基于粒子系统的特形焰火模拟与实现

摘要

Based on the analyses of complex modeling characteristic with special fireworks,this paper puts forward a multi-parameter simulation function.Through different parameters combination,a variety of special fireworks simulation could be realized.And some special fireworks simulation was carried out using the multi-parameter function based on particle system, the results show that a variety of special fireworks simulation can be easily completed.By taking the actual scene images as background,the very good special fireworks simulation effect was obtained.%通过分析特形焰火复杂造形的特点，设计了一种特形焰火的模拟函数，通过改变参数及参数的取值实现了多种特形焰火的模拟。基于粒子系统对所设计的特形焰火函数进行了实际的模拟实验，结果表明，利用不同的参数变换可以方便地完成多种特形焰火的模拟。通过与实际场景画面的结合，得到了较好的特形焰火模拟效果。
