Nvidia Demonstrates Interactive Ray-tracing

Nvidia demonstrated the new release of the Application Acceleration Engine, AXE 2.0. The new version is optimized to run on the new Quadro Fermi cards, but will run on any G92 or later generation cards. These engines allow for interactive ray-tracing where the user can interact with the ray-traced scene quickly without an extensive wait for re-rendering.

Nvidia’s 'mental images' division also demonstrated its iRay application, which takes the above capabilities and adds physically correct global illumination to the features. Global illumination is critical for correct lighting in most 3D digital content creation and the ability to view and interact with a globally illuminated scene will greatly accelerate the ability of artists to work quickly. In addition iRay supports network distributed rendering across GPUs.

Nvidia partners like The Foundry, RTT, and Bunkspeed also demonstrated their applications making use of CUDA-accelerated interactive ray-tracing. RTT’s application actually calculated airflow over the model and rendered the model, interactively, both using CUDA, while Bunkspeed’s SHOT uses mental images' iRay to provide interative ray tracing and global illumination.

In a few GPU generations, these can be expected to proceed from ‘interactive’ to ‘real-time’ and we should start seeing the use of real-time ray-tracing and global illumination in games.

    Rendering scenes using ray-tracing and global illumination takes freakin FOREVER, even on the i7 based workstations at school. I'm amazed at how quickly you're able to preview a scene using the hardware acceleration provided by Nvidia's latest generation of GPU's. It's literally just a matter of seconds based on the videos I've seen.

    This really does make "interactive" ray-tracing possible for the first time on a desktop... awesome. This is the sort of application the Fermi architecture really excels at. The emphasis Nvidia places on this market is probably the main reason I'll be going with a Fermi based solution for my next build, and not an Evergreen.

    I remember back in the day (late 80's) when Amiga had it's big hay day with ray tracing, there were pundits that said that real time ray tracing would never be a reality. This was back when a single frame would take days to render in a farm. Oh how far we have come.

    So were probably less the 10 years off from being able to have games based on real time ray tracing, this makes me happy for some reason.

    Yeah i was amazed at the viper pic, sooo realistic!
