What's Included
Intel® Embree
Improve the performance of photo-realistic 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® ISPC
Compile using a variant of the C programming language with extensions for SPMD programming for fastest rendering performance.
Intel® Open Image Denoise
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® OpenSWR
Use this software rasterizer that's compatible with OpenGL* to work with datasets when GPU hardware isn’t available or is limiting. This CPU-based product runs on laptops, workstations, and compute nodes in high-performance computing (HPC) systems.
Note Intel® OpenSWR is available as part of the Mesa OpenGL open-source community project at www.mesa3d.org.
Intel® Open Volume Kernel Library (Intel® Open VKL)
Enable rendering and simulation processing of 3D spatial data with low-level volumetric data-processing algorithms.
Develop interactive, high-fidelity, visualization applications using this ray-tracing API and engine.
Intel® OSPRay for Hydra*
Connect the Intel oneAPI Rendering Toolkit 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.
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.
Rendering Toolkit Utilities
The included Render Kit Superbuild utility automatically downloads the Intel oneAPI Rendering Toolkit source code, TBB binaries, Intel® Implicit SPMD Program Compiler (Intel® ISPC) binaries, and build binaries for each component.
The Academy of Motion Picture Arts & Sciences, which presents the annual Academy Awards*, awarded Intel® Embree Ray Tracing library, a component in the Intel® oneAPI Rendering Toolkit, a Scientific & Technical Achievement Award in 2021. The award recognized Intel® Embree for its geometric rendering in contributing innovation in significant and lasting ways to the movie-making process.

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 oneAPI 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
