Introduction

The Cg Toolkit provides a compiler for the Cg language, runtime libraries for use with both leading graphics APIs, runtime libraries for CgFX, example applications, and extensive documentation. Supporting over 24 different OpenGL and DirectX profile targets, Cg will allow you to incorporate stunning interactive effects into your 3D applications. The components include:

• NVIDIA Cg Compiler Release 1.5
• Unified Cg/CgFX Runtime
• Cg User's Manual
• Cg Language Specification
• Example programs and shaders

We hope that you will enjoy the exciting world of Cg programming.

Latest Cg Toolkit Features

Release 1.5 of Cg introduces several new features:

• OpenGL GLSL profiles
• Direct3D9 SM3.0 profiles
• Procedural API for creating effects (COLLADA support)
• New API for combining programs from multiple domains
• Improved DirectX support for CgFX files
• Multithread safe Runtime
• Universal binaries for Mac OS X 10.4 (Tiger) with support for both PPC and x86
• Support for Solaris10 on x86
• Improved documentation, including Cg Standard Library and standard CgFX states
• New OpenGL and Direct3D9 examples
• Supports loading pre-compiled objects (CG_OBJECT in cgCreateProgram)
• Enhanced runtime and compiler performance

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

Cg 1.5 ships with native implementations for Win32, Win64, Linux (32-bit and 64-bit), MacOS 10.3 (Panther), MacOS 10.4 (Tiger), and Solaris10 x86.

Cg 1.5 should be backward compatible with apps written against Cg 1.4.1.
