Two2Four: Generative Quadruped Puppeteering from Human Motion

Two2Four is a new human-to-quadruped puppeteering system that turns ordinary human motion into plausible animal animation. Built on a two-stage diffusion model trained only on quadruped motion, it aims to replace brittle retargeting rigs with something more automatic and controllable. The system also supports head and limb-level puppeteering for finer direction.
