一个情感驱动的3D虚拟角色行为动画创作工具

A Behavior Animation Developing Tool for Emotion Driven 3D Virtual Character

情感作为人类具有智能的一个重要体现,是创建丰富细腻的虚拟智能体的不可或缺的环节。本文结合认知对情感的影响,提出一个改进的情感建模方法和一种新的行为建模方法,设计具体的情感情境,并通过行为树的行为组织形式对虚拟环境中的行为进行管理,以产生具体、真实的虚拟角色情感行为。提出"个性-情感-情绪"的三层情感层次结构,并最后完成了一个实验系统。实验结果证明,该情感模型和行为组织模型能有效地反映虚拟角色在虚拟环境中的智能情感行为。

Emotion is an important aspect of human intelligence and has been playing a significant role in creating virtual agent.Taken into account the influence of cognition to the emotion,an improved computing emotional model and a new form of behavior model are proposed.The paper designs the idiographic environment of emotion,and manages the behaviors through the form of behavior-tree to create the material and realistic virtual character emotion behavior,and brings forward the three-level structure of emotion formed as ＂personality-emotion-mood＂,then at last achieves an experimental system which proves the emotion model and behavior organizing model to be effective in creating intelligent emotion behavior in the virtual environment.
