What is Neural Radiance Fields?

Neural Radiance Fields (NeRFs) are a technique in computer graphics and computer vision for representing 3D scenes using neural networks. A NeRF uses a neural network to learn a function that maps 3D coordinates and viewing directions to color and density. This allows for rendering novel views of complex scenes from a set of input images. They are commonly used for view synthesis, 3D reconstruction, and scene editing.
