Philosophy

All-in-one repository for state-of-the-art NeRFs.

nerfstudio provides a simple API that allows for a seamless and simplified end-to-end process of creating, training, and visualizing NeRFs. The library supports a more interpretable implementation of NeRFs by modularizing each component. With more modular NeRFs, not only does your code become far more user-friendly, but using this framework also makes it easier for the community to build upon your implementation.

It’s as simple as plug and play with nerfstudio!

Ontop of our API, we are commited to providing learning resources to help you understand the basics of (if you're just getting start), and keep up-to-date with (if you're a seasoned veteran) all things NeRF. As researchers, we know just how hard it is to get onboarded with this next-gen technology. So we're here to help with tutorials, documentation, and more!

Finally, have feature requests? Want to add your brand-spankin'-new NeRF model? Have a new dataset? We welcome any and all contributions!

We hope nerfstudio enables you to build faster :hammer: learn together :books: and contribute to our NeRF community :sparkling_heart:.

Quickstart

The quickstart will help you get started with the default vanilla nerf trained on the classic blender lego scene. For more complex changes (e.g. running with your own data/ setting up a new NeRF graph, please refer to our references.

1. Installation: Setup the environment

This repository is tested with CUDA 11.3. Make sure to install Conda before preceding.

Create the python environment

conda create --name nerfstudio python=3.8.13
conda activate nerfstudio
python -m pip install --upgrade pip

Clone the repo

git clone git@github.com:plenoptix/nerfstudio.git

Install dependencies and nerfstudio as a library

cd nerfstudio
pip install -e .

Install tiny-cuda-nn (tcnn) to run instant_ngp

pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 -f https://download.pytorch.org/whl/torch_stable.html
pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch

Install tab completion for nerfstudio (bash & zsh)

nf-install-cli

Run the test cases

pytest tests

2. Getting the data

Download the original NeRF Blender dataset. We support the major datasets and allow users to create their own dataset, described in detail here.

python scripts/downloads/download_data.py --dataset=blender

Use --help to view all currently available datasets. The resulting script should download and unpack the dataset as follows:

|─ nerfstudio/
   ├─ data/
   |  ├─ blender/
   |     ├─ fern/
   |     ├─ lego/
         ...
      |- <dataset_format>/
         |- <scene>
         ...

3. Training a model

To run with all the defaults, e.g. vanilla nerf method with the blender lego image

# To see what models are available.
python scripts/train.py --help

# Run a vanilla nerf model.
python scripts/train.py vanilla_nerf

# Run a faster version with instant ngp using tcnn (without the viewer).
python scripts/train.py instant_ngp

3.x Training a model with the viewer

Make sure to forward a port for the websocket to localhost. The default port is 7007, which you should be expose to localhost:7007.

# with the default port
python scripts/train.py instant_ngp --viewer.enable

# with a specified websocket port
python scripts/train.py instant_ngp --viewer.enable --viewer.websocket-port=7008

# with the viewer bridge server as a separate process
# in one terminal, start the bridge server:
viewer-bridge-server # or equivalently, python scripts/run_viewer_bridge_server.py
# in another terminal, start training:
python scripts/train.py instant_ngp --viewer.enable --viewer.no-launch-bridge-server

4. Visualizing training runs

We support multiple methods to visualize training, the default configuration uses Tensorboard. More information on logging can be found here.

tensorboard --logdir outputs/

5. Rendering a trajectories during inference

python scripts/eval.py render-trajectory --load-config=outputs/blender_lego/instant_ngp/2022-07-07_230905/config.yml--traj=spiral --output-path=output.mp4

6. In-depth guide

For a more in-depth tutorial on how to modify/implement your own NeRF Graph, please see our walk-through.

Supported Features

We provide the following support strucutures to make life easier for getting started with NeRFs. For a full description, please refer to our features page.

If you are looking for a feature that is not currently supported, please do not hesitate to contact the Plenoptix team!

• :mag_right: Web-based visualizer that allows you to:
  • Visualize training in real-time + interact with the scene
  • Create and render out scenes with custom camera trajectories
  • View different output types
  • And more!
• :pencil2: Support for multiple logging interfaces (Tensorboard, Wandb), code profiling, and other built-in debugging tools
• :chart_with_upwards_trend: Easy-to-use benchmarking scripts on the Blender dataset
• :iphone: Full pipeline support (w/ Colmap or Record3D) for going from a video on your phone to a full 3D render. Follow our step-by-step tutorial. (TODO: walk-through page on end-to-end pipeline from capture -> render)
