Code for Neural-GIF: Neural Generalized Implicit Functions for Animating People in Clothing(ICCV21)

https://nextcloud.mpi-klsb.mpg.de/index.php/s/FweAP5Js58Q9tsq

1. Install kaolin: https://github.com/NVIDIAGameWorks/kaolin

2. conda env create -f neuralgif.yml

3. conda activate neuralgif

 1. Edit configs/*yaml with correct path
        a. data/data_dir:
        b. data/split_file: <path to train/test split file> (see example in dataset folder)
        c. experiment/root_dir: training dir
        d. experiment/exp_name: <exp_name>
 2 . python trainer_shape.py --config=<path to config file>

1. python generator.py --config=<path to config file>

1. SMPL pose and shape parameters:  https://github.com/bharat-b7/IPNet

2. Save the registartion data and original scan data as: 
    
    a. data_dir/scan_dir: contain original scans
    b. data_dir/beta.npy: SMPL beta parameter of subject
    c. data_dir/pose.npz: SMPL pose parameters for all frames of scan

3. Prepare training data:
    python prepare_data/scan_data.py -data_dir=<path to data directory>

python visualisation/render_meshes.py -mesh_path=<folder containing meshes> -out_dir=<output dir>
