Abstract : a new data structure that one link - list was composed of polygon - surface table, edge table and vertex table was proposed to describe the geometry information and topology information of control polyhedron m in the rese arch of modeling with closed surface. compared with other structures which were a pplicable to the work, the structure was understandable, economize and conveniently to modify. after describing the detail of the geometry information, topology inf ormation included in the tables of polygon - surface, edge and vertex, and the poin t - link form of the adjacency multilist between the tables, a concise instance was given in clanguage array
文摘:介紹了在閉曲面造型研究中，為描述控制多面體m的幾何信息和拓撲信息而設計使用的一種單鏈三表的數據結構.與其他適用與描述控制多面體的數據結構相比，該結構在結合了鄰接多重表方法后的特點是:關系描述清楚，節省存儲空間，方便查找和交互修改形體.在介紹單鏈中三表（面表、邊表、頂點表）所含的幾何信息細節、以及單鏈的三表之間的表示面、邊、頂點拓撲關系的指針的鄰接多重連接方式之後，本文給出了以c語言數組方式簡明描述的數據結構實例 -
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。 -
This article proposes in order to quickly hidden processing is carried on to multi concavo - convex polyhedron, the hierarchical structure is applied to carried on description on topo relations of three dimensional physique ; the bidirectional link table is applied to carried on the dynamic node assignment, for enhancing the efficiency of the algorithm ; when multi three - dimensional body is being hidden processing, the screen projection polygon should be carried on the overlaped eliminating confirmation and the polygon edges be carried on the computation of the intersectant points, the depth inspection, the comprehensive test and so on
摘要文章提出一種對多個凹凸形多面體進行消隱處理演算法，並介紹了採用層次結構進行三維形體的拓撲關系描述；採用雙向鏈表進行動態結點分配的演算法，提高了演算法效率；對多個三維物體消隱處理時，進行屏幕投影多邊形的重疊排除驗證，對多邊形邊進行交點計算，深度檢查，包容性測試等。 -
Firstly, singly linked lists are used as the data structure of this algorithm rather than doubly linked lists or trees as other algorithms use, so less memory space and running time are required. secondly, the relationship between the entry and exit points on the two polygons is found and argumentation, which, with the reasonable operations on the lists, reduces the times that the lists are traversed and allows the polygon to be input clockwise or counterclockwise
該演算法使用單線性鏈表數據結構，與其它使用雙鏈表或樹結構的演算法相比具有佔用空間少及處理速度快的特點；其次，找出並論證兩個多邊形之間進、出點之間的關系，並通過合理的數據結構處理，減少了演算法對多邊形鏈表的遍歷次數，而且允許多邊形既可以按順時針方向也可以按逆時針方向輸入。 -
