Introduced with OptiX 5.0, the AI-Accelerated Denoiser is a new post-processing feature to denoise images reducing the need for rendering iterations. This denoiser is 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.
From film and games to design and scientific visualization, OptiX has been successfully deployed in a broad range of commercial applications. These applications range from rendering software to scientific visualization (including Gordon Bell Award finalists), defense applications, audio synthesis, and computing lightmaps for games.
