Overview

NeRF implicitly represents a 3D scene with a multi-layer perceptron (MLP) $F: (\boldsymbol{x}, \boldsymbol{d}) \rightarrow (\boldsymbol{c}, \sigma)$ for some position $\boldsymbol{x} \in \mathbb{R}^3$ , view direction $\boldsymbol{d} \in [0, \pi) \times [0, 2\pi)$ , color $\boldsymbol{c}$ , and "opacity" $\sigma$ . Rendered results are spectacular.
