基于Cesium的传统建筑虚拟交互场景构建关键技术研究

Research on Key Technologies of Traditional Buildings Virtual Interactive Scene Construction Based on Cesium

本文以传统建筑倾斜三维模型为基础数据,以WebGL为绘图技术标准,基于Cesium技术,研究了OSGB、OBJ、3DS等与3D Tiles的数据格式转换、三维模型与影像及文字属性信息的展示与编辑、场景对象动态单体化、融合Web技术建设传统建筑场景三维可视化交互平台等关键技术,构建了某传统建筑街区虚拟交互场景,为我国传统建筑街区虚拟交互场景的展示和管理提供了技术支撑和方法借鉴。

This paper takes the tilt 3D model of traditional buildings as the basic data,WebGL as the drawing technology standard,Cesium as method,to study the data format conversion between OSGB,OBJ,3DS,etc.and 3D Tiles,and to explore key technologies including the display and editing of 3D model,image and text attribute,the dynamic seperation of objects,and the construction of traditional architecture 3D visualization interactive platform coupled Web technology.A virtual interactive scene of a traditional building block is constructed,which provides technical support and methodological reference for the display and management in the field.
