This tool is used to convert 17-point 3D skeleton into MMD motion (VMD) file. The code is naive and ugly but it works.
1. Copy a reference vmd file for retrieving version and model information.
2. Place your 3D predictions in './pred3d/' folder, and save the file names as '%08d.mat'. Several samples are provided in the folder.
3. Edit your frame range in line 53, in convert_pose.py.
4. Edit your output filename in convert_pose.py, last line.
5. You can now import this into your MMD. Remember to 'OFF' the IK points.
This work is under WTFPL.
You can do WHAT THE FUCK YOU WANT TO.
