Develop high-performance, photorealistic, extensible, and cost-effective visualization applications through open source libraries.


Deliver high-performance, high-fidelity visualization solutions and applications efficiently with open source libraries in the Intel® oneAPI Rendering Toolkit, optimized for Intel® Xeon® Scalable processors.

Why Use Intel® oneAPI Rendering?

It offers a flexible platform as an alternative to dedicated graphics accelerators that reduces coding complexity, I/O constraints, and limited memory while broadening support for third-party plug-ins.

More than 100 independent software vendors (ISV) use these libraries, which include the following:

  • Intel® Embree, a highly optimized, ray tracing kernel library and low-level API for acceleration structures and ray and geometry intersections, which is broadly adopted throughout the professional rendering market.
  • Intel® OSPRay, a cluster-capable, scalable, extendable, ray-tracing, rendering toolkit that includes path tracing and volume rendering. It efficiently uses threading and vectorization to create interactive, high-fidelity applications on CPUs from Intel.
  • Intel® OpenSWR, an OpenGL* low-level rasterization library upstreamed to the Mesa OpenGL open source project to achieve high rendering performance when GPUs are unavailable or are too limiting. Completely CPU-based and built on top of LLVM, this library provides performance advantages over Mesa llvmpipe renderers.
  • Intel® Open Image Denoise, a library of image denoising and filtering algorithms to improve visual quality and reduce rendering times.
  • Intel® Open Volume Kernel Library, a highly optimized library of impactful, low-level volumetric data-processing algorithms to enable rendering and simulation processing of 3D spatial data. (Available in Q4 of 2019.)

Intel oneAPI Rendering Toolkit is an approach for supporting big data use on platforms of all sizes, including workstations, data centers, the cloud, and high-performance computing (HPC) clusters. This is achieved by enabling the parallelism and performance already in your Intel® platforms without the memory limits and cost of dedicated GPU-based solutions.

To make it even easier to use this ground-breaking visual technology, Intel collaborated with hardware and software providers to design Intel® Select Solutions for Professional Visualization. These turnkey solutions provide an out-of-the-box experience for combining computationally intense codes with photorealistic rendering and visual analysis tools used in science, manufacturing, professional rendering, architecture, gaming, and more.

This is a high-performance, scalable software rasterizer in the Mesa open source community project that's compatible with OpenGL*. Use unmodified visualization software to work with datasets when GPU hardware is unavailable or is limiting. This CPU-based product runs on laptops, workstations, and compute nodes in high-performance computing (HPC) systems.

This high-performance, open source library improves visual quality during interaction by using machine learning methods (includes Intel® Math Kernel Library for Deep Neural Networks functions) to selectively filter noise. This independent component can be used for noise reduction on 3D rendered images, with or without Intel Embree.
