【摘要】 虚拟漫游技术是一种跨学科的新技术,在建筑设计、室内建筑装潢、房地产开发、游戏设计等方面具有非常广阔的应用前景。本文在研究了虚拟漫游技术及相关理论的基础上,基于3DS MAX平台,融合面向对象编程技术,设计与实现了校园内场景的虚拟漫游系统,主要进行了下面几个方面的工作:(1)针对当前虚拟建筑漫游技术中使用的各种建模方法和建模工具,研究了利用3DS MAX软件建立建筑模型的方法。通过对各种建模方法的比较,结合工程实际,对原有的建模方法加以改进,提出适合校园建筑物建模的实用方法,即综合建模法。(2)对于漫游场景中的外部景观,如花草树木、天空等模型的建立,本着系统简单化的原则,采用简单几何体表示其外形,然后用纹理映射来保证景物的真实感的方法,实现了对其模型的建立,该模型克服了已有建模中多边形数量多,系统不堪重负的缺点,取得了真实感较强的场景制作效果。(3)将3DS MAX专用建模软件设计的比较复杂的室内外建筑模型,与VC++和OpenGL融合,设计了一个沿指定路线进行校园内场景漫游的系统。实现了对教学楼内、外场景的漫游。(4)为使漫游的画面流畅地运行,对系统进行了优化设计。一是对不可见部分进行隐藏或删除;二是在程序设计时,使用了顶点集、多边形列表及相关三角形列表,使用了缓冲区与深度缓冲区的双缓冲机制等方法,简化了系统的复杂度,使得本系统能够生成每秒15帧以上的漫游动画,取得了较好的漫游效果。实例证明,本文开发的校园内场景的虚拟漫游系统,保证了系统的显示速度,具有较好的真实感,满足用户对校园内场景虚拟游览的需要,漫游效果良好。更多还原

【Abstract】 Technology of walkthrough is a type of new interdiscipline technology.It is very promising in the fields of architecture design,interior decoration estate development and computer game design.Researched on the technology of virtual walkthrough and telated theory, based on 3DS MAX flatform fused with object oriented programming technology, this thesis designs and realizes visual walk-through system in scene of campus. This thesis mainly does the following items:(1) To research the method of creating building model using 3DS MAX software against with different modeling methods and tool used in technology of virtual walkthrough in architecture environment at the present time. By comparing with various modeling means and linked with the real project,improve the original modeling manner and present a practical method of modeling architecture in campus:synthetic method.(2) To use simple geometric object to express the outline,and then to use texture map to present real scene.To ensure the principle of simplified system,this mean is used in external scene of walkthrough system,such as plants and sky model.It is against the present method weakness of large quantity of polygon making heavy load on system,and can gain good reality scene effect.(3) To design a walkthrough system along required route in campus, fusing the complex interior and exterior architecture model with VC++ and OpenGL.It relizes walk through in interior and exterior scene of teaching building.(4) To design optimization system to make sure the trouble-free operation of walkthrough frame.One is hiding or delete the invisible part;another is using apex assemble、polygon list、related triangle table and double buffer.To simplified the complex system to generate walkthrough animation 15 frame per second.A case study shows that the developed visual walk-through in scene of campus has good reality,make sure the speed of system display,satisfies the require of customer on visual walk-through in scene of campus and gets fine walkthrough effect.更多还原
