-bit
What is NVIDIA providing to developers?
![Nvidia Nvidia](/uploads/1/2/6/6/126698586/234959536.jpg)
NVIDIA provides developers with the NVIDIA Cg Toolkit, comprising of:
- Compiler
- Runtime Libraries
- Language Specification
- Standard Library
- Reference Manual
- User's Manual
- Example programs, shaders and effects for OpenGL and Direct3D
Does the Cg Compiler perform platform specific optimizations?
Yes, the NVIDIA Cg Compiler aggressively optimizes shaders for multiple target GPU architectures.
