基于虚拟现实的室内仿真操作系统研究与应用

随着人们对于居住环境要求的提高、家居设计行业的需求加大,传统的设计图纸不能让用户直观地感受到装修效果,装修效果往往不能够让用户满意。基于虚拟现实技术对室内家居仿真操作系统进行研究,设计并制作了三维家居模型,研究并制作了虚拟角色骨骼动画。系统设计过程中充分集成网格建模、Biped骨骼关键帧技术、自动寻路检测算法、角色管理器调用、碰撞体检测技术、射线检测技术,并运用Oracle数据库和SQLite数据库对用户操作信息及模型信息进行存储。最终实现三维场景的实时漫游、背景音乐的切换、室内光影效果展示、模型的删减、模型贴图的动态更换、场景截图等功能。该系统实现了友好的模拟操作接口和人机交互界面,增加了用户的沉浸感,更大程度地满足了用户的需求。

Research and Application of Indoor Simulation Operating System Based on Virtual Reality

With the increasing demand for living environment and home design industry,traditional design drawings cannot let users feel the decoration effect intuitively which often cannot make users satisfied.Based on virtual reality technology,the simulation operating system of indoor home is studied,the 3d home model is designed and produced,and the skeleton animation of virtual character is studied and produced.In the process of system design,grid modeling,Biped skeleton key frame technology,automatic path-finding detection algorithm,role manager call,collision detection technology and ray detection technology are fully integrated,and the Oracle database and SQLite database are used to store user operation information and model information.Finally,it can realize real-time walkthrough of threedimensional scene,background music switching,indoor lighting effect display,model deletion,model mapping dynamic replacement,scene screenshots.The system realizes friendly simulation operation interface and human-computer interaction interface,increases user's immersion and meets customer's needs to a greater extent.
