基于粒子系统的自然景物模拟研究

对自然景物的模拟在视景仿真系统、计算机游戏、三维动画中有着广泛的运用。粒子系统是模拟是自然景物的有效方法。以往主要运用粒子系统方法针对某种具体的自然景物现象进行模拟，本文结合面向对象思想，将粒子系统的相关属性和功能进行封装，开发一套通用的程序接口，并采用OpenGL渲染引擎，系统具有较好的灵活性和可扩展性，使之能够满足在普通PC机上模拟不同自然景物的需求。

Research on the Natural Phenomenon Simulation based on Particle System

The effect of natural phenomenon simulation has been widely used in visual simulation system, computer game, and 3D animation and so on. Particle system is an effective method in natural phenomenon simulation. In the past, the main aim of particle system is for some specific natural phenomenon. In this paper, making using of object-oriented method, a common set of APIs has been developed with the package of some related properties and functions in particle system. At the same time, the use of OpenGL rendering engine makes the simulation system with good flexibility and scalability and can meet the need for different natural phenomenon simulation in ordinary PC machine.
