| In the face of massive data growth,In the face of massive data growth,the traditional meteorological data software hardly to meet the needs of complex data visualization,and the problems of slowly loading,poor interaction are emerging gradually.With the development of Internet and Visualization technology,researchers begin to try to solve the mass from the new angle of Web visualization to display the mass and pluralism meteorological data,Therefore how to efficiently implement the Web visualization of meteorological data visualization is an important research topic.Aiming at the shortcomings of traditional meteorological data platform,we mainly study the related technology of Web visualization and algorithm theory in this paper.Mainly we focus on the Web visualization technology and algorithm of two-dimensional and three-dimensional visualization,and provide a theoretical basis for the realization of the following Web visualization system.On the basis of the research on the visualization technology of Web based on particle system,we put forward some improved algorithms and a multivariate data visualization method about mass data,and realizing the data visualization system of atmosphere data.The main work is organized as follows.(1)According to the shortcomings of the traditional particle visualization,we propose particle life control algorithm based on an interference factor param,which can improve the response speed and enrich the visualization of the Web page.(2)Due to the limited computing resources of Web browser,we propose a vector field interpolation algorithm,and pre-process the algorithm of updating the particle position before rendering the Web canvas.(3)This paper we propose a data visualization algorithm based on particle simulation,and apply this method to 2D and 3D visualization system.The two-dimensional particle visualization is mainly based on canvas technology;the 3D visualization system is based on QTEK framework which encapsulates some WebGL API and WebGL shader language which makes the Web application efficient.(4)Combined all methods above,we develop a Web based on 2D and 3D atmospheric data visualization system which achieve good results. |
