Nvidia Iray Rendering Your Reality NVIDIA® IRAY® is a highly interactive and intuitive physically based rendering technology that generates photorealistic imagery by simulating the physical behavior of light and materials. Its highly predictive approach, combined with its scalability, delivers world-class performance on NVIDIA GPUs for constant feedback and rapid results. This slashes the time needed to perfect scenes and delivers images rivaling photographs. Iray is primarily for product, building and lighting designers, and digital photographers who work with 3D content, requiring predictable photorealistic imagery. NVIDIA IRAY FEATURES NVIDIA continually evolves Iray's feature set to improve the physically based 3D and VR rendering workflows of designers and digital artists. IRAY WITH AI Iray with AI is bringing the power of deep learning to both final frame and interactive photorealistic rendering. This unique capability coming to Iray will enable the completion of final images many times faster and can be used to make interactive rendering many times smoother for a far more rapid understanding of your scene’s composition and lighting during editing. Learn More IRAY AND VR VR support within Iray ranges from panoramic snapshots to fully immersive Iray VR experiences. VR snapshots are created with spherical lenses that are actually just one of the many new physical and industry lenses available to use from any Iray camera location. Iray VR produces an immersive photorealistic world that you can walk about using a head-mounted display (HMD) to examine your scene from every vantage point. PHYSICALLY BASED LIGHTING Iray is a high-performance, global illumination rendering technology that generates imagery by simulating the physical behavior of light interaction with surfaces and volumes. Images are progressively refined to provide full global illumination—including caustics, sun studies, and luminance distributions. PHYSICALLY BASED MATERIALS NVIDIA Material Definition Language (MDL) defines the properties of materials for Iray. These range from the color of surfaces to their reflection or refraction properties, light emission of surfaces, and scattering and absorption properties of volumes. They even include additional geometric properties of surfaces—like cut-outs, displacements, or bump maps—that are commonly not modeled in the primary geometric description. Learn More INTERACTIVE 3D RENDERING Iray is built for interactivity and delivers immediate visual feedback throughout the entire design process. The Iray interactive rendering mode uses advanced approximation algorithms to mimic realism while minimizing unwanted noise. This maximizes performance during interaction. LIGHT PATH EXPRESSIONS Iray offers compositing elements that isolate lighting components, using a technique called Light Path Expressions (LPE) rendered in parallel and saved to output buffers. LPEs can be defined on a per object and per light basis, allowing for complete creative control in post processing using standard imaging or compositing software.
