三维虚拟校园漫游系统中的角色建模与行为控制
|
摘要
目前各个高校信息化建设的主要内容是建设数字化校园,且各个高校软硬件综合实力主要体现在三维虚拟校园漫游系统的建设和开发上。文中研究三维虚拟校园漫游系统中的角色建模和行为控制过程,以期创建出更好的三维虚拟校园漫游系统。采用基于数字摄影测量技术三维建模方法,构建单一建筑三维角色模型,将多个单一建筑模型合拼调整,并加入环境要素和其他要素,获取总体虚拟校园角色模型。通过交互漫游、提示角色信息、碰撞检测实现对角色的行为控制。实验结果表明,所提方法建立的角色模型纹理数较多、清晰度高、运行速度快,且平均碰撞检测时间低于19.8 ms,为浏览者提供更为清晰、流畅的可视化三维虚拟校园漫游平台。
At present,the main content of informatization construction in colleges and universities is to build digital campus,and the comprehensive software and hardware strength of colleges and universities is mainly reflected in the construction and development of the 3 D virtual campus roaming system. The processes of role modeling and behavior control in the 3 D virtual campus roaming system are researched in this paper,so as to create a better 3 D virtual campus roaming system. The 3 D modelling method based on the digital photogrammetry technology is adopted to construct a single 3 D-role building model. Multiple single building models are combined and adjusted with the environmental element and other elements added,so as to obtain an overall virtual campus role model. The role behavior control is realized by means of interactive roaming,role information prompt and collision detection. The experimental results show that the role model built using the method proposed in this paper has many textures,high clarity,fast running speed,and the average collision detection time of less than 19.8 ms,which can provide a clear and smooth visual 3 D virtual campus roaming platform for browsers.
