Peng Yin, Jie Li, Junnan Liu · 2019
Study on realistic simulation of natural scenery has always been one of the difficult and focused problems in the field of computer graphics. In order to solve the problem of time-consuming and inaccurate simulation of particle system, this paper proposed a particle system simulation based on GPU acceleration. This method used the geometric modeling of the particle system to extract the external characteristics of the flame and analyzed the influence of two external forces of gravity and wind force. It also introduced the simplex noise to control the particle behavior, and combined texture mapping, particle collision and other technologies to make sure better realistic quality and high efficiency. Experiments testify that the method can satisfy the requirement of the reality and the real-time of fire simulation, which got more realistic simulation effect. And further improvements had been made compared with the traditional flame simulation method.
