| 摘 要： | 虚拟人是虚拟场景中最为活跃的因素,但是虚拟人的动作却不能由用户灵活的个性化的设计,为此设计了一个基于VRML的虚拟人动作描述语言(VHADL),采用H-Anim标准构建了虚拟人的模型,定义3个参照系使得用户更准确的描述动作、指定参数,使用反向动力学来确定肢体位置,并定义元动作和一些复合算子来合成复杂动作,最后给出了一个送咖啡的例子.

| Abstract: | Virtual human is the most active element of the virtual reality,whereas the actions of virtual human cannot be designed indi-vidually by user-selves.A VRML-based action description language of virtual human(VHADL) is proposed.The model of virtual human is constructed by the H-Anim standard,and three reference systems are defined for users to describe actions or assign parameters accurately,and the positions of some parts of body are assigned by Inverse Kinetics,what is more,complex actions are composed of some mate actions defined previously and some operators for combining.At last,an example of delivering coffee is shown. |
