iray® is the world’s first GPU accelerated and physically correct, photo-realistic rendering solution. When combined with the parallel processing power of the latest NVIDIA® GPUs, iray achieves interactive speeds that dramatically reduce the iterative creative process of perfecting a scene. Unlike most production renderers, iray delivers results that reflect real-world behaviors, liberating designers from needing expert knowledge of computer graphics techniques to achieve photo-realistic results.

The iray “push-button” rendering approach marries ease of use during scene setup with the highest quality photorealistic final frame output and interactive performance. iray also progressively refines the image until maximum fine detail is reached, providing a single process which combines interactive pre-visualization and final frame rendering.

iray takes full advantage of the CUDA™ programming model, allowing interactive previewing on both single and multiple NVIDIA GPU systems.

Software developers can license the iray Integration Framework to add iray rendering technology into their own products and custom solutions. Using the framework API, developers can easily integrate iray into a wide range of applications that benefit from physically correct and interactive renderings, including architectural design, product visualization, product marketing, automotive design and styling.
