摘要
三维实体模型是建立三维可视化信息系统的基础,通过对几何造型及图形处理基本理论和方法的研究,基于构造实体几何法的理论,对ObjectARX工具中三维图形接口和实体造型方法进行了探讨,用Visual C++和ObjectARX工具进行二次开发,实现了三维实体自动建模、图形变换和布尔运算等操作方法 ,并以桥梁结构为例进行了的参数化建模,为桥梁信息化平台的建设提供素材。
Three-dimensional entity model is foundation for the building of 3D visualization information system. Through the research on the basic theory and method about geometric modeling and graphic processing, the paper discusses three-dimeusional graphics interface and solid modeling method in ObjectARX tool which are based on the theory of constructive solid geometry. It realizes the three-dimensional solid automatic modeling, graphics transformations and Boolean operations with Visual C＋＋ and ObjeetARX tool for secondary development. Bridge structure is taken as an example of parametric modeling. It is the basis of the construction of bridge Information platform.
