【摘要】：隨著科學(xué)技術(shù)與計算機軟硬件的飛速發(fā)展,計算機圖形學(xué)在電影、游戲、廣告、軍事可視化仿真等方面得到了越來越廣泛的應(yīng)用。自然景物的模擬已經(jīng)成為計算機圖形學(xué)領(lǐng)域中最具挑戰(zhàn)性的研究方向之一。而在自然景物的模擬中,海浪的模擬卻是最為復(fù)雜的。 與植物地形等景物相比較,海浪具有著隨機性、動態(tài)性和不規(guī)則性,這些特性也給海浪的模擬增加了難度,也增加了對海浪模擬的挑戰(zhàn)性。本文通過對海浪建模技術(shù)的分析與研究,在考慮到海浪模擬的實時性與真實感的基礎(chǔ)上,決定以Fournier海浪模型為基礎(chǔ),通過對Fournier模型的改造,生成真實感和實時性較好的海浪模擬系統(tǒng),本文完成的主要內(nèi)容如下: 首先通過對前人的虛擬海浪模擬相關(guān)工作做出了分析、總結(jié),決定選用基于幾何模型的方法繪制海浪表面。 其次通過對海浪形成的分析,其受到多種環(huán)境因素的影響,我們運用到其中的一些因素來控制海浪的波形,通過對各種模擬方法的研究,選定了以Fournier海浪模型這種相對較為簡單的繪制方法。 再次因為上述的模型不能模擬卷浪,并且在近海岸碎浪的模擬方面,研究起步也很晚,技術(shù)不是很成熟,因此,本文在利用Fournier海浪模型對海浪模擬的同時,對其進(jìn)行改造,使之能產(chǎn)生卷浪和碎浪的模擬。 最后依據(jù)面向?qū)ο蟮脑O(shè)計原則,根據(jù)本文的算法對虛擬海浪演示系統(tǒng)進(jìn)行實現(xiàn)。
[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.
