松下手機的逆向造型研究
 摘  要：隨著計算機技術(shù)的迅速發(fā)展，計算機三維造型技術(shù)特別是逆向工程技術(shù)在工業(yè)上已經(jīng)得到了廣泛的應(yīng)用。為了解決手機外形設(shè)計周期長的困難，本文研究了手機外形的逆向工程造型方法，并對逆向工程概念、方法進行系統(tǒng)的闡述，同時又以松下G60手機為例詳細介紹了對手機外形進行逆向工程的步驟。

 Abstract: With the rapid development of computer technique, the technology of 3D computer-aided prototyping, especially the Reverse Engineering, has been more widely used in industry.  In order to solve the problem of long time on the mobile phone’s shape-design, a method based on the integrated reverse engineering is discussed in the paper.  Furthermore, the concept and method of the Reverse Engineering is also illustrated, and the step of the integrated reverse engineering of mobile phone’s shape-design process is presented in detail with the example of Panasonic G60.
