📁 Data Preparation

AMASS

1. Please download the datasets from AMASS.
2. Download the required body models and placed them in ./support_data/body_models directory of this repository. For the SMPL+H body model, download it from http://mano.is.tue.mpg.de/. Please download the AMASS version of the model with DMPL blendshapes. You can obtain dynamic shape blendshapes, e.g. DMPLs, from http://smpl.is.tue.mpg.de.
3. Run ./data/prepare_data.py to preprocess the input data for faster training. The data split for training and testing data under Protocol 1 in our paper is stored under the folder ./data/data_split (from AvatarPoser).

python ./data/prepare_data.py --protocol [1, 2, 3] --root [path to AMASS]

Real-Captured Data

1. Please download our real-captured testing data from Google Drive. The data is preprocessed to the same format as our preprocessed AMASS data.
2. Unzip the data and place it in ./data directory of this repository.

🖥️ Requirements

• Python >= 3.9
• PyTorch >= 1.11.0
• pyrender
• trimesh
• human_body_prior
