This repository is a PyTorch collection of Neural Radiance Field (NeRF) model implementations. It provides reimplementations of seven popular NeRF variants including the original NeRF, NeRF++, DVGO, Plenoxels, Mip-NeRF, and Mip-NeRF360. The library is designed for research use, offering easy extensibility for novel view synthesis tasks in 3D computer vision.
