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.
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.
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.
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 (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.
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.
NVIDIA is continually evolving the Iray feature set to improve the physically based 3D and VR rendering workflows of designers and digital artists.
Separation of different types of light paths into different frame buffers.
Realistic, physically-based lighting model which produces desirable effects, such as soft shadows; simple and natural to set up.
Render color coded image to determine luminance.
Rendering algorithms which can simulate very complex light paths, such as those which create caustics.
Full spectral rendering including lights, textures and output.
Render any OpenVDB file created in 3rd party applications.
Easy drop in usage of measured materials via MDL.
Realistic lighting based on measured data.
Memory savings, and immediate updates of animated objects.
Show highlights even if chamfers or filets are not explicitly modelled.
Multiple cross section planes, optionally closed with caps.
Place multiple double sided stickers on objects.
Efficient implementation of depth-of-field, optimized for each rendering mode.
Provides an idea of motion in still images, and of fluidity in rendered animations.
Separate camera settings for right and left eye to achieve a 3D stereo output.
Render out cylindrical or spherical maps.
