Nvidia’s Gameworks tool has been expanded to incorporate ray tracing

For the uninitiated, ray tracing is a rendering technique used to generate an image by tracing the path of light as pixels in an image plane and simulating the effects area shadows, surface reflections, as well as ambient occlusion on virtual objects. For many years, ray tracing has been standard technology in the film industry, where visual effects artists can take hours and hours to render a single frame of, say, a TIE fighter blowing up in a Star Wars movie.

Among the game engines that now support the DXR API are Unreal Engine 4, Unity, Frostbite and Northlight.

Game Developers Conference 2018 is going on right now and many companies are bringing new technologies and applications to show off, including NVIDIA.

'Real-time ray tracing has been a dream of the graphics industry and game developers for decades, and Nvidia RTX is bringing it to life, ' said Tony Tamasi, senior vice president of content and technology at Nvidia. "GPUs are only now becoming powerful enough to deliver real-time ray tracing for gaming applications, and will usher in a new era of next-generation visuals".

Some companies have already been experimenting with the tools, but until NVIDIA announces and releases their Volta GPU line, we'll only be able to see the results of their real time ray tracing tech in videos rather than in action n on our own monitors.

Remedy also had a talk at GDC today about incorporating DXR into their Northlight engine. Gamers are in for something special'.
