PIMT: Physics-Based Interactive Motion Transition for Hybrid Character Animation
MM '24: Proceedings of the 32nd ACM International Conference on MultimediaPages 10497–10505https://doi.org/10.1145/3664647.3681582Motion transitions, which serve as bridges between two sequences of character animation, play a crucial role in creating long variable animation for real-time 3D interactive applications. In this paper, we present a framework to produce hybrid character ...

Automatic Curriculum for Unsupervised Reinforcement Learning
AAMAS '24: Proceedings of the 23rd International Conference on Autonomous Agents and Multiagent SystemsPages 2002–2010Unsupervised reinforcement learning (URL) relies on carefully designed training objectives rather than task rewards to learn general skills. However, we lack quantitative evaluation metrics for URL but mainly rely on visualizations of trajectories for ...

Synthesizing Physical Character-Scene Interactions
SIGGRAPH '23: ACM SIGGRAPH 2023 Conference ProceedingsArticle No.: 63, Pages 1–9https://doi.org/10.1145/3588432.3591525Movement is how people interact with and affect their environment. For realistic character animation, it is necessary to synthesize such interactions between virtual characters and their surroundings. Despite recent progress in character animation using ...

Offline Imitation Learning Using Reward-free Exploratory Data
ACAI '22: Proceedings of the 2022 5th International Conference on Algorithms, Computing and Artificial IntelligenceArticle No.: 94, Pages 1–9https://doi.org/10.1145/3579654.3579753Offline imitative learning(OIL) is often used to solve complex continuous decision-making tasks. For these tasks such as robot control, automatic driving and etc., it is either difficult to design an effective reward for learning or very expensive and ...

ASE: large-scale reusable adversarial skill embeddings for physically simulated characters
ACM Transactions on Graphics (TOG), Volume 41, Issue 4Article No.: 94, Pages 1–17https://doi.org/10.1145/3528223.3530110The incredible feats of athleticism demonstrated by humans are made possible in part by a vast repertoire of general-purpose motor skills, acquired through years of practice and experience. These skills not only enable humans to perform complex tasks, ...
