And seeking an the accurate mathematical model description of a variety of landscape of in the objective world,and realistic reproduce these phenomena and landscape, is an important research topic of the graphics. The topic from analoging the nature of the area with the Particles system of the graphic introductions the simulation of the real things. Many nature difficult to describe the geometric models, such as smoke, plants, water waves, flame, and so on, the features of particle system simulation model goes beyond the geometric constraints, can describes plex nature by a simple model.This topic designed the fountain model based on the OpenGL particle system, discussed detailly the properties of particles in the model and its changes, achieved a more realistic with the dynamic changes and changes in parabolic fountain features, used texture mapping and tracking technology for 3D vision Fountain rendering. the same time, Line way used to replace the traditional Point way exaggerated particles to achieve fountain simulation. The simulation way is a real fountain parison, speedly, in general PC can get satisfactory results.Key Words：Particle systems, fountain simulation, effects湖 南 大 學(xué) 畢 業(yè) 設(shè) 計(jì) (論 文 ) 第 III 頁(yè)湖南大學(xué)軟件學(xué)院目 錄1. 緒論 ........................................................................................................................................1 自然景物模擬概述 ......................................................................................................1 粒子系統(tǒng)的背景及其介紹 ..........................................................................................1 國(guó)內(nèi)外研究現(xiàn)狀 ..........................................................................................................2 噴泉模擬的要求及意義 ..............................................................................................32. 相關(guān)學(xué)術(shù)知識(shí) ........................................................................................................................5 物理學(xué)知識(shí) ..................................................................................................................5 數(shù)學(xué)知識(shí) ......................................................................................................................5 OPENGL .........................................................................................................................6 MFC...............................................................................................................................73. 粒子系統(tǒng)的設(shè)計(jì) ..................................................................................................................10 PARTICLE SYSTEM API.................................................................................................10 常見的粒子運(yùn)動(dòng)模型 ................................................................................................11 噴泉模擬的算法 ........................................................................................................12 噴泉粒子初始化 ..............................................................................................12 噴泉粒子的運(yùn)動(dòng)軌跡 ......................................................................................13 粒子的消亡 ......................................................................................................13 噴泉繪制 ..........................................................................................................14 紋理映射技術(shù) ............................................................................................................144. 系統(tǒng)實(shí)現(xiàn) ..............................................................................................................................16 開發(fā)環(huán)境 ....................................................................................................................16 粒子生成 ....................................................................................................................16 粒子活動(dòng) .............................................................
