[Day 2] NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis
Key Idea
NeRF presents a method to represent 3D scenes using a fully connected neural network. Given a set of 2D images of a scene, it learns to output the color and volume density of any 3D point, enabling high-quality view synthesis.
Why It Matters
3D scene representation and rendering have traditionally required complex data structures and models. NeRF's neural network-based approach provides a compact, continuous, and differentiable representation, pushing the boundaries of view synthesis.
Technical Bite
NeRF uses a neural network to model the volumetric scene function, and ray marching to render novel views. It leverages spatial coordinates as input and outputs RGB color and volume density.
Impact
Sparked interest in using deep learning for 3D scene representation and has influenced various subsequent works in the field of computer graphics and vision.
