| With the arrival of the era of big data,information technology has developed quickly in many industries,like politics,economy,military and so on.Therefore,how to extract and display effective information from massive information has become a research hotspot in many industries.Data visualization is a visual presentation of data sets,which can transfer the value of information effectively.The problems of traditional visualization applications are:(1)Lacking high-performance support for a flexible construction of three-dimensional views.(2)Lacking mature product design of building visualization large screens and the support of further application for completed visualization large screens.(3)Most applications have high thr-eshold and poor versatility,which are aiming at professional researchers.In view of the above problems,this topic focuses on the analysis and resear-ch of data visualization technology and large-screen visualization technology.The main research contents are as follows:(1)Propose and implement three-dimensional visualization tool TDDVL based on WebGL,which solves the problems of complicated data conversion and inflexible management of three-dimensional layers in current visualization,and enables users to analyze data visually and construct three-dimensional views flexibly.In addition,WebGL teclenology is used to ensure that the three-dimensional data visualization tool achieves plug-in-free,fast rendering speed,support mobile end and other high-performance effects.(2)Define the process of visualization large screen construction.And implement a system which provides integrated services including reading multi-source data,generating three-dimensional views,building visualization large screens and large-screen functional applications.(3)Design and implement a 3D data visualization large-screen system based on WebGL.The system can support multi-source data connections conveniently and construct artistic three-dimensional visualization views efficiently.At the same time,this system realizes real-time large screen,large-screen carousel and large-screen embedding.The system has been tested in both function and performance,which ensures high robustness and reliability of the system.This paper designs and implements a three-dimensional data visualization large-screen system based on WebGL.It combines related technology research with application scenarios to realize convenient and flexible visualization application.The system supports a variety of data source connection modes and provides users with flexible and efficient three-dimensional visualization construction services.At the same time,users can build and use a visualization large screen easily and quickly through the system.The system performs well in various industries. |
