## Hardware
* OS: Ubuntu 18.04
* NVIDIA GPU with **CUDA>=11.1** (tested with 1 RTX3090)
## Installation
We have tested the code on Python 3.8.0 and PyTorch 1.8.1, while a newer version of pytorch should also work.
The steps of installation are as follows:
* Clone this repo by `git clone --recursive https://github.com/zju3dv/Mirror-NeRF`
* Python>=3.8 (installation via [Anaconda](https://www.anaconda.com/) is recommended, use `conda create -n mirror_nerf python=3.8` to create a conda environment and activate it by `conda activate mirror_nerf`)
* Python libraries
* Install requirements by `pip install -r requirements.txt`
* Install PyTorch 1.8.1 by `pip install torch==1.8.1+cu111 torchvision==0.9.1+cu111 -f https://download.pytorch.org/whl/torch_stable.html`
* [Optional] If you want to use [tiny-cuda-nn](https://github.com/NVlabs/tiny-cuda-nn) for acceleration, install [tiny-cuda-nn PyTorch extension](https://github.com/NVlabs/tiny-cuda-nn#pytorch-extension) by `pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch`
## Data
We support synthetic datasets (`datasets/blender.py`) and real datasets (`datasets/real_arkit.py`).
For customized datasets with camera poses reconstructed by [COLMAP](https://colmap.github.io/), you can refer to `datasets/real_colmap.py`.
### Data download
Download our captured synthetic and real **datasets** from [here](https://drive.google.com/drive/folders/1fBeIAI64v5GRoIo7eceGnbqS0sF07YN_?usp=sharing).
Download our **pretrained models** on the synthetic and real datasets from [here](https://drive.google.com/drive/folders/1BFAMPw1T64es-o-2rMzBNbj01VxJFF4b?usp=sharing).
> Notes: For pretrained models with "tcnn" in the filename, select `MODEL_TYPE="nerf_tcnn"` in `run.sh`.
For pretrained models of D-NeRF, please refer to [D-NeRF](https://github.com/albertpumarola/D-NeRF#download-pre-trained-weights) repository.
## Running
We integrate training, testing and applications in one script `run.sh`,
```
bash run.sh {MODE} {GPU_ID}
```
`MODE`:
> `1` for evaluation (Novel View Synthesis),
>
> `2` for extracting mesh,
>
> `3` for placing new mirrors (application),
>
> `4` for reflecting newly placed objects (application),
>
> `5` or `52` for controlling mirror roughness (application),
>
> `6` for reflection substitution (application),
>
> other numbers like `0` for training.
**Please configure the settings in `run.sh` before running.**
For example, choose the `DATASET` and `MODEL_TYPE`.
> Notes: For acceleration, use `MODEL_TYPE="nerf_tcnn"`.
>
> For scenes with accurate camera poses (like synthetic scenes), `MODEL_TYPE="nerf"` is recommended.
>
> For some real captures with inaccurate camera poses, `MODEL_TYPE="nerf_tcnn"` is recommended.
For evaluation and applications, specify the `LOG` (necessary), `SUBSTITUTION_LOG` (for reflection substitution) and `OBJ_CKPT_PATH` (for reflecting newly placed objects).
**For more configurations, see `opt.py`.**
The results of training will be automatically stored in the `log/` directory.
The results of evaluation and application will be automatically stored in the `results/` directory.

## Acknowledgement
This repository is developed upon [nerf_pl](https://github.com/kwea123/nerf_pl).
And we use parts of the code of [D-NeRF](https://github.com/albertpumarola/D-NeRF) for object models used in the application of reflecting newly placed objects, and parts of the code of [torch-ngp](https://github.com/ashawkey/torch-ngp) for using tiny-cuda-nn if acceleration is needed.
Thanks for these great projects!
