【摘要】 粒子系统是描述自然现象及其他过程式模型的有效方法,目前已在可视化仿真中得到广泛的应用。针对目前粒子系统算法研究分散的现状,利用通用的算法和面向对象的结构设计方法和随机纹理控制的方法,开发了一种可视化粒子编辑系统。该系统不仅可以实现多种特殊效果,而且可以完成其他建模软件难以实现的过程式模型。简述了系统的基本功能及粒子系统的基本原理,论述了系统的设计与实现过程,讨论了利用该系统开发一个过程式模型的基本过程及面向对象的系统结构设计方法,给出了该系统实现的一些典型效果截图。更多还原

【Abstract】 Particle system is an effective and widely used method to describe natural phenomenon and other process model in visualization simulation, but there is relatively little research and discussion on a common algorithm and common system can integrate specific use particle systems and specific particle algorithms. A powerful and convenient visual particle editing system with object oriented design method and random texture mapping technology was developed to solve this problem. Based on this system, many special effects and process model that other modeling software cannot be conveniently given could be easily developed. The basic function of this system and the principle of particle system were introduced. The designing and implementation process of this system, the system configuration and object oriented developing method was discussed. Some typical effect picture of the system’s application was given.更多还原
