Electronic device and method of scene rendering

Abstract

An electronic device, including: at least one processor; and a memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the electronic device to: select a three-dimensional (3D) point included in a scene corresponding to a viewpoint, using a first machine learning-based model, obtain a first partial bidirectional scattering distribution function (BSDF) value based on a view direction toward the 3D point from the viewpoint, a ray direction sampled at the 3D point, and material information, obtain a second partial BSDF value using a second machine learning-based model, wherein the second machine learning-based model is connected to the first machine learning-based model, determine a full BSDF value for the ray direction at the 3D point based on the first partial BSDF value and the second partial BSDF value, and generate an image corresponding to the scene by determining a value of a pixel corresponding to the view direction based on the sampled ray direction, the full BSDF value, and a probability density function (PDF) value.
