Research On Visual Walk-Through Technology In Scene Of Campus

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.
