Systems and methods for graphics rendering based on machine learning

Abstract

Embodiments described herein pertain to a machine-learning approach for shading. A system may determine, for each of a plurality of pixels, object visibility information based on one or more objects in a virtual environment. The system may select, for each pixel, a light source from a plurality of light sources in the virtual environment. The system may determine, for each pixel, lighting information associated with the light source selected for that pixel based on the associated object visibility information. The system may generate a first latent representation of the lighting information associated with the plurality of pixels. The system may generate a second latent representation by processing the first latent representation using a first machine-learning model trained to denoise latent light representations. The system may then generate color values for the plurality of pixels by processing at least the second latent representation using a second machine-learning model.
