摘　　要：虚拟现实技术发展迅速,但传统的虚拟现实系统大多存在着沉浸感不强、交互性差,不能让体验者沉浸在虚拟系统中等缺陷。综合这些因素,研究基于Unity3D平台,采用3Dmax场景建模工具,采用Java Script和C#语言实现交互功能,结合Occlus dk2完成交互式虚拟系统的开发并研究系统中所涉及的多项关键技术,包括碰撞体检测技术、三维建模技术、粒子特效技术、虚拟交互技术等等。实验结果表明,该虚拟交互系统能克服以往虚拟漫游的沉浸感不足、交互性差等缺点,用户在虚拟交互系统中可以体验到与真实场景相近的虚拟环境,并且可以与虚拟环境进行交互;将交互行为应用到虚拟漫游中对虚拟现实技术发展具有重要意义,具有简单和易实现等特点,拥有广阔的应用前景。Virtual reality technology has developed rapidly, but the traditional virtual reality system is lack of scene immersion, with poor interaction,which cannot let the users immersed in the virtual system. In synthesis of these factors,based on the Unity3D platform,using 3 Dmax as the scene modeling tool, the interaction is realized by JavaScript and C#. Combined with Ocuins dk2, the virtual interactive sys- tem is developed and its corresponding technologies are researched including collision detection,3D modeling,particle effects, virtual in- teraction and so on. Experimental results show that the system can overcome the shortcomings of poor immersion of virtual roaming and bad interaction. The users can experience the virtual environment close to the real scene and interact with it. It is significant for virtual re- ality technology to apply interaction into virtual roaming, simple and easy to implement, with broad application prospects.
