虚拟校园三维场景创建研究

Study on the creation of Three-dimensional virtual campus scene

与二维相比,三维对客观世界的表达能给人以更真实的感受,它以立体造型技术向用户展现地理空间现象,不仅能够表达空间对象间的平面关系,而且能描述和表达它们之间的垂向关系,并能对空间对象进行三维空间分析和操作。本文研究SketchUp三维模型构建和在GIS软件ArcGIS中构建三维场景。

Compared with 2D,3D give people a more realistic feel in expression of objective events, it use 3D modeling technology to show users the geospatial phenomenon, not only to express spatial relationships between objects in the plane, but also be able to describe and express the vertical relationship between them, and is able to analyze spatial objects and manipulate three- dimensional space. The paper study model construction in SketchUp and building 3D scene in ArcGIS.
