基于开源引擎的三维场景基础平台搭建方法及实现

A method and implementation of building 3D scenes foundation platform based on open source engine

随着WebGIS技术的不断发展和三维GIS技术的兴起,3D WebGIS成为当前WebGIS发展的主流,其中三维场景基础平台可以为三维GIS面向实际应用场景提供技术支撑。本文在对常用的开源WebGL框架进行分析的基础上,使用某地区的数据,基于开源引擎Cesium.js,通过数据转换、数据编辑、瓦片生成等方法将地形数据、影像数据、倾斜模型和矢量数据处理成符合Cesium标准的格式,并通过简单的服务配置进行发布和浏览,实现了三维场景基础平台的基本浏览及量测功能,有效降低了三维场景基础平台搭建的成本。本文研究成果为三维场景基础平台搭建提供了一种兼容性、开放性与可移植性强的三维场景基础平台Web开发方法。

With the continuous development of WebGIS technology and the rise of 3D GIS technology,3D WebGIS has become the main trend of current WebGIS development,in which 3D scenes foundation piatform can provide technical support for 3D GIS to face the actual application scenarios.Based on the analysis of common open source WebGL framework and the open source engine Cesium.js,this paper adopts the data of a region to process terrain data,image data,tilt models and vector data into a format conforming to the Cesium standard through data conversion,data editing,tile generation and other methods,releases and browses through simple service configuration,realizes the basic browsing and measuring functions of 3D scenes foundation piatform,and effectively reduces the cost of building 3D scenes foundation platform.The research results of this paper provide a compatible,open and highly transplantable 3D scene foundation platform Web development method for building 3D basic scenes.
