增加的典型方法

代码说明：

The typical approach to adding in-game media such as movies and television has been to cycle through a series of textures. In order to play even a short show meant that a lot of texture swapping and memory had to be used, so the idea was to replace this method with a MPEG decoder and display each pixel as a polygon. I believe this is the first example of this method for two main reasons, firstly it takes a lot of processing to read the frames and display the large number of polygons but this is no longer a problem with the latest video cards, and secondly, it is no picnic writing a MPEG decoder. Fortunately I didn t have to write the MPEG decoder, I have used and modified the freely available source code ported to Win32 by Thanassis Tsiodras which was originally released by the University of California in 1992, back when there was a greater open source ethic.
