The particle system is an effective method to realize the effect of the fountain, but This method can reduce the real time of virtual reality system due to the large number of triangular element drawing. Vector control method is adopted to construct this method The vertical particle system fountain model is then rendered as a continuous image of a certain number, which is used as a map and the billboard is adopted The technique and dynamic texture technique realize the drawing of the texture fountain, which guarantees the real sense of the system and improves the real-time performance of the system.

To maintain the immersion and real_time characteristic of the system, vector con - Trol method is programs to create fountain model -based on particle system, and then a series of textures Are rendered, finally, combined with billboard and dynamic texture technologies, texture fountain is Achieved.
