In this tutorial, Jeff Patton will make us understand why we should use iray and what are the advantages of using it.
What is iray:
iray is an intuitive to operate, interactive, consistent, high-performance global illumination rendering technology that generates photorealistic imagery by simulating the physical behavior of light. Unlike current ray-tracing renderers, iray does not depend on complex renderer specific shaders and settings to approximate global illumination.
iray achieves its high level of performance by taking full advantage of the CUDA programming model, allowing interactive previewing on a single NVIDIA GPU, and scaling almost linearly on NVIDIA multi-GPU platforms.
iray balances intuitive ease of use and scene setup with the highest quality photorealistic final frame output and interactive performance.
