华南理工大学硕士论文Abstract 华南理工大学硕士论文 Abstract In the field of 3DGIS，sound-images is new technology．Its simulation of sound effect can lead sound and images’knowledge．Specially，in the inner development of special effect，there many characters． This research is based Vega，it’s purpose is to let the inner sound attenuation，absorb，reflect come true．It analyzed the arithmetic of sound attenuation，reflect，metope absorb，cruise and so on．It also analyzed the used means and theories．It particular introduced the material realizing ways of VR，and analyzed its feasibility．At one time，this paper talked about some details．It includes OO software，design mode，and windows’core thinking and so on．It tries to find some material thoughts and general means．This paper also introduced how to re—design Vega under VC+÷and MFC． Some core technologies are here， (1) Founded model of sound line．Solved some problems in the transfer of sound； (2) Used triangles to plot out the interface．Used measure in the development； (3) Founded model of sound absorption in Vega； (4) Solved the audition simulation’s problem in Vega． After a plenty of study of Vega，some APIs，correlation arithmetic，this paper practiced its theory．With the help of modeling software and actual VR’s need，it carried special effect’s exploitation．This system based on opera，and shows us an effect of sound-images．It makes inner sound VR to be possible． This paper focused on the associative of sound and images．Beside of this，it studied the means of cruise in MFC．The way it used is filied to common VR design．At last，the paper is re—design of Vega，which is field of 3DGIS，so we can say it developed the application of computer graphics application． Keywords：Computer application，Virtual Reality,VR，Sound-images，sound pressure，reflect，sound absorption Ⅱ 华南理工大学 华南理工大学 学位论文原创性声明 本人郑重声明：所呈交的论文是本人在导师的指导下独立进行 研究所取得的研究成果。除了文中特别加以标注引用的内容外，本 论文不包含任何其他个人或集体已经发表或撰写的成果作品。对本 文的研究做出重要贡献的个人和集体，均已在文中以明确方式标明。 本人完全意识到本声明的法律后果由本人承担。 作者签名：巧玄 日期：2005年f月扣日 学位论文版权使用授权书
