Graphics developers routinely face a trade-off when using ray tracing to create realistic, immersive experiences. They either allow for the hours (and hours) it takes to render high-quality images or use denoising methods to produce less than high-quality images, but do it a lot faster.

Intel® Open Image Denoise can remove this dilemma.

It’s an open-source library of high-performance, high-quality, machine-learning-based denoising filters for images rendered with ray tracing. As part of the Intel® oneAPI Rendering Toolkit, this library is suitable for both interactive and final-frame rendering, runs on almost any Intel® CPU, and significantly reduces rendering times.

It’s also completely free.

Join graphics software engineer Attila Afra for a detailed session that includes:

  • The importance and impact of denoising when rendering images with ray tracing
  • How Intel Open Image Denoise achieves high-quality denoising using machine learning (hint: it filters out the Monte Carlo noise)
  • How to use the simple, flexible C and C++ API to integrate denoising into existing renderers in hours or even minutes
  • Training the denoising neural networks yourself to achieve even higher quality for your renderer or implement custom filters
