在本文中，我们提出了一种新的导航隐喻的探索三维城市模型在虚拟环境中。所呈现的隐喻支持以类似于在真实的世界中旅行的方式在3D城市模型中进行直观的导航，而不会迷失方向。基于3D城市模型的道路网络的图形表示，计算相机路径并用于实现平滑的相机运动。我们将解释如何计算平滑的相机运动，并描述一个用户界面，可用于基于桌面以及基于投影的环境，以指定旅行目的地。
In this paper we propose a novel navigation metaphor for the exploration of 3D city models in virtual environments. The presented metaphor supports intuitive navigation without disorientation through 3D city models in a manner similar to travelling in the real world. Based on a graph representation of the road network of a 3D city model camera paths are calculated and used to enable smooth camera motion. We will explain how smooth camera motions are computed and describe a user interface usable in both desktop-based as well as projection-based environments to specify travel destinations.
