Intel® oneAPI Rendering Toolkit

Powerful Libraries for High-Fidelity Rendering and Visualization Applications

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.

Award recipients: Sven Woop, Carsten Benthin, Attila Afra, Manfred Ernst, and Ingo Wald

Visual expression is an integral part of our digital world. More accurate, more realistic, and richer imagery that is better aligned with the human visual system has proven beneficial across a diverse set of uses and industries. For example, imagery in medical research, geophysical exploration, motion pictures, product design, and cosmology can be quickly rendered into rich, realistic visuals.

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® Open Image Denoise

Improve 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 OpenGL-compatible software rasterizer 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

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® OSPRay

Use this ray-tracing API and engine to rapidly develop interactive, high-fidelity, visualization applications.

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

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.

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.
