摘要
Multigen-Paradigm Vega是最出色的三维视景仿真软件之一,为了给使用该软件的系统开发人员提供开发参考,以小镇虚拟漫游系统为例,详细阐述了采用Vega进行系统开发的详细过程。首先对Vega及其升级版本Vega Prime进行了简单的介绍,在此基础上,介绍了虚拟小镇漫游系统的详细设计,其中包括添加对象模型、设置碰撞检测、观察者定位及多观察者设置、设定浮云、日出及昼夜更替等环境效果和画中画效果等。通过以上设计,实现了虚拟小镇漫游系统。在此基础上,针对该系统的缺点,文章最后对未来的工作和需要改进的地方进行了介绍,如添加声音、利用DI-GUY添加人物、更强的碰撞检测、仪表显示、指定路径漫游等。文中采用的系统开发方法对虚拟系统人员具有一定的借鉴意义。
Multigen-Paradigm Vega is one of the most outstanding three dimension visual simulation software.In order to provide system developers with some reference,the virtual town tour roaming system is taken as an example,and the developing progress of the roaming system is elaborated.Firstly,Vega and its updated version Vega Prime is introduced in brief.Second,on this basis,the developing progress of the virtual town roaming system is described in detail,including adding object model,setting the collision detection,observer localization and multi-observer settings,setting the clouds,sunrise and night change and other environmental effects.Through the above design,the virtual town roaming system is implemented.Lastly,aiming to the system shortcomings,describe the open problems and future work,such as adding sound and characters using DI-GUY,more accurate collision detection,showing instrumentation,specifying the path while roaming and so on.Virtual system developing person can use the system development method used in this paper for reference.
