【摘要】：随着科学技术与计算机软硬件的飞速发展,计算机图形学在电影、游戏、广告、军事可视化仿真等方面得到了越来越广泛的应用。自然景物的模拟已经成为计算机图形学领域中最具挑战性的研究方向之一。而在自然景物的模拟中,海浪的模拟却是最为复杂的。与植物地形等景物相比较,海浪具有着随机性、动态性和不规则性,这些特性也给海浪的模拟增加了难度,也增加了对海浪模拟的挑战性。本文通过对海浪建模技术的分析与研究,在考虑到海浪模拟的实时性与真实感的基础上,决定以Fournier海浪模型为基础,通过对Fournier模型的改造,生成真实感和实时性较好的海浪模拟系统,本文完成的主要内容如下: 首先通过对前人的虚拟海浪模拟相关工作做出了分析、总结,决定选用基于几何模型的方法绘制海浪表面。其次通过对海浪形成的分析,其受到多种环境因素的影响,我们运用到其中的一些因素来控制海浪的波形,通过对各种模拟方法的研究,选定了以Fournier海浪模型这种相对较为简单的绘制方法。再次因为上述的模型不能模拟卷浪,并且在近海岸碎浪的模拟方面,研究起步也很晚,技术不是很成熟,因此,本文在利用Fournier海浪模型对海浪模拟的同时,对其进行改造,使之能产生卷浪和碎浪的模拟。最后依据面向对象的设计原则,根据本文的算法对虚拟海浪演示系统进行实现。
[Abstract]:With the rapid development of science and technology and computer software and hardware, computer graphics has been more and more widely used in film, game, advertisement, military visual simulation and so on. The simulation of natural scenery has become one of the most challenging research directions in computer graphics. In the simulation of natural scenery, the simulation of wave is the most complex. Compared with plant terrain and other scenery, waves have randomness, dynamics and irregularity. These characteristics also increase the difficulty of ocean wave simulation, and also increase the challenge of ocean wave simulation. Based on the analysis and research of wave modeling technology and considering the real time and reality of ocean wave simulation, this paper decides to transform the Fournier model based on Fournier wave model. The main contents of this paper are as follows: Firstly, by analyzing the related work of virtual ocean wave simulation, it is decided to choose the method based on geometric model to draw the surface of waves. Secondly, through the analysis of wave formation, it is affected by many kinds of environmental factors. We apply some of these factors to control the wave waveform, and through the study of various simulation methods, Fournier wave model is chosen as a relatively simple rendering method. Again, because the above model can not simulate the wave rolling, and in the simulation of breaking waves near the coast, the research starts very late and the technology is not very mature. Therefore, this paper uses the Fournier wave model to simulate the waves, and at the same time, it is reformed. So that it can produce waves and waves of simulation. Finally, according to the object-oriented design principle and the algorithm of this paper, the virtual wave demonstration system is implemented.
