If you want a platform with a modular implementation of Neural Radiance Fields (NeRF) that you can customize, Nerfstudio is a good option. It's an open-source, modular API that lets you create, train and test NeRFs. The platform supports several built-in NeRF methods, including Nerfacto, Instant-NGP and Mip-NeRF, but you can also add third-party methods. With its modular design, abundant learning materials and a config system, Nerfstudio is good for people with all levels of expertise, so it's good for casual exploration and serious research and development.
