基于Web的2.5维校园地图的设计与实现

The Design and Implementation of 2.5 Dimensional Campus Map Based on Web

随着数字城市建设的不断推进,二三维电子地图逐步成为校园信息化建设的重要组成部分。本设计旨在开发2.5维校园电子地图,更真实的展现校园景观,用于学校宣传展示、校园布局介绍等方面。研究方法是以天津科技大学为例,首先根据校园地形信息生成二维地形图,并进行底图处理及区域划分。再利用3ds Max实现三维虚拟场景,通过添加纹理及贴图,按特定的俯视角度渲染生成2.5维的校园空间平面地图。通过HTML和Java Script语言对网页进行制作并利用IIS发布,最终实现基于网页的校园地图。本设计利用虚拟现实技术展现出更加立体化、真实化的校园结构,较三维地图而言,具有简单直观、数据量小、后台运行速度快的特点。此外,通过校园网快速浏览,为用户提供了一个具有交互性的数字校园展示平台。

With the continuous advance of digital city construction, two or three dimensional electronic map has gradually become an important part of campus information construction.This design is the production of a 2.5D campus electronic map system, it can show the more realistic campus landscape, and be used for school publicity show, information presentation etc. The research method is take a certain university as a case, first of all, according to the terrain information of campus it should generate 2D topographic map and plot processing and regional division. After that, it should produce 3D scene modeling and add texture and texture by 3ds Max. It need to generate 2.5D the campus space plane map with the particular view angle. Web pages uses HTML and Java Script language and releases by IIS.With virtual reality technology, this design show campus structure more vivid. Compared with a 3D map, this design has the characteristics of simple and intuitive, less amount of data, faster background running speed. In addition, the user has interactive platform of a digital campus through the campus network.
