Radiance Field Rendering

Radiance fields are volumetric representations of a scene using neural networks. Gaussian splatting is a technique to render these scenes efficiently by rasterizing a stretched oval of color.

[Edward Ahn] has a nice, high-level overview of how neural radiance fields differ from 3D gaussian splatting. In short: splatting is more akin to rasterization, while NeRFs are more similar to ray tracing. It’s a speed optimization that requires additional preprocessing.
