The following was a research project initially inspired by CLIPMatrix. However, after the release of CLIP-Actor and AvatarCLIP I've decided to just release my code since those works have extensively documented this domain.
The main difference is that this uses meshes which are much faster and less memory-intensive, additionally I explore multiple independent optimizable parameters
IMO there is still huge for improvement on this topic and hopefully this repo allows everyone to perform quick experimentation without needing large compute - Enjoy! 🎉
This project is for research purposes only
This codebase uses SMPL-X Models and the smplx pip library. By using this code you agree to the SMPL-X Model License and smplx License
This code base relies on nvdiffmodeling and in turn nvdiffrast.
Get started by testing out the features through the collabs
