With the popularity of the Internet,online advertising industry has made rapid progress. In-game advertising becomes a new form of online advertising. Due to the large number of the players,the media value of online game is growing,and the related in-game advertising integration technology has gained some progress. Current in-game advertising technology uses SDK integration approach and needs to modify a lot of source codes of games. This integration technology is high coupling between the advertising logic and the game logic, therefore it is difficult to implement complex interactive advertisement. This paper proposes an in-game advertising integration technology based on function interception to overcome the deficiency of existing SDK advertising integration technology. The technology presented in this paper intercepts and displaces 3-D graphics rendering functions,dynamically executes scripts program,it integrates image, video,3-D object and interactive clicking advertisement into game scenes without modifying the source code of game client. Experimental results show that it does not affect the fluency of the online game after integrating advertisement in online game scenes by function interception, and the game scene keeps high refreshing frame rates.%伴随互联网的普及,互联网广告得到快速发展,游戏内置广告已成为一种新兴的互联网广告形式.由于玩家数量庞大,网络游戏的媒体价值不断增长,与其相关的广告集成技术也获得一定发展.现有游戏内置广告技术采用SDK的集成方式,需要大量修改网络游戏源代码,广告逻辑与游戏逻辑耦合度高,难以实现复杂的交互式广告.提出一种基于函数截获的游戏内置广告集成技术,克服现有SDK广告集成技术的不足.该技术截获并替换三维图形绘制函数,动态执行脚本[¨]程序,在不修改游戏客户端源代码的情况下,集成图像、视频、三维物体和动态交互式点击广告.实验结果表明,应用该技术在网络游戏场景中集成广告,不影响游戏运行的流畅性,游戏画面仍保持较高的刷新帧率.
