This is still a research project in progress.
This project aims for benchmarking several state-of-the-art large-scale radiance fields algorithms. We exchangely use terms "unbounded NeRF" and "large-scale NeRF" because we find the techniques behind them are closely related.
Instead of pursuing a big and complicated code system, we pursue a simple code repo with SOTA performance for unbounded NeRFs.
You are expected to get the following results in this repository:
| Benchmark | Methods | PSNR |
|---|---|---|
| Unbounded Tanks & Temples | NeRF++ | 20.49 |
| Unbounded Tanks & Temples | Plenoxels | 20.40 |
| Unbounded Tanks & Temples | DVGO | 20.10 |
| Unbounded Tanks & Temples | Ours | 20.85 |
| Mip-NeRF-360 Benchmark | NeRF | 24.85 |
| Mip-NeRF-360 Benchmark | NeRF++ | 26.21 |
| Mip-NeRF-360 Benchmark | Mip-NeRF-360 | 28.94 |
| Mip-NeRF-360 Benchmark | DVGO | 25.42 |
| Mip-NeRF-360 Benchmark | Ours | 28.98 |

Expand / collapse installation steps.
-
Clone this repository. Use depth == 1 to avoid download a large history.
git clone --depth=1 [email protected]:sjtuytc/LargeScaleNeRFPytorch.git mkdir data mkdir logs
-
Create conda environment.
conda create -n large-scale-nerf python=3.9 conda activate large-scale-nerf
-
Install pytorch and other libs. Make sure your Pytorch version is compatible with your CUDA.
pip install --upgrade pip conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.6 -c pytorch -c nvidia pip install -r requirements.txt
-
Install grid-based operators to avoid running them every time, cuda lib required. (Check via "nvcc -V" to ensure that you have a latest cuda.)
apt-get install g++ build-essential # ensure you have g++ and other build essentials, sudo access required. cd FourierGrid/cuda python setup.py install cd ../../
-
Install other libs used for reconstructing custom scenes. This is only needed when you need to build your scenes.
sudo apt-get install colmap sudo apt-get install imagemagick # required sudo accesss conda install pytorch-scatter -c pyg # or install via https://github.com/rusty1s/pytorch_scatter
You can use laptop version of COLMAP as well if you do not have access to sudo access on your server. However, we found if you do not set up COLMAP parameters properly, you would not get the SOTA performance.

4.1 Download processed data.
- Disclaimer: users are required to get permission from the original dataset provider. Any usage of the data must obey the license of the dataset owner.
(1) Unbounded Tanks & Temples. Download data from here. Then unzip the data.
cd data
gdown --id 11KRfN91W1AxAW6lOFs4EeYDbeoQZCi87
unzip tanks_and_temples.zip
cd ../(2) The Mip-NeRF-360 dataset.
cd data
wget http://storage.googleapis.com/gresearch/refraw360/360_v2.zip
mkdir 360_v2
unzip 360_v2.zip -d 360_v2
cd ../(3) San Fran Cisco Mission Bay. What you should know before downloading the data:
- Our processed waymo data is significantly smaller than the original version (19.1GB vs. 191GB) because we store the camera poses instead of raw ray directions. Besides, our processed data is more friendly for Pytorch dataloaders. Download the data in the Google Drive. You may use gdown to download the files via command lines. If you are interested in processing the raw waymo data on your own, please refer to this doc.
The downloaded data would look like this:

4.2 Train models and see the results!
You only need to run "python run_FourierGrid.py" to finish the train-test-render cycle. Explanations of some arguments:
--program: the program to run, normally --program train will be all you need.
--config: the config pointing to the scene file, e.g., --config FourierGrid/configs/tankstemple_unbounded/truck_single.py.
--num_per_block: number of blocks used in large-scale NeRFs, normally this is set to -1, unless specially needed.
--render_train: render the trained model on the train split.
--render_train: render the trained model on the test split.
--render_train: render the trained model on the render split.
--exp_id: add some experimental ids to identify different experiments. E.g., --exp_id 5.
--eval_ssim / eval_lpips_vgg: report SSIM / LPIPS(VGG) scores.While we list major of the commands in scripts/train_FourierGrid.sh, we list some of commands below for better reproducibility.

We will mainly work on grid-based models later because they are simple and fast. Run the following command to reproduce the old Block-NeRF experiments:
bash scripts/block_nerf_train.sh
bash scripts/block_nerf_eval.shExpand / collapse steps for building custom NeRF world.
-
Put your images under data folder. The structure should be like:
data |——————Madoka // Your folder name here. | └——————source // Source images should be put here. | └——————---|1.png | └——————---|2.png | └——————---|...
The sample data is provided in our Google drive folder. The Madoka and Otobai can be found at this link.
-
Run COLMAP to reconstruct scenes. This would probably cost a long time.
python FourierGrid/tools/imgs2poses.py data/Madoka
You can replace data/Madoka by your data folder. If your COLMAP version is larger than 3.6 (which should not happen if you use apt-get), you need to change export_path to output_path in the colmap_wrapper.py.
-
Training NeRF scenes.
python FourierGrid/run_FourierGrid.py --config configs/custom/Madoka.py
You can replace configs/custom/Madoka.py by other configs.
-
Validating the training results to generate a fly-through video.
python FourierGrid/run_FourierGrid.py --config configs/custom/Madoka.py --render_only --render_video --render_video_factor 8

We refer to the code and data from DVGO, nerf-pl and SVOX2, thanks for their great work!
We track weekly NeRF papers and classify them. All previous published NeRF papers have been added to the list. We provide an English version and a Chinese version. We welcome contributions and corrections via PR.
We also provide an excel version (the meta data) of all NeRF papers, you can add your own comments or make your own paper analysis tools based on the structured meta data.
Thanks goes to these wonderful people (emoji key):
