NVlabs/instant-ngp ? reverse-engineered prompt

Build me a desktop app that can train and view neural graphics models in real time from a folder or file I drop in. I want to be able to load a NeRF dataset, a 3D model for SDFs, a high resolution image, or a volume file, then watch it learn fast and render interactively in a simple GUI. Please include basic camera controls, training on and off, snapshot save and load, a way to make a camera path for recording videos, and options to switch render modes and adjust exposure. It should also support converting a trained NeRF or SDF into a mesh. If there are any current setup details or GPU requirements I should know about, look them up online and make the project work as smoothly as possible on modern NVIDIA hardware.
