Published by Intel a completely free and accessible library for RayTracing that can be downloaded from GitHub.
The new RayTracing technology is on everyone's lips and has, at the moment, more detractors than followers. This is due to NVIDIA's decision to release the Turing architecture GeForce RTX one year in advance. Despite all this, this technology is here to stay and so Intel believes. The largest processor company has launched a free library called Open Image Denoise (OIDN) developed especially for RayTracing.
Intel launches free library for RayTracing
This new library comes under an Apache 2.0 license. The OIDN library is based in part on the Intel Rendering Frameworks. It has been specially developed to optimize the use of processor resources. Offers scaling of the number of cores available within the CPU. We can run this library on any x64 CPU that has compatibility with SSE 4.2 instructions. Something very interesting is that it allows the use of AVX2 and AVX-512 instructions supported by the latest Xeon and Core X, which allows for a significant improvement in results.
As an alternative we have the Denoiser AI from NVIDIA, which has relatively similar characteristics but is paid. NVIDIA's solution relies on a combination of deep learning and GPU computing to deliver good results. Clearly, Intel's solution, being free, is more accessible and for experimentation it may even be a better solution.
We can download OIDN from the Intel repository on GitHub.
