Design And Implementation Of 3D Geological Model Visualization System Based On Web

After decades of rapid development,Internet technology has entered a new era of Internet.Many traditional industries began to actively seek the organic combination with computer network information technology,so as to make the development of their own industry in line with the overall development direction of the times.Computer technology services and communication technology services,is to achieve "Digital Earth","transparent underground" one of the main support services technology.Geospatial information science and technology is composed of three-dimensional geological model,visualization technology and other related disciplines.With the continuous popularization of Internet technology in the 21 st century,the application of web technology is more and more widely,the scale of application is also constantly improving,and its technical means are more and more tending to be highly complex.With the help of web-based 3D model and visualization technology,this paper develops a set of 3D geological model system which can be operated interactively on the web platform.It will provide high-quality 3D model display,prediction,learning and other functions for urban planning,environmental protection,scientific research and popular science education.On the basis of previous scholars' theoretical knowledge of 3D geological model visualization based on Web,this paper summarizes and further studies the development status of 3D geological model at home and abroad,the visualization technology and methods of 3D geological model on Web,and realizes the visualization results of 3D geological model on Web.First of all,the front-end page uses HTML5 technology to build the basic login page and website home page.Then the webgl technology based on three.js architecture is used to realize the visualization of 3D geological model,which can basically realize the rotation,size transformation,cutting and other different functions of 3D geological model on the web page.Finally,the API interface of Baidu map is used to realize the basic base map of 2D data display,which makes 2D geological data easy for users to view and browse.
