Intel bulks up the open-source ray tracing engine


ntel has released version 2.0 of the open source OSPRay ray-tracing engine and comes with various improvements, Phoronix found out.

Intel describes OSPRay as an open, scalable, and portable (OSP) ray tracing engine for CPU rendering, geared towards scientific visualization applications. It supports ambient occlusion, shadows, global illumination with physically-based materials and volume rendering, and it can be run on large, distributed-memory systems. OSPRay also supports the latest AVX-512 instruction set and is part of Intel’s oneAPI programming model.

The patch notes detail that version 2.0 brings API-breaking improvements, but comes with an API migration library. It further uses the Intel Open Volume Kernel Library (Open VKL) for “greatly enhanced volume sampling and rendering features and performance.” Version 2.0 also supports Intel’s Open Image Denoise and uses the latest Intel version of Embree, Intel's collection of high-performance ray tracing kernels.

All details are on OSPRay’s GitHub page.
