Nvidia Iray

Simulate Your Reality

NVIDIA® Iray® is an intuitive physically based rendering technology that generates photorealistic imagery for interactive and batch rendering workflows. Leveraging AI denoising, CUDA®, NVIDIA OptiX, and Material Definition Language (MDL), Iray delivers world-class performance and impeccable visuals—in record time—when paired with the newest NVIDIA RTX-based hardware.

Using the Latest NVIDIA Technology

The latest version of Iray adds support for RTX, which includes dedicated ray-tracing-acceleration hardware support (RT Cores) and an advanced acceleration structure to enable real-time ray tracing in your graphics applications.

SOLIDWORKS Visualize render


In the 2019 release of the Iray SDK, all render modes utilize NVIDIA RTX technology. In combination with AI denoising, this enables you to create photorealistic rendering in seconds instead of minutes.

AI Denoising

Using Tensor Cores on the newest NVIDIA hardware brings the power of deep learning to both final-frame and interactive photorealistic renderings. This unique capability speeds the completion of final images and smooths interactive rendering for a more rapid understanding of your scene’s composition and lighting.

NVIDIA Material Definition Language

NVIDIA Material Definition Language (MDL) defines the properties of materials, ranging from the color of surfaces to their reflection or refraction properties to the light emission of surfaces. They even include additional surface geometric properties that are not commonly modeled in the primary geometric description of surfaces, such as cut-outs, displacements, or bump maps.

Multi-GPU and Multi-Machine Setup

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