Research And Application Of The Reuse Oriented Digital Shadow Perform Platform Core Technology

This paper is based on the results of the early digital shadow research, furtherstudy the common problems of the digital shadow show platform. Using designpatterns, software reuse and other related technology simplifies the digital shadowshow platform fabrication process, and the shadow puppet performance platformrelated functions are improved. Mainly includes the following three parts:1) research on the digital shadow interactive control. Multi point touchtechnology is the most important and feasible way of a digital shadow showperforming. Adding touch control code to the digital shadow model in different parts(head, hand, upper limb, lower limb, body) follows the same steps, the steps andrelated parameters are separated, and the structure of the control code were redesigned.Using the software reuse technology package the redesigned code, and generatingreusable code file. If the developers of digital shadow show platform import thereusable code file, they can implement the digital shadow model control by writting alittle code passing the corresponding parameters.2) research on the digital shadow network performance technology. Research onlayout and design department has a good number of shadow generation for shadowperformer through the network for performing version. Using client/serverarchitecture from the software on the network version of the digital shadow showplatform design, the server using red5streaming media server, network functionindependent digital shadow show platform to other functions, and can be generatedfor different digital Shadowgraph use the class file, related technology and code canbe reused.3) based on XML file digital animation recording and playback technology.Using the event mechanism to monitor user interactive operation and, according to theevent object and analyzing the users of those operations, and the definition of theXML files are stored in the data format and content, will be the user interaction datastored in the XML file. The playback process on how to load and analytic recordgenerated XML files, and study how to according to the recorded data automaticallytrigger events.Finally, the application of technology in digital Shadowgraph production process,experimental results show that this technique can simplify the production process ofdigital Shadowgraph, convenient digital Shadowgraph performance, and to the userfor performing process for recording and playback.
