A collaboration friendly studio for NeRFs
It’s as simple as plug and play with nerfstudio!
Nerfstudio provides a simple API that allows for a simplified end-to-end process of creating, training, and testing NeRFs. The library supports a more interpretable implementation of NeRFs by modularizing each component. With more modular NeRFs, we hope to create a more user-friendly experience in exploring the technology.
This is a contributor-friendly repo with the goal of building a community where users can more easily build upon each other's contributions. Nerfstudio initially launched as an opensource project by Berkeley students in KAIR lab at Berkeley AI Research (BAIR) in October 2022 as a part of a research project (paper). It is currently developed by Berkeley students and community contributors.
We are committed to providing learning resources to help you understand the basics of (if you're just getting started), 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!
Have feature requests? Want to add your brand-spankin'-new NeRF model? Have a new dataset? We welcome any and all contributions! Please do not hesitate to reach out to the nerfstudio team with any questions via Discord.
We hope nerfstudio enables you to build faster 🔨 learn together 📚 and contribute to our NeRF community 💖.
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.
You must have an NVIDIA video card with CUDA installed on the system. This library has been tested with version 11.3 of CUDA. You can find more information about installing CUDA here
Nerfstudio requires python >= 3.7. We recommend using conda to manage dependencies. Make sure to install Conda before proceeding.
conda create --name nerfstudio -y python=3.8
conda activate nerfstudio
python -m pip install --upgrade pipInstall pytorch with CUDA (this repo has been tested with CUDA 11.3 and CUDA 11.7) and tiny-cuda-nn
For CUDA 11.3:
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 -f https://download.pytorch.org/whl/torch_stable.html
pip install ninja git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torchFor CUDA 11.7:
pip install torch==1.13.1 torchvision functorch --extra-index-url https://download.pytorch.org/whl/cu117
pip install ninja git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torchSee Dependencies in the Installation documentation for more.
Easy option:
pip install nerfstudioOR if you want the latest and greatest:
git clone https://github.com/nerfstudio-project/nerfstudio.git
cd nerfstudio
pip install --upgrade pip setuptools
pip install -e .OR if you want to skip all installation steps and directly start using nerfstudio, use the docker image:
See Installation - Use docker image.
The following will train a nerfacto model, our recommended model for real world scenes.
# Download some test data:
ns-download-data nerfstudio --capture-name=poster
# Train model
ns-train nerfacto --data data/nerfstudio/posterIf everything works, you should see training progress like the following:
Navigating to the link at the end of the terminal will load the webviewer. If you are running on a remote machine, you will need to port forward the websocket port (defaults to 7007).
It is possible to load a pretrained model by running
ns-train nerfacto --data data/nerfstudio/poster --load-dir {outputs/.../nerfstudio_models}This will automatically start training. If you do not want it to train, add --viewer.start-train False to your training command.
Once you have a NeRF model you can either render out a video or export a point cloud.
First we must create a path for the camera to follow. This can be done in the viewer under the "RENDER" tab. Orient your 3D view to the location where you wish the video to start, then press "ADD CAMERA". This will set the first camera key frame. Continue to new viewpoints adding additional cameras to create the camera path. We provide other parameters to further refine your camera path. Once satisfied, press "RENDER" which will display a modal that contains the command needed to render the video. Kill the training job (or create a new terminal if you have lots of compute) and run the command to generate the video.
Other video export options are available, learn more by running
ns-render --helpWhile NeRF models are not designed to generate point clouds, it is still possible. Navigate to the "EXPORT" tab in the 3D viewer and select "POINT CLOUD". If the crop option is selected, everything in the yellow square will be exported into a point cloud. Modify the settings as desired then run the command at the bottom of the panel in your command line.
Alternatively you can use the CLI without the viewer. Learn about the export options by running
ns-export pointcloud --helpUsing an existing dataset is great, but likely you want to use your own data! We support various methods for using your own data. Before it can be used in nerfstudio, the camera location and orientations must be determined and then converted into our format using ns-process-data. We rely on external tools for this, instructions and information can be found in the documentation.

We provide other models than nerfacto, for example if you want to train the original nerf model, use the following command
ns-train vanilla-nerf --data DATA_PATHFor a full list of included models run ns-train --help.
Each model contains many parameters that can be changed, too many to list here. Use the --help command to see the full list of configuration options.
ns-train nerfacto --helpWe support three different methods to track training progress, using the viewer, tensorboard, and Weights and Biases. You can specify which visualizer to use by appending --vis {viewer, tensorboard, wandb, viewer+wandb, viewer+tensorboard} to the training command. Simultaneously utilizing the viewer alongside wandb or tensorboard may cause stuttering issues during evaluation steps. The viewer only works for methods that are fast (ie. nerfacto, instant-ngp), for slower methods like NeRF, use the other loggers.
And that's it for getting started with the basics of nerfstudio.
