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 -

Abstract : a new algorithm of area filling of geometry graph has been proposed. in this algonthm based on the area calculating theory of closed graph with curvilinear integral. the redundant judgement of inner pixels in the area has been eliminated and the defect of polygon area filling algorithm, which has some limitations to the graph shape, has also been overcome
文摘:基於曲線積分求封閉圖形區域面積的基本原理，提出了一種新的幾何圖形區域填充演算法.該演算法不需要對區域內點進行重復判斷，也克服了多邊形填充演算法對區域形狀有一定要求的缺點 -
In the algorithm, the convexity - concavity of vertexes and arcs must be identified, and a fast approach for identifying the convexity - concavity of line - arc closed curve is proposed. firstly, the orientation of a closed - curve is determined by constructing a new convex polygon. secondly, by using the orientation of the closed curve the convexity - concavity of vertices and arcs are identified
在演算法實現過程中，由於需要對圓弧和直線段組成的封閉曲線的頂點、圓弧的凸凹性進行判定，本文提出了一個圓弧和直線段組成的封閉曲線凸凹性快速判定方法，該方法首先通過構造一中介凸多邊形求出封閉曲線的方向，然後根據封閉曲線方向確定頂點及圓弧的凸凹性，進而確定封閉曲線的凸凹性。
