According to the characters of three - dimension engineering, it designs data structure and data model by the method of oop. data structure of oop is applied to the modelling based on graphics. it realizes the display of three - dimension graphics in engineering. the system can import / export 3ds files. it realizes selection, feedback of 3d shape and the management of 3d shape ' s properties ; 3d shape frome 2d contour lines and the medial axis of a convex polygon and an arbitrary simple polygon are discussed
針對三維工程的特點,採用面向對象的思想進行數據結構與數據模型的設計;將面向對象數據結構應用於基於圖形的建模技術中,實現了工程中三維圖形的顯示,並通過與3ds文件的介面,導入造型復雜的模型進行補充;基於二維設備的三維交互問題,實現了對三維形體的選擇、反饋以及三維形體的屬性數據的管理;對由二維輪廓線構造三維形體,本文創造性的提出了利用多邊形的中軸來構造三維形體,並修正了求多邊形中軸的演算法。
