在景观和基础设施项目规划领域，实时3D环境为航空摄影、平面图和地图等传统的场地评估方法提供了有益的补充。虚拟模型可以让用户深入了解网站的复杂性，以及网站功能之间的关系。特别是，在实际实地考察之前使用实时3D景观模型，可以在现场进行更有效的评估。近年来出现了一系列游戏开发平台，这些平台极大地促进了实时3D模型的开发。这些游戏开发平台或游戏引擎提供了对早期技术（如虚拟现实标记语言（VRML））的强大扩展。除了可重用的软件组件外，游戏引擎还提供了一套可视化开发工具。这些工具是一个集成的开发环境，可以简化、快速地开发交互模型和环境。它们主要提供强大的渲染引擎，可以实时可视化复杂、高度详细的3D景观。它们通常还提供脚本界面、物理引擎、声音、动画、人工智能和网络，从而能够开发复杂的交互性。一些流行的商业游戏引擎包括Torque引擎，Quest3d， Unity3d和Virtools。我们提出了一个新的软件应用程序（“ASPECT Studios 3D Viewer”），它是使用Virtools游戏开发平台构建的，目的是可视化数字地形模型，通常还包括建筑物和植被。该应用程序设计用于可视化高达约100平方公里的区域。除了导航系统外，该应用程序还为用户提供了以各种方式分析模型以及修改和维护模型的工具。因此，最好将3D查看器本身视为一组独立于模型或内容的交互工具。该应用程序是在一个成熟的景观建筑工作室内制作的，以响应工业的需求。它特别针对政府部门所提供的标书的要求。景观设计师和城市规划者使用3D Viewer来帮助解决规划问题，特别是视觉评估问题。它发现了城市地区模型的最广泛应用，尽管它已用于农村地区。
In the field of landscape and infrastructure project planning, real-time 3D environments provide a useful complement to traditional methods of site assessment such as aerial photography, plans and maps. A virtual model gives the user an insight into the intricacies of the site and how site features relate to each other. In particular, use of a real-time 3D model of the landscape prior to an actual site visit enables a much more efficient assessment while in the field. Recent years have seen the release of a range of game development platforms that greatly facilitate the development of real-time 3D models. These game development platforms or game engines offer great extensions over earlier technologies such as Virtual Reality Mark-up Language (VRML). Game engines provide a suite of visual development tools in addition to reusable software components. These tools are an integrated development environment to enable simplified, rapid development of interactive models and environments. They primarily provide powerful render engines that allow the visualisation of complex, highly detailed landscapes in 3D in real-time. They also typically provide a scripting interface, physics engine, sound, animation, artificial intelligence, and networking, which enable the development of sophisticated interactivity. Some popular commercial game engines include the Torque engine, Quest3d, Unity3d and Virtools. We present a new software application (‘ASPECT Studios 3D Viewer’) which was built using the Virtools game development platform for the purpose of visualising digital terrain models and typically also incorporating buildings and vegetation. The application is designed for visualising areas up to approximately to 100 km2. As well as a navigation system, the application also provides tools for the user to analyse the model in various ways as well as modify and maintain the model. Thus the 3D Viewer itself is best thought of as a set of interactivity tools independent of the model, or content. The application was produced within an established landscape architecture studio in a response to the needs of industry. It particularly addresses the requirements of tenders offered by government departments. The 3D Viewer is used by landscape architects and urban planners to help resolve planning issues, in particular visual assessment issues. It has found widest applications for models of urban areas, although it has been used for rural areas.
