基于Jack的虚拟环境中一种防止穿越的实现

A Penetration Avoidance Method in Jack-based VE

在虚拟环境下虚拟人手和虚拟物体的交互中,会发生穿越现象。为了解决穿越问题,在人体模型系统Jack的虚拟环境中,根据约束Constraint对象的特点,利用Constraint对象来模拟物体对人手阻挡作用,并利用约束队列实现了对场景中Constraint对象的管理,达到防穿越的效果。

In Virtual Environment(VE),the hand of virtual human will penetrate through the virtual object.In order to get a non-penetration VE,instance of Constraint is utilized to simulate the effect of interaction between the hand and the object,and Constraint queue is used to manipulate Constraints in VE.
