Studies on the application of particle system in the virtual battlefield situation expression
During the expressed of the virtual battlefield situation, a lot of irregular objects have to be simulated. Particle system is an effect way for the modeling of fuzzy object, which need dynamic modeling. We expatiate on the application of the particle system from the aspect of tactics situation express and from two aspects: combat entity simulation and environment entity simulation, and analyzing the optimize method of the particle system from Particle reuse, Frustum, Billboard and Texture Mapping, LOD. Finally, we design and establish an antitype system with the design pattern, which verify the result of the research.
