| 摘 要： | 讨论了交互式生成3D地形的应用背景和必需解决的技术问题。着重分析了地形数据点的三维拾取,实现了在三维场景中通过鼠标点击修改地形高程值。以此为基础,设计并实现了一个基于VRML的交互式三维地形生成系统。用户可以在缺少实测数据的情况下,根据系统提供的各种交互工具快速方便地生成与自己观察或印象相符的三维地形。在房地产广告、军用沙盘、旅游景点展示、工程招投标等方面有广泛的应用价值。 |

| Abstract: | The technology problem need-resolved and application background of interactive 3D terrain building was discussed. The forces were analyzed that the terrain data point was picked up, and terrain elevation value was modified with the clicking of mouse in the 3D scene. Based on them, a system of interactive 3D terrain building was designed and implemented based on VRML. User can build 3D terrain quickly using the interactive tools provided by the system, under the circumstance of lacking true data. This technology has broad application value in real estate advertising, military sand table, showing tourist attractions, such as the bidding project. |
