Dual-Space NeRF

[3DV-2022] The official repo for the paper "Dual-Space NeRF: Learning Animatable Avatars and Scene Lighting in Separate Spaces".

[paper / video]

Model

We provide all checkpoints and X_smpl_vertices at here.

Installation

  1. Clone this repository:

    git clone https://github.com/zyhbili/Dual-Space-NeRF.git
    
  2. Install required python packages:

    pip install -r requirements.txt
    
  3. Download the SMPL model (neutral) from:

    https://smpl.is.tue.mpg.de/
    

    and modify the _C.DATASETS.SMPL_PATH in configs/defaults.py.

Dataset

Download and unzip ZJU_Mocap, then modify the _C.DATASETS.ZJU_MOCAP_PATH in configs/defaults.py.

Prepare Human3.6M following Animatable_NeRF and modify the _C.DATASETS.H36M_PATH in configs/defaults.py.

Run the code

Take ZJU-Mocap 313 as an example, other configs files are provided in configs/{h36m,zju_mocap}.

Command Lines

Train Dual Space NeRF

python3 main.py -c configs/zju_mocap/313.yml --exp 313

Test Dual Space NeRF

python3 test.py -c configs/zju_mocap/313.yml --ckpt [ckpt_path.pth] --exp 313

Novel pose synthesis

Download CoreView_313_op3.zip, and unzip it into novelpose_examples\

python3 novel_pose_vis.py -c configs/zju_mocap/313.yml --ckpt ckpt/313/model_epoch_0000200.pth --exp 313_op3

The results are saved into motion_transfer/313_op3/

For customed pose seq, you need to prepare the SMPL vertices as provided in the ZIP file and then modify the novel_pose_dataset.vertices_dir in novel_pose_vis.py

Lighting MLP visualization

python3 vis_lighting.py -c configs/zju_mocap/313.yml --ckpt ckpt/313/model_epoch_0000200.pth --exp 313_lighting

The results are saved into lighting_vis/313_lighting/
