摘　　要：粒子系统是迄今为止模拟不规则模糊物体最为成功的一种图形生成算法。针对数字高清字幕机字幕制作实时性强、图文意义表达充分、操作简单等特点,引入纹理映射、粒子运动控制、颜色表查询等多种方法对传统粒子算法加以改进。结果表明,改进的粒子系统方法丰富了高清字幕机的字幕制作,产生了理想的图文效果。　The particle system is a successful methods for simulating anomalous and fuzzy object.Concerning the real-time characteristic,the meaning express and the simply operation of the digital high-definition title generator this paper presents the method such as texture mapping,particle movement control,color inquire to improve the tradition algorithm of particle system.According to the result of experiment,the improved algorithm enriches the title generation of the digital high-definition title generator,obtains perfect image effect.
