利用三维数字化建筑场景，模拟和感受城市建筑生活环境，多角度、真实性地再现了未来城市设计，相比传统 的图纸规划，不仅节省了人力，而且有效提高了城市规划的准确度。本文设计了一种三维数字化城市漫游系统，将实时交互和 虚拟体验结合起来，可以让城市规划部门通过虚拟体验后完成城市建设的规划。通过三维数字化城市设计为人类带来逼真城 市漫游体验。

The three-dimensional digital construction scene is used to simulate and feel the urban living environment construction, recreating the future urban design from multiple perspectives with authenticity, which not only saves the manpower, but also effectively improve the accuracy of the urban planning compared with the traditional drawing submissions. In this paper, a three-dimensional digitized urban roaming system is designed to integrate real-time interaction and virtual experience, so that the urban planning departments can complete urban construction planning through virtual experience. According to the three-dimensional digitized city design, the harmony between human and urban environment can be achieved, bringing the living experience of urban roaming to human beings in virtual environment.
