You can get CHI3D dataset here

You can get SMPL-X here

You can get contact_regions.json here

Pretrained Model

The pretrained models can be downloaded here. After downloading, place checkpoint_diffusion_ci3d and checkpoint_guidenet_ci3d in the ContactGen/.

Training

Diffusion module should be trained first

python train_diffusion.py

Next you can train guidenet

python train_guidenet.py

Sampling

python sample.py

It will generate samples in the output_diffusion_epoch1000_ci3d

Visualizing

python visualize.py output_diffusion_epoch1000_ci3d/???_human_pred.pkl

You can visualize overall diffusion steps using visualize.py

contactgen's Issues

About evaluation

Thanks for your great work. I am curious about how to compute the evaluation metrics. Is it possible to provide the evelatuion scripts?

Pretrained weights

Hi,

Great paper! Will you provide the pretrained weights?
