基于JACK的虚拟人行走建模与实现

针对目前Jack软件中人体直立行走仿真过程存在的缺陷(动作不自然问题、姿态转变存在突变现象),分析了Jack软件中人体运动模型及直立行走的控制方法,提出利用参数化关键帧技术对人体运动控制过程进行改进,通过改进,使得人体的行走仿真更加逼真、自然,有效地提高了人体运动仿真的真实感。结果将改进的运动控制流程应用到虚拟人体的弯腰走、携物走、跑、爬行、攀登、匍匐等广义行走仿真中,实现了人体各种姿态的行走动作,有效提高了jack软件在工程中的实际应用能力。

Design and Implementation of Virtual Human Walking in Jack

In light of the defects of virtual human walking in Jack,including low reliability of motion and break of pose-transformation,by analysing the human model and walking control technique in Jack,a parameter key framing technology was proposed to improve the process of walking control in this paper,and through the improvement,the human walking becomes more natural and more realistic. The advanced process of walking control was applied to general walking control of virtual human,for instance stoop down walking,...
