Nvidia wows the crowd with Iray, a turnkey rendering solution for 3-D graphics application developers built by its subsidiary Mental Images. Here, Iray is used to stream a hosted, photorealistic mock-up of an office space over the Web as an example of a cloud computing application that architects and designers could use to show clients their work. Iray creates "beautiful images" that can't be distinguished from photographs, said Jen-Hsun Huang, while Nvidia graphics horsepower allows new image views to be rendered in mere seconds.
