A critical companion to NVIDIA’s recently announced GeForce™ FX GPU family, the Cg language is a C-like high level graphics programming language that, when combined with a modern GPU such as NVIDIA’s GeForce™ FX, allows 3D content developers to create cinematic-caliber, real-time worlds and characters. The combination of a simple-to-use programming language and the cinematic computing platform will allow developers to create real-time graphics content that is similar to film quality rendering.
The NVIDIA Cg Compiler and other elements of the Cg programming environment, including the open source code, are available today for free at http://developer.nvidia.com and www.cgshaders.org.
The Cg tool kit provides a turnkey solution that significantly speeds up development time. Yeti Studios, a game development house based in the United Kingdom, is taking advantage of Cg to bring Gun Metal to the PC platform. “Cg provides us with a huge advantage, as it allows us to write code once and compile it anywhere,” commented Phil Wilson, development director for Yeti Studios, the creators of Gun Metal. “We had a very specific design vision for Gun Metal and Cg has allowed us to turn our vision into a vivid reality. We’ve taken full advantage of the NVIDIA hardware advancements and new software tools, such as DirectX 9.0, to propel gamers into the intricately detailed Gun Metal world for a gaming experience they won’t soon forget.”
NDL, makers of a 3D graphics engine used to propel games including “Dark Age of Camelot: Shrouded Isles” and “The Elder Scrolls III: Tribunal,” are taking advantage of Cg to provide 3D artists with more control. “NDL’s goal to make it as easy as possible for game developers to immediately use pixel and vertex shader code,” said John Austin, president of NDL. “Our next release will include the capability to directly read in CgFX files, preview exactly how the effect will look in the game, and allow the artist to tweak all of the necessary parameters without ever leaving their art tool, and without the need for a programmer. Game developers will have an unprecedented degree of flexibility and control over the graphics in their games.”
“All the pieces for cinematic computing are finally coming in to play, in a very attainable way,” said Ned Finkle, vice president of strategic marketing at NVIDIA. “We’ve seen tremendous support from both the DCC and game development communities since Cg was introduced, with Cg plug-ins being introduced and games, such as Gun Metal, reaching new levels of visual quality. With the availability of new APIs, and soon GeForce FX, it will be exciting to watch developers use these tools to take us into a new era of cinematic computing.”
