Iray for Rhino

NVIDIA® IRAY® is a highly interactive and intuitive physically based rendering technology that generates photorealistic imagery by simulating the physical behaviour of light and materials. Unlike traditional production renderers, Iray delivers results reflecting real-world behaviours. Designers don't need expert knowledge of computer graphics techniques to quickly achieve photorealistic results. 

Iray progressively refines its image until completion, providing consistent results from interactive editing to final frame. It's a highly predictive approach that marries with the scalable, world-class performance across NVIDIA GPUs to give constant feedback and rapid results. This slashes the time needed to perfect scenes and deliver images rivaling photographs. 
 
The Iray for Rhino plugin offers Rhino3d designers a quick rendering solution to produce physically based, photorealistic visualisations. Iray is integrated into Rhino, rendering directly within its viewports to give you continual, realistic feedback as you craft your model's form, materials, and lighting. Iray's physically based capability predicts the behaviour of real-world materials and lights, giving you accurate results with minimum setup or specialized knowledge. The NVIDIA vMaterials Library is supported as well as material exchange capabilities with other MDL compatible applications.
 
Who is Iray for? Iray is primarily for designers and visual effects artists working with 3D content who require predictable photorealistic imagery. It delivers immediate visual feedback that results in stunning imagery for everything from architecture, engineering, and design to marketing and advertising visual effects.

Key Features

 

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—such as cut-outs, displacements, or bump maps—that are commonly not modeled in the primary geometric description. 

New in Iray 2015 is support for measured materials using the X-Rite Appearance exchange Format (AxF). Plus, it offers the MDL's fully programmable support for procedurally generated textures and functions with full GPU acceleration.

Interactive 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) that are 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 using standard imaging or compositing software.

Other Features of Iray
  • Instancing
  • Motion Blur
  • Caustics
  • Luminance Distributions
  • Light Updates For Cross Sesction Planes
  • Deca/Sticker Material Element
  • Sub-Surface Scattering
  • Depth Of Field
  • Volumetrics

 

Technical Details

 

Technical Details / System Requirements:

Software
  • McNeel Rhinoceros 5
  • 64-bit-Windows
Hardware

Iray for Rhino functions on any system certified to operate McNeel Rhinoceros. Rendering speed is increased with faster CPU and GPUs, more CPU and GPU cores, and especially with NVIDIA GPUs. Most NVIDIA products from the past 5 years (using the Fermi, Kepler, or Maxwell architecture) are supported. Iray for Rhino scales very efficiently across all processors within the system and provides control over which processors are used.
