摘要
烟雾是普遍存在的自然现象.影视、动画、图形技术日益深入发展,各个领域对于烟雾的真实模拟已不可或缺.模拟需求越来越多、要求也越来越高.传统粒子系统不能满足实际需要;数学物理方法计算复杂,影响其广泛应用;基于纹理的方法越来越受到重视.本文采用基于纹理球的快速模拟方法.分析了真实的烟雾特点、运动变化等因素;设计了关键的控制变量.算法具有灵活的处理方式和开放的可扩展性.最后给出了实际的模拟效果,基本能够达到实时性要求.
Smoke is a common and natural phenomenon.With the increasing development of film,animation and graphic technology,real-time smoke simulation has become indispensable in various fields.More simulations are needed at a higher standard.The traditional particle system method has not been able to meet such practical demands;the computational complexity of mathematics and physics affects its w ide application;the texture method has attracted more and more attention.This paper adopts the fast smoke simulation method of texture sphere.In this paper;it analyzes the real smoke movement characteristics,changes and other factors and designs the key control parameters.The algorithm has a more flexible approach and a certain degree of extensibility.Finally,this paper presents the actual simulation results so as to meet the real-time requirements.
