【摘要】 现实世界中,语义在人与环境的交互过程中起到了重要的作用,它是实现和谐交互的基础。然而,目前在虚拟场景编辑系统中,往往只关注于交互对象的几何信息,而没有考虑到对象的语义特征,用户的交互也只是仅限于在几何层面上进行。本文描述了语义的概念和应用,提出基于语义的虚拟场景编辑系统的原型结构,探讨了虚拟场景编辑系统中语义模型的设计,语义交互的过程以及对于虚拟场景的编辑技术。实验证明,基于语义的虚拟场景编辑技术能够丰富不仅能提高交互的效率,实现和谐的人机交互,还能从语义层次上对交互进行响应,实现复杂的交互任务。更多还原

【Abstract】 In the reality world,Semantics plays an important role in the interaction between human and environments,and lays the groundwork for the harmonious interaction.However,the present virtual scene editing system concerns geometric features of scene objects but not semantic information.This article describes the concept and the application of semantics,designs the semantics-based three-dimensional scene edit system,focuses on the design of semantic model,the process of semantics interaction and the method of terrain edit.It’s proved that semantics-based virtual scene editing can rich interactive editing style,improve editing efficiency,and respond to complex interactive tasks.更多还原
