基于虚拟现实的室内布局系统及碰撞检测算法研究

The Interior Layout System and Research of Collision Detection Algorithm Based on Virtual Reality

虚拟现实技术是融合了计算机图形学、多媒体技术、智能人机接口技术及传感器技术的一门交叉技术。与三维静态模型相比,它增加了交互性,给系统用户带来完全的沉浸感和想象空间。根据室内装修行业的发展需要,其建立了基于VRML语言的网页三维实时漫游系统,通过AABB碰撞检测算法对区域精确检测的改进,实现了对算法储存空间的节省和运行速度的提升。该文阐述了场景构建、模型生成及碰撞优化技术,涉及了本虚拟现实系统中技术的研究内容和方向。

Virtual reality is a cross technology which is the integration of computer graphics, multimedia technology, intelligent manmachine interface technology, the sensor technology and so on. Compared with the static 3D models, it increased the interactivity, and a user of the system has completely immersed sense and imagination. According to the need of the development of interior decoration industry, we establish the system which is based on Web 3D real-time walkthrough of Virtual Reality Modeling Language（VRML）.By the improvement of AABB collision detection algorithm for accurate detection of regional, this system realizes the save of storage space and enhances the operating speed up. This paper describes the scene construction, model generation and collision optimization, which connect with the research content and direction in the virtual reality system.
