This article discusses the Design and Implementation of the 3D model conversion program based on the object-oriented method , the actual projects , and on this basis, combined with 3D simulation training system model to generate the interactive part of the software . This paper introduces in detail the design and implementation process of the 3D model conversion process , based on detailed 3D simulation training system design and implementation, including requirements analysis, object-oriented analysis and design , process technology Difficulties and details . Fully integrated with the object-oriented technology in the design and implementation of the software , follow the software engineering methods for demand analysis , of the basic objects in the system , reasonable to class hierarchy design and realization . For 3D simulation training system and its model conversion process to achieve the technical details of the process , such as light processing , material handling , transparency , texture mapping , model strategies, fog treatment , BillBoard technology and applications specific issues , we have proposed the corresponding method , or algorithm , to meet the application requirements and improve system performance .
