Technical explanation of NeRF

Abstract

In 2020, a sensational new view synthesis technique called NeRF was announced. This method is based on volume rendering and represents the distribution of radiance in space (radiance field) using neural networks, demonstrating the new possibilities of deep learning. Since the announcement of NeRF, numerous derivative methods have been proposed in the field of computer vision, creating a buzz. This paper focuses on explaining the original paper by Mildenhall et al.
