用粒子系统显示三维旋动射流

Visualization of 3D Swirling Jets by Particle System

粒子系统提供了一种从相当简捷的抽象描述中产生复杂结构的方法，可以产生传统的由面构成的物体难以产生的动态和“模糊”效果．笔者借助于粒子系统的这一特性，动态地显示旋动射流复杂的过程，将有助于更加深入地理解旋动射流的特性．结果表明粒子系统是显示三维旋动射流的一种较为有效的手段．

The particle system provides a method for the creation of complexstructure from a relatively brief abstract description.They can be used to produce dynamic and 'fuzzy' effects that are difficult to achieve with traditional objects made of surfaces. Helped with the properties of particle system,the papershows the complex process of swirling jets dynamically. Visualization of 3Dswirling jets is helpful to synthesize its properties profoundly.The results showthat particle system is an excellent means to visualize 3D swirling jets.
