What is a Neural Radiance Fields (NeRF)?
Definition
Neural Radiance Fields (NeRF) are a novel approach in 3D computer graphics and photography. NeRFs use deep learning to render 3D scenes by representing them as volumetric radiance fields. This involves inferring the color and density of a scene at any given point and viewpoint by processing a collection of 2D images instead of traditional geometric models. This technique fundamentally transforms how we understand and generate 3D spaces, offering high-fidelity, photo-realistic visuals with intricate details and lighting effects. NeRFs are particularly effective for applications involving reconstruction of real-world environments and synthetic image generation.
