AI-Driven Bio-Inspired Procedural Animation Framework for Dynamic Game Character Locomotion and Facial Expression Generation

Abstract

This research article introduces an AI-driven bio-inspired procedural animation framework designed for generating dynamic and realistic game character locomotion and facial expressions. The framework integrates artificial intelligence techniques, specifically deep learning and reinforcement learning, with principles of biological motion to create a system capable of producing complex and nuanced animations in real-time. The locomotion component employs a hierarchical control structure inspired by spinal cord organization, enabling adaptive gait patterns across varying terrains and speeds. The facial expression generator utilizes a blendshape model driven by a neural network trained on extensive motion capture data of human facial performances. Furthermore, we introduce a novel reward function that incorporates principles of both realism and expressiveness to optimize animation quality. Rigorous experiments demonstrate the framework's ability to generate compelling character movements and emotional expressions, surpassing traditional methods in terms of realism, adaptability, and computational efficiency. The results highlight the potential of AI-driven bio-inspired animation for enhancing the immersive quality of interactive entertainment experiences whilst reducing dependence on computationally expensive manual animation processes. The proposed system advances the state-of-the-art in procedural animation and provides a valuable tool for game developers and animators seeking to create engaging and lifelike characters.
