摘　　要：提出了一种实现SlideShow中effect和transition的新方法,即基于GPU的实现方式。论述如何充分发挥GPU的功能,用Direct3D实现SlideShow中的effect和transition。利用Direct3D中的固定功能流水线能实现多种transition和一些简单的effect,如扫描、渐隐渐现及图像旋转等。借助Direct3D中的可编程流水线功能则可实现多种effect,如浮雕、马赛克等。论述了使用高级渲染语言实现多种特效的方法,并给出了编程示例。This paper proposed a new method of implementing effects and transitions in SlideShow, which was based on GPU （ graphics processing unit ）. It discussed how to take advantage of GPU, implement effects and transitions in SlideShow using Direct3D. With the fixed function pipeline, could implement many transitions and some simple effects, such as wipe in/wipe out, fade in/fade out and rotate image. With the programmable function pipeline, we can implement much more effects, such as emboss and mosaic. Discussed using the high-level shader language to implement effects. And also gave some examples about effects and transitions.
