【摘要】 虚拟环境的复杂交互特性体现之一就是操作者与虚拟造型的拖放动作。在基于虚拟现实建模语言的虚拟环境中,利用Drag传感器可有效实现拖放功能。归纳了VRML中Drag传感器节点的域、事件和语法结构,给出了在虚拟环境中对虚拟造型拖放动作的设计方法和步骤,为提升虚拟场景及造型的交互性提供了支撑,是复杂虚拟场景构建的重要基础工作。更多还原

【Abstract】 Drag motion between users and virtual models is the key for complex interactive characteristics in virtual environment(VE).In the VE based on Virtual Reality Modeling Language(VRML),the interaction functions are realized with Drag sensors(DSs).The fields,events and syntax of DSs are concluded,presented the method and process of DSs in VE.The research supports to promote the interactive characteristics of virtual sense and models as the fundamentals of complex virtual sense building.更多还原
