Retrieve 3D dynamic images with WebGL three-dimensional visualization technology

Big Data visualization platform is a three-dimensional presentation technology to represent complex information, to achieve the stereoscopic presentation of massive data. With the help of visual thinking ability of human brain, visualization technology can summarize some related visual data by mining the important relationship between data to reveal the hidden laws and trends in data, thus improve the efficiency of data usage.
On the basis of solving the problems of large-scale data analysis time-consuming, insufficient digging depth and simple data presentation, the Big Data visualization platform makes people no longer limited to using traditional relational data tables to analyze data information, but presents and deduces the logical relationship between data in a more intuitive way. In a word, data visualization is a very important means of big data analysis.
The WEBGL raster data rendering engine, based on GPU rendering, is the most efficient parallel core component of thousands, with an advantage in image processing rendering. The browser is becoming more and more perfect for WebGL, and WebGL is based on GPU rendering technology that supports dynamic rendering of massive amounts of data.
In the visual rendering of large quantities of remote sensing, meteorological and other data, we chose WEBGL technology to satisfy the operation of raster data. At the same time raster data, these lattice data, in the data statistics is more than the million two-dimensional matrix of the operation analysis, the use of WebGL GPGPU Universal GPU computing function statistical operations.

Internet with its convenient, fast and modern features, is becoming the most important way for people to obtain information, 2D pages no longer meet the needs of people, 3D pages have become the trend of the future.
Through a higher level of data analysis, mining data behind the potential value of the application, with the help of WebGL three-dimensional visualization technology, the image of an intuitive 3D dynamic image to retrieve information, improve the user experience.
Traditional Web3D solutions rely primarily on FLASH,JAVA3D and Microsoft's Silverlight technologies. However, there is a common flaw in the above technologies, which makes it difficult to support web-side GPU acceleration, making it difficult to render large-scale complex 3D scenes. The advent of WEBGL solves this problem, and WebGL is a 3D drafting standard, By combining JavaScript and OpenGLES2.0 to provide an OpenGL-like API and providing 3D accelerated rendering on the web, it perfectly solves the two issues of Web interactive three-dimensional animations that are now dependent on plug-ins and do not support GPU acceleration.
Three.js is a webgl third-party library written by JavaScript that provides a lot of 3D display functionality. The three.js is a 3D engine running in a browser that can be used to create a variety of three-dimensional scenes, including cameras, lighting, renderers, materials, and other objects, making it easy to create 3D motion pictures.
Visualization is the technology that uses computer graphics and graphics processing technology to transform data into graphics or images. Presentation of visual data information through the client and server, the client makes a request through the model framework, the model framework to determine the user click event, the HTTP protocol to the server to make a request. The server receives the request information to be processed by the SSH framework, the framework accesses the data to the database, and then returns the data to the client, the client populates the data into the model, and the data-populated model is rendered by the browser that supports HTML5.

Our most common or used Webgis system is Google Map, Baidu Map and other maps system, the technical development of these systems also embodies the entire Webgis technology development direction.
In various industries Webgis application Data complexity is more complex than the popular map application, in agriculture, Water Conservancy, transportation, land industry and other fields have their own unique data types, data analysis models, these applications are gradually converted from CS to BS architecture better service to the public users.
