 Cg Toolkit 2.1, November 2008 Release

Cg: C for Graphics for DirectX and OpenGL, PC and ConsolesIntroduction

The award-winning Cg Toolkit provides a compiler for the Cg 2.1 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 2.1 allows you to incorporate stunning interactive effects into your 3D applications.

The components of the Cg Toolkit include:

  • durer.cgfx from the NVIDIA Shader LibraryNVIDIA Cg Compiler Release 2.1
  • 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 2.1 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 November 2008 version of Cg 2.1 corrects several issues found in the prior release:

  • Fixed crash when cgGL routines were called without a current GL context
  • Fixed a bug in compiling CgFX files with multiple geometry shaders
  • Fixed D3D10 runtime's handling of the parameter buffer (cbuffer)
  • D3D10 runtime now correctly deals with true integer parameters
  • Shared parameter arrays were not being updated correctly
  • Resolved an issue with changing the variability of matrices to CG_LITERAL

The 2.1 release of Cg introduces several new features and improvements:

  • New Direct3D 10 profiles (vs_4_0 and ps_4_0) to cross-translate Cg to HLSL10
  • New Runtime library for Direct3D 10
  • Virtual file system for including source during shader compilation
  • Improvements to the GLSL translation profile
  • Documentation updates for all new API and features
  • New examples demonstrating Direct3D10 usage and more
  • Runtime performance improvements and bug fixes
  • Compatibility with Cg 2.0

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