摘要:
对于天气现象的模拟在许多领域有广泛的运用,例如对云雾、雨电、风雪、海浪等自然场景的模拟,对这些自然场景的真实性的提升十分重要。 其中雨的模拟仿真包括了对雨滴粒子的形状、大小、轴比、取向( 又称倾角茁) 等微物理特征的描述。 天气雷达强度受雨滴倾角影响较大,因此雨滴倾角是天气雷达测量精确度的重要影响因子。 文中通过研究雨滴的物理特性及其运动过程,得出了雨滴倾角与雨滴大小成反比,与风力大小成正比的结论。 在 Unity3D 引擎中使用粒子系统模拟雨滴降落过程中受风力影响产生倾角。 提出了联动了雨滴大小与风力的方法,结合图形用户界面,经实验实现了动态模拟不同雨滴大小与风力下的雨滴倾角动态变化。
Abstract:
The simulation of weather phenomena is widely used in many fields,such as the simulation of natural scenes such as fog,rain,snow,waves and so on,which is quite important to enhance the authenticity of these natural scenes. The simulation of rain includes the description of the shape,size,axial ratio,orientation (also known as dip angle) of raindrop particles. The intensity of weather radar is greatly affected by the angle of raindrops,so the angle of raindrops is an important factor affecting the accuracy of weather radar measurement. By studying the physical characteristics and motion process of raindrops,the conclusion is drawn that the angle? of raindrops is inversely proportional to the size of raindrops and proportional to the size of wind. In Unity 3D engine,the particle system is used to simulate the angle of raindrop due to the influence of wind. The method of linkage between raindrop size and wind force is proposed.Combined with the graphical user interface,the dynamic simulation of raindrop inclination under different raindrop sizes and wind forces is realized through experiments.
