Recently graphic hardwares have been developed remarkably, and domestic and foreign game users have demanded realistic and spectacular game graphics. Graphic special effects are one of methods to satisfy these requests, but we have not known any cases where graphic special effects are general and thus reusable. Based on the implementation of our graphic special effect engine and its application cases, this paper describes how to easily exploit graphic special effects in developing games. We define a standard file format in which special effect data can be saved and loaded, and thus those data can be reused easily. We also show that developers can test or preview special effects by exploiting our graphic special effect tool even before producing games.
