【摘要】 对人工智能（AI）驱动的虚拟角色动画从预设式制作向实时生成与交互的范式转型进行探讨。系统分析基于深度学习、强化学习及多模态条件生成的核心技术原理，剖析其如何构建“感知—决策—生成”的实时交互闭环。进一步指出，技术变革正推动动画设计范式从创作单一表演转向设计行为系统。尽管在情感表现的艺术细腻度等方面仍面临挑战，但AI无疑正重塑着虚拟角色的内涵，为构建高沉浸感、强交互性的数字世界提供核心动力。更多还原

【Abstract】 This paper explores the paradigm transformation of virtual character animation driven by Artificial Intelligence(AI) from preset production to real-time generation and interaction.It systematically analyzes core technical principles based on deep learning,reinforcement learning and multimodal conditional generation,and analyzes how to construct a "perception-decision-generation" real-time interactive closed-loop.It is further pointed out that technological innovation is driving the animation design paradigm from creating isolated performance to designing behavioral systems.Although there are still challenges in the artistic fineness of emotional expression,AI is undoubtedly reshaping the connotation of virtual characters and providing the core momentum for building a digital world with high immersion and strong interactivity.更多还原
