【摘要】： 視景仿真是虛擬現(xiàn)實技術(shù)在實際應(yīng)用中的熱門研究課題之一，其中包括對火焰、云霧、雨雪、沙塵、浪花等動態(tài)自然景物和現(xiàn)象的模擬與繪制，在氣象預(yù)報、航空航天、裝演廣告等領(lǐng)域有著廣泛的應(yīng)用。自然景物具有豐富的表面紋理和不規(guī)則的表面外形，并且能夠隨時間的推移而動態(tài)地、隨機地發(fā)生變化，因此很難使用傳統(tǒng)的計算機圖形學的建模方法來生成。如何簡化而且有效地模擬這些不規(guī)則自然景物和現(xiàn)象成為計算機真實感圖形生成的關(guān)鍵問題。粒子系統(tǒng)能夠充分體現(xiàn)這類景物的動態(tài)性和隨機性，，其優(yōu)點在于使用簡單的粒子圖元來構(gòu)造出傳統(tǒng)計算機圖形學難以構(gòu)造的復(fù)雜物體，并且具有很強的真實感和實時性。 本文在認真分析和總結(jié)目前國內(nèi)外煙火模擬方法的基礎(chǔ)上，結(jié)合視景仿真對虛擬場景的需求和應(yīng)用，以友好交互性、較強的真實感和實時性為目標，提供了一種利用微粒來模擬煙火等自然現(xiàn)象的設(shè)計及實現(xiàn)方法。主要思路是先建立一個煙火的物理和數(shù)學模型，然后利用當前流行的軟件編輯器(如Visual C++)和圖形渲染庫(如DirectX、OpenGL)，將該模型轉(zhuǎn)化成計算機存儲和顯示格式，最終渲染成逼真的煙火等自然現(xiàn)象。還可采用合適的數(shù)據(jù)結(jié)構(gòu)、高效算法以及相關(guān)的硬件技術(shù)來進行一定程度的優(yōu)化，從而提高渲染效率。
[Abstract]:Visual simulation is one of the hot research topics in the application of virtual reality technology, including the simulation and drawing of dynamic natural scenery and phenomena, such as flame, cloud, rain, snow, sand and dust, spray, etc., in weather forecast, aerospace, etc. Dress advertising and other fields have a wide range of applications. Natural scenery has abundant surface texture and irregular surface shape, and can change dynamically and randomly with time, so it is difficult to use traditional modeling method of computer graphics to generate it. How to simplify and effectively simulate these irregular natural scenes and phenomena has become a key problem in computer realistic graphics generation. Particle system can fully reflect the dynamic and randomness of this kind of scene, its advantage lies in the use of simple particle graph elements to construct complex objects which are difficult to be constructed by traditional computer graphics, and have a strong sense of reality and real time. On the basis of analyzing and summarizing the methods of pyrotechnic simulation at home and abroad, combining the requirement and application of visual simulation to virtual scene, this paper aims at friendly interaction, strong sense of reality and real time. A design and implementation method of simulating natural phenomena such as pyrotechnics by using particles is provided. The main idea is to create a physical and mathematical model of fireworks, and then convert the model into a computer storage and display format using popular software editors such as Visual C) and graphical rendering libraries such as DirectX OpenGL. The final rendering into realistic fireworks and other natural phenomena. We can also use appropriate data structure, efficient algorithm and related hardware technology to optimize to a certain extent, so as to improve the rendering efficiency.
