DirectDraw在实时显示中的应用

Application of DirectDraw to real time display

ＤｉｒｅｃｔＤｒａｗ是Ｍｉｃｒｏｓｏｆｔ公司发行的软件开发工具包，由于它能产生快速、平稳的图形，而被广泛地应用于游戏软件的开发制作中。同样，我们利用其显示速度的优越性，扩展 ＤｉｒｅｃｔＤｒａｗ在其他领域的应用。文章介绍了ＤｉｒｅｃｔＤｒａｗ软件开发工具包在 ＧＹＺ４０００型遥测地震仪微震监视模块中的应用。利用 ＤｉｒｅｃｔＤｒａｗ，实现了野外地震数据的无闪烁、平稳、高速显示。

DirectDraw is a software development tool kit, and released by Microsoft. Because it can bring fast and smooth display effect, then be widely applied to develop software on games. In the same way,we can make use of the advantage on the way of display velocity of DirectDraw, and extend its application to other domains. The paper generally describes the DirectDraw software development tool kit and how to use it in the real monitor model of GYZ4000 remote seismic data acquisition system. We can use DirectDraw to realize field seismic data display smoothly and high fast, and without twinkle. Using DirectDraw is very exciting,just as Microsoft declares: 'It is good, It is fast'.
