By constructing the list of vertices of polygon and intersecting points between polygon and rectangle, the list of vertices of rectangle and between polygon and rectangle, the list of incoming points and the list of outcoming points, the problem that how to confirm close clipped area edge is solved. at the same time, the second encoding technology is developed from line clipping to polygon clipping so that the speed of algorithm is increased
矩形窗口多邊形裁剪的改進演算法通過引入多交表、矩交表、入點表、出點表等線性鏈表，解決了如何確定一般多邊形在矩形窗口裁剪后封閉區域邊界問題，並把二次編碼技術由線裁剪拓展到多邊形裁剪中，對處于窗外的多邊形的邊可直接處理，提高了演算法的效率。 -
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 -
In this paper, i will present some algorithms of polyhedral visual hull reconstruction : ( 1 ) polyhedral v isual h ull generation a igorithm b ased one dge - pool - searching, which constrains the 3 - d intersections into the 2 - d planes intersection via the epipolar theory to reduce the complexity a nd c an r educe t he t imes f or c ones t o b e p rejected o nto t he i mage p lanes, i n which we induced the index list to every points on the surface of object, and connected the related points to get sub polygons on surface and in turn get the mesh model, we replace triangulation process of disordered points cloud by edge - pool searching. ; ( 2 ) reconstruction based on degenerated - polygon - intersection, which have the following improvements on traditional bull intersection : using degenerated polygon to orga nize intersected area on cone face, which may be discontinuous ; a fast intersection algorithm of polygons on the cone face based on degenerated polygons, which is consistent between the continuous polygons and the discontinuous ones. the intersection of degenerated polygons is similar to the convergence of two ordered lists, which is comparably simple to the bull operation ; ( 3 ) reconstruction algorithm based on ray - tracing, in which all the rays that run through the vertex on silhouette of object will intersect with all the cones correspondent to other silhouette, and we have to calculate the intersection of all such line segments, the endpoints of which are considered to lie on the surface of object and we will get the point cloud on the surface of object
同時利用共極線原理把三維計算投影到二維平面以降低求交計算的復雜度，該演算法可以減少光錐向圖像平面投影計算的次數，以邊池搜索取代散亂點集上進行的三角剖分； （ 2 ）基於退化多邊形求交的多面體可見殼模型重構，系統引入退化多邊形的概念，把錐體平面的交集中不連通的部分用一個退化多邊形來表示，並引入了新的基於退化多邊形的求交演算法，與傳統多面體可見殼重構相比，該演算法有以下幾點創新：在圖像平面以退化多邊形組織投影錐體和物體輪廓的交集，把任意錐面與物體輪廓的交集歸一到一個退化多邊形；基於退化多邊形的二維平面上多邊形快速相交演算法，該演算法在一定程度上就是兩個有序鏈表的合併，大大簡化了先前的布爾求交計算； （ 3 ）基於光線跟蹤的演算法，該演算法中所有通過輪廓頂點的光線和對應其它圖像輪廓的光錐進行求交計算，最後得到每次求交計算得到線段的交集，該線段的頂點就認為是物體表面點，從而得到物體表面的點雲。 -
