How to get the contact and stationary data?

[catherineytw]

Hi, thanks for sharing the code, really nice work!
In the past few days, I was trying to run the program on my data and was confused by several parameters.

1. What are the 'contact' and 'stationary' data in the command " python pipeline.py --contact_estimation 1 --vnect_2d_path ./data/VNect_data/vnect_2ds.npy --save_path './results/' --floor_known 0 --humanoid_path asset/physcap.urdf --skeleton_filename asset/physcap.skeleton --motion_filename ./data/VNect_data/motion.motion --contact_path results/contacts.npy --stationary_path results/stationary.npy " and how to get them?
2. What are the 'motion.motion' and 'ddd.mdd'? Since the VNect is not available to me (I applied for the access but was not approved yet), is it possible to generate these files using other methods?

Any answers will be highly appreciated.
