NVIDIA IRAY

Rendering Your Reality

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.

Bistro Iray with AI for interactive photorealistic rendering

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.

Iray and VR produces an immersive photorealistic world

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.

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.

MULTIPLE GPUS IN ONE MACHINE

Iray supports any number or combination of GPUs and CPUs running within the same machine and gives you control over which are being used for rendering. This makes multi-GPU systems the preferred choice for Iray applications.
