What's Included
Intel® Embree
(Includes support for Intel GPUs.)
Improve the performance of photorealistic rendering applications with this library of ray tracing kernels. The kernels are optimized for the latest Intel processors with support for Intel® Streaming SIMD Extensions [4.2] through to the latest Intel® Advanced Vector Extensions 512.
Intel® Implicit SPMD Program Compiler (Intel® ISPC)
Compile using a variant of the C programming language with extensions for SPMD programming for the fastest rendering performance.
Intel® Open Image Denoise
(Includes support for Intel and third-party GPUs.)
Increase image quality with machine learning algorithms that selectively filter visual noise. This independent component can be used for noise reduction on 3D rendered images, with or without Intel Embree.
Intel® Open Volume Kernel Library (Intel® Open VKL)
Enable rendering and simulation processing of 3D spatial data with low-level volumetric data-processing algorithms.
Intel® Open Path Guiding Library (Intel® Open PGL)
Increase rendering performance by improving the sampling quality of complex light transport effects. Facilitate state-of-the-art path-guiding algorithms into your renderer.
Intel® OSPRay
Develop interactive, high-fidelity visualization applications using this rendering API and ray tracing engine.
Intel® OSPRay Studio
Perform high-fidelity, ray traced, interactive, and real-time rendering through a graphical user interface with this new scene graph application addition to Intel OSPRay.
Intel® OSPRay for Hydra* (Open Source GitHub*)
Connect the Render Kit libraries in your application to the universal scene description (USD) Hydra rendering subsystem by using the Intel® OSPRay for Hydra* plug-in. This plug-in enables fast preview exploration for compositing and animation, as well as high-quality, physically based photorealistic rendering of USD content.
Rendering Toolkit Utilities
The included Render Kit Superbuild utility automatically downloads the Render Kit source code, Intel® oneAPI Threading Building Blocks (oneTBB) binaries, Intel ISPC binaries, and build binaries for each component.
What Customers Are Saying
“An example of this adoption of technology from Intel was Tangent’s incorporation of Embree, Intel’s open source ray tracing core. This had a very dramatic, positive impact on production of Next Gen, resulting in performance figures such as a 10 to 15 overall decrease in render time, with greater decreases witnessed on scenes with heavy volumetrics and motion blur [and] 400 to 500 decrease on frames that exhibited extreme motion blur.”
– Jeff Bell, president, Tangent Studios
“We found Intel Embree ray tracing kernels to be the best efficient alternative to our legacy code to improve the performance. This drastically improved multithreaded and vectorization capabilities that reduced our rendering time helping Illumination Mac Guff and increased the quality and richness of our images.”
– Xavier Bec, head of research and development, Illumination Animation
“By working with Intel on the Intel Rendering Toolkit, we’ve been able to leverage and take advantage of its open source platform. This has meant we have been able to rapidly research and develop proof of concepts that focus on cost-efficient methods for the creation [of] rendered images and user experiences for the future.”
– Paul Chapman, virtual media manager, Bentley Motors Limited
"V-Ray* is the industry’s gold standard for ray traced rendering and Intel has been there for us from the beginning with high-performance multicore processors and optimization software. We’re now delivering on-demand rendering with Chaos Cloud where Intel continues to provide the scalability that we count on."
— Phillip Miller, vice president of product management, Chaos Group
"On the recently released Modo* 14.1, our customers are reporting amazing rendering performance with Intel Embree ray tracing library and Intel Open Image Denoise that previously would have only been available through high-end GPUs. This really packs a one-two punch to those costly render times on CPU hardware that all our users can appreciate."
– Shane Griffith, director of product-digital design, Foundry
"KeyShot integrates Intel Open Image Denoise for one-click, high-performance image denoising with results that are simply incredible. Through this technology, KeyShot's reputation for speed and quality is complemented with a level of noise reduction and feature preservation that aids the visualization process and accelerates the product delivery cycle.”
– Derek Cicero, Vice President of Products, Luxion (Makers of KeyShot)
"Visualization is the key to better simulations. So, by visualizing the data in real time, we get faster development timescales, as well as much better insight."
— Dr. Paul Shellard, professor of cosmology and director of the Stephen Hawking Centre for Theoretical Cosmology at the University of Cambridge
"Atipa and Intel’s infrastructure make it possible to train the next generation of visualization experts with advanced tools and [the] software infrastructure they will encounter in most advanced industry settings."
— Michael E. Papka, professor of computer science, Northern Illinois University (NIU)
“TACC applauds the Intel Rendering Toolkit and our long standing collaboration to help us deliver Professional Visualization that enables the wide availability of high fidelity and interactive visualization for many more users."
