OptiX 5.0 introduces an AI-accelerated denoiser based on a paper published by NVIDIA research "Interactive Reconstruction of Monte Carlo Image Sequences using a Recurrent Denoising Autoencoder". It uses GPU-accelerated artificial intelligence to dramatically reduce the time to render a high fidelity image that is visually noiseless. This provides ultra-fast interactive feedback to artists, allowing them to iterate their creative decisions more quickly and achieve their final product much faster.
The AI-accelerated denoiser was trained using tens of thousands of images rendered from one thousand 3D scenes. The training data was given to an auto encoder similar to the one described in the paper and run on an NVIDIA® DGX-1™. The result is an AI-accelerated denoiser which is included in the OptiX 5.0 SDK that works on a wide number of scenes. To further expand quality and performance, developers can train their own denoiser neural network using images produced by their renderer.

Our very first integration tests revealed right from the start that NVIDIA has created an exceptional piece of software engineering by combining the power of AI and their powerful GPU hardware to surmount what has bothered every single GPU software developer for years - Noise in the image. The use of AI Neuronal Network technology in OptiX 5.0 to enhance the process of denoising and cebas' engineering work on finalRender's trueHybrid™ technology offers a bright future towards higher quality photo-realistic images in much lesser time.Edwin Braun, CEO & Co-founder, cebas Visual Technology

We’re finding the NVIDIA denoising results to be very impressive on interactive scenes, giving artists a much quicker estimate of what their final result will look like. We believe this will speed the creative process while using our upcoming V-Ray GPU.Vlado Koylazov, founder, Chaos Group
Founded by animation industry veterans, Isotropix™ is a start-up specialized in developing high-end professional graphics software and aims at providing CG artists game-changing innovations.
Thanks to its AI-driven denoising capability, OptiX 5.0 accelerates the Clarisse path tracer up to eight times! Combined with TITAN V, it will be a game changer for artists as they can make instant creative decisions on images that are very close to final renders — all from their PC.Sam Assadian, CEO and co-founder, Isotropix

It was staggering to witness OptiX 5.0’s ability to create clean images that are genuinely representative of the final frame. As Clarisse continues to refine the render, the denoiser converges on the final clean result in a smooth, deterministic way, meaning that artists are able to make detailed artistic lighting decisions considerably faster than they could before.Graham Jack, chief technology officer, Double Negative
Redshift Rendering Technologies Inc was founded in early 2012 in Newport Beach, California with the goal of developing a production-quality, GPU-accelerated renderer with support for the biased global illumination techniques that until now have remained squarely in the CPU-only domain.
