Cg 1.5 Beta 2
Quick Links
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 Beta 2
• Unified Cg/CgFX Runtime
• Cg User's Manual
• Cg Language Specification
We hope that you will enjoy the exciting world of Cg programming.
Latest Cg Toolkit Features
This 1.5 Beta 2 release of Cg introduces several new features:
• New Cg runtime API for procedural effects creation (effect annotations, index state assignments)
• Solaris x86 support
• Mac OS X: Universal or so-called "fat" binaries with both PowerPC and x86 code
• Documentation updates, including Cg Standard Library and standard CgFX states
• New examples: 15 OpenGL-based demos from The Cg Tutorial, 7 Direct3D9-based demos, and 3 advanced OpenGL demos
• Improved DirectX support for state assignments for CgFX files
• Fixes reported Cg 1.4 compatibility problems
• Bug fixes: memory leaks fixed, fixed mis-interaction between array resizing and compiler-generated constants
• Runtime now supports loading pre-compiled objects through runtime API (CG_OBJECT for cgCreateProgram)
The prior Beta 1 introduced the following:
• OpenGL GLSL profiles
• Direct3D9 SM3.0 profiles
• Procedural API for Effect creation (COLLADA support)
• Program combining for inter-program optimization
• Rewrite of major portions of the Cg Runtime for enhanced performance
• Cg 1.5 Beta 1 now ships with native implementations for Win32, Win64, Linux (32-bit and 64-bit), MacOS 10.3 (Panther) and 10.4 (Tiger).
• Cg 1.3 and 1.4 style Effects files supported
• Cg 1.5 Beta 1 should be backward compatible with apps written against Cg 1.4.1.
