摘要
基于SketchUp三维建模软件及ArcEngine组件在.NET开发环境下设计开发了一个集高效三维地形构建与三维模型可视化于一体的三维交互漫游系统。以某校园的三维建模及三维展现为例,详细介绍了基于ArcEngine的三维交互漫游系统总体结构和功能实现中的技术问题。该系统实现了三维地形和三维建筑模型的快速构建及渲染、二维GIS与三维GIS功能融合、二三维场景的互动立体浏览和空间分析等功能,增强了三维交互的真实感和空间分析能力,为三维交互漫游提供了一个高交互感的平台。
Based on the 3D modeling software SketchUp and the ArcEngine component,a 3D interactive system which in- tegrates 3D model visuaIization and efficient construction of 3D terrain is developed under the net-based environment. Take a 3D modeling of the campus with 3D display as an example,the overall structure and technical problems of interactive roaming system based on ArcEngine in 313scene are introduced in detail.The system realizes many functions, such as fast construction and rendering of 3D terrain,fast construction and rendering of 3D building model,integration of 2D GIS and 3D GIS function,3D scene interaction,spatial analysis and so on.This system enhances the spatial analysis ability and the sense of reality of 3D interaction and provides an interaction and collaboration platform for 3D interactive roaming.
