Announcement: https://www.linkedin.com/pulse/advanced-ray-tracing-apis-proposed-oneapi-jim-jeffers/

Published at https://spec.oneapi.com/oneart/latest/index.html

• Advanced ray tracing capabilities have been added to the oneAPI specification providing software developers across the industry the ability to “write once” for high-fidelity ray-traced computations across multiple vendors’ systems and accelerators. Standardizing these interfaces provides well-designed, tried and true APIs and options for a broad set of compute and rendering infrastructure development.

• The advanced ray tracing functionality is subdivided into several domains within the oneAPI Specification:

  • Geometric ray tracing computations
  • Volumetric computation and rendering
  • Image denoising
  • Scalable rendering and visualization infrastructure

• The set of Advanced Ray Tracing APIs include the following, which are in active use via the Intel® oneAPI Rendering Toolkit:

  • Embree
  • Open Volume Kernel Library
  • Open Image Denoise
  • OSPRay

• oneCCL

  • Minor API corrections

• oneDAL

  • Correct version MACRO definition
