Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for neural shading. A processor may obtain a set of values that is indicative of surface properties of a set of materials associated with graphical content. The processor may provide, as an input to a machine learning model, the set of values, where the machine learning model includes learned parameters that are based on a plurality of values that are indicative of a plurality of surface properties of a plurality of materials. The processor may obtain, as an output of the machine learning model and based on the input and the learned parameters, a value associated with lighting corresponding to the surface properties of the set of materials associated with the graphical content. The processor may output an indication of the value.
