摘要
为了实现逆向重建三维模型导入到常规CAD系统后生成可参数化驱动模型,对逆向重建模型采用CSG/B-Rep混合模式表达,提出了一种基于XML描述的数据交换格式,可将CAD模型所需的参数信息包含在数据格式中,通过对CAD系统进行二次开发,导入XML文件,实现了以CSG/B-Rep混合模式表达的逆向重建三维模型与常规CAD系统的数据交换,扩充了逆向重建模型的重建意义。最后通过逆向重建模型与CATIA系统的数据交换实例验证了该方法。
In order to make the reverse reconstruction model be parameter-driven model after being imported into conventional CAD system,CSG/B-Rep hybrid mode is applied to represent the reverse reconstruction model,and a XML-based description of data exchange format is proposed,which contains all required parameter information of CAD model.After second development of CAD system,the XML files can be imported into CAD system,and accomplish the data exchange between reverse reconstruction models which are represented by CSG/B-Rep hybrid expression mode and conventional CAD system,which expands the reconstruction significance of reconstruction model.Finally,the method is verified by an example of data exchange between reverse reconstruction model and CATIA system.
