And finally the blending surface and smooth patch are investigated . this paper includes such contents as : according to the features of re , a software architecture which fits for re is designed , whose function is given separately . the surface reconstruction module is programmed by vc + + 通过以上工作，得出如下结论：在分析逆向工程系统软件所需完成的功能基础上，进行系统软件整体规划，并确定各模块所需完成功能，对曲面重构模块采用vc + + 6 . 0的鉴别器进行实现。
We can implement the intricate process about blending surfaces of three quadratic surfaces by modifying the parameters . we can display the intuitionistic images expediently by moving mouse on it . there are many works to do in the question about converting the intricate algrithom to the concrete application and developing an effective software . we must not only master the algorithm itself but also learn many developing tools , such as : maple , matlab , opengl , c + + and so on 本文基于对三个二次曲面光滑拼接的理论研究,应用maple对复杂数学公式进行了提炼,用opengl和vc + + 6 . 0开发出具有友好界面的软件,通过选择二次曲面类型和输入参数,可以将二次曲面拼接的复杂计算过程在计算机上进行具体实现和结果显示
