Research Of Multi Screen Splicing System And Its Key Technology Based On Windows Presentation Foundation

Windows Presentation Foundation (WPF) platform is Microsoft.NET platform,the latest version of the current4.5, most new computer software version, the bottominterface is Direct X, and the resulting image vector is a series of rendering engine,compared with GDI/GDI+programming model of a generation ago, have made greatprogress.At the same time, the Internet of things technology is constantly advancingdevelopment, plays a key role in many real life. Single screen is obviously difficult tomeet the multi information display, must use the multi screen splicing technology, theconstruction of large screen display information architecture. But the absence of theman-machine interactive way scientific, difficult to let users full access to information.Therefore, how will the multi screen splicing, makes a lot of information in the wholesystem in a convenient, multidimensional mode of operation by the user to obtain, is akey issue in this field.In this paper, based on the basis of WPF, according to the analysis ofhuman-computer interaction research of large screen environment of IOT, analysis oftheory and application related, interactive way of efficient technique using multi touchon the big screen, which can realize multi screen splicing technology and itsapplication. The main contents of this paper are divided into the following aspects:Firstly, this paper researches on two crucial technologies of multi screen splicingsystem based on WPF. The one is screen splicing technology, based on WPF throughthe experiment, matching of the multi screen splicing, and reoutput to the outputdisplay the specified. Another is a touch control technology based on WPF, throughthe study of the touch event based on WPF, and realize the touch control environmentwith multi screen splicing system.Then, this paper researches the method of2D drawing, and the method of3Dmodel drawing，material settings and lighting setup based on WPF.This paper alsostudied the methods of translation, scaling and rotation transform by the3D model.Finally it makes the rendering multi screen splicing system interface and modelsuccessfuly.Finally, complete of a multi screen splicing large screen display system. Complete the multi touch screen system based on the time axis as the core, the systemcan be designed to run on multiple platforms,the system can touch, to control the timeaxis, click information, information display, animation, video, e-book view etc.. Thefinal realization of display system, and will show in the field of the deeper and moreextensive work provide the basis.
