Motion Avatar: Generate Human and Animal Avatars with Arbitrary Motion
This addresses a persistent problem in film-making, gaming, AR/VR, and human-robot interaction by enabling dynamic 3D character generation, though it is incremental in extending existing techniques to animals.
The paper tackles the challenge of integrating 3D avatar mesh generation with motion sequences for both humans and animals, proposing Motion Avatar to automatically generate high-quality customizable avatars with motions from text queries, and introduces a dataset of 300,000 text-motion pairs for animals.
In recent years, there has been significant interest in creating 3D avatars and motions, driven by their diverse applications in areas like film-making, video games, AR/VR, and human-robot interaction. However, current efforts primarily concentrate on either generating the 3D avatar mesh alone or producing motion sequences, with integrating these two aspects proving to be a persistent challenge. Additionally, while avatar and motion generation predominantly target humans, extending these techniques to animals remains a significant challenge due to inadequate training data and methods. To bridge these gaps, our paper presents three key contributions. Firstly, we proposed a novel agent-based approach named Motion Avatar, which allows for the automatic generation of high-quality customizable human and animal avatars with motions through text queries. The method significantly advanced the progress in dynamic 3D character generation. Secondly, we introduced a LLM planner that coordinates both motion and avatar generation, which transforms a discriminative planning into a customizable Q&A fashion. Lastly, we presented an animal motion dataset named Zoo-300K, comprising approximately 300,000 text-motion pairs across 65 animal categories and its building pipeline ZooGen, which serves as a valuable resource for the community.
