What is Neural Radiance Fields (NeRF)?

How it works

NeRF (Neural Radiance Field) is a technique for reconstructing 3D scenes from a collection of 2D photographs. A neural network learns to represent the volumetric appearance of a scene, allowing you to render new views from any angle. While NeRF itself is primarily used for 3D reconstruction and virtual photography, the underlying concepts influence modern AI video generators. Some models use NeRF-inspired representations to maintain 3D consistency during video generation, producing more physically plausible camera movements. Understanding NeRF helps explain why some AI-generated camera movements look natural while others produce impossible geometry.
