Design and Implementation of Three Dimensional Virtual Roaming System for Modern Park

For the practical requirement of digital park design, this paper comprehensively explores technological difficulties of three dimensional modern park in detail. In the process of specific analysis and research, it mainly further optimizes and improves related models to introduce multi-detailed hierarchy technology to models. During system development, scripting module which is offered by Virtools designs and realizes virtual roaming modes of automatic roaming and manual roaming. Meanwhile, it elaborates some key technologies to realize animation and roaming in VRP. Test analysis shows that virtual park in this paper is perfect in reality sense and scene demonstration is fast so it is convenient for users and scenes to interactively operate in order to assist further 3D parks construction in cities.
