Intel® oneAPI Rendering Toolkit

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.

Photorealistic Rendering That Scales

The Intel® oneAPI Rendering Toolkit is designed to accelerate these types of workloads with a set of rendering and ray tracing libraries to create high-performance, high-fidelity visual experiences. With the libraries, get the most from powerful Intel® hardware by optimizing CPU and future Xe or GPU rendering performance at any scale. Creators, scientists, and engineers can push the boundaries of visualization by using the toolkit to develop amazing studio animation and visual effects or to create scientific and industrial visualizations.

Applications include:
Digital content creation
Professional rendering
Computer-aided design, architectural engineering
Scientific visualization
Gaming VR and AR

The libraries and advanced components of the Render Kit are industry-trusted building blocks, which are integrated into many third-party professional content creation tools and applications for broader ecosystem use. These building blocks include, but are not limited to, V-Ray and Corona Renderer (Chaos Group), Paraview (Kitware), Cinema4D (Maxon), AutoCAD, 3DSMax, Revit (Autodesk) Dreamwork’s Moonray Renderer, Framestore Freak Renderer and EA Frostbite Game Engine.

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® OSPRay

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

Intel® Open Volume Kernel Library

Enable rendering and simulation processing of 3D spatial data with low-level volumetric data-processing algorithms.

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
