Study on General Model of Special Effect Simulation

摘要

Warfare simulation needs to render a realistic virtual 3D battlefield environment efficiently to ensure the authenticity and real-time interaction. However, modeling special phenomena which are common in battlefield environment has proved difficult with the existing techniques of computer graphics. A method for special effect modeling and simulation by using particle system is proposed. Based on detailed discussion on the theory of particle system, the general particle system model for special effect simulation is designed, and its concrete implementation is presented. By capturing common features of various effects and carefully structuring into the model composition, the model can he reuse in different effects simulation with little modification, making it an efficient way to create various convincing special effects in virtual battlefield environment. With its flexibility, the model is easy to manipulate and implement. Its Level of Detail can be easily adjusted. Finally, concrete special effects simulation examples by using the model are also given to test its efficiency.
