Abstract: 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.

Key words: particle system, digital high-definition title generator, texture mapping, particle movement control
