3D Avatar Pipeline
Neural avatar pipeline: PIFuHD implicit mesh → RigNet automatic rigging → lightweight pose estimation → Mixamo animation. 16 GitHub stars.

Earlier exploration of a realistic 3D avatar pipeline — a sibling to IMAGEimate. Combines two state-of-the-art networks (PIFu and RigNet) with off-the-shelf pose estimation and Mixamo's animation library to produce rigged, animatable duplicates from a single image.
techniques
- PIFuHD — single photo → predicted 3D mesh
- RigNet — neural rigging that predicts skeleton joints, bones, and skinning weights
- OpenPose (lightweight PyTorch) — single-shot pose estimation
- Mixamo — Adobe's character animation library for re-targeting
