The structural framework of the on - line test system has been built in the paper, based on j2ee and xml. uml is integrated into the development of web application in virtue of rose to get visual system model. the system requirements and design models are defined by uml diagrams such as use case diagram, class diagram, sequence diagram, collaboration diagram, component diagram, and deployment diagram. web pages, component objects, data tables and databases are all regarded as a class or an object. the modeling process bases on the views of real world. the design and development process is established according to the views of software engineering. the online examination system which bases on j2ee can fully use the jsp 、 javabean 、 servlet 、 xml, flexibility of three - tier model to optimize the system performance and to enhance. the development value
同時藉助rose工具將uml語言和web應用開發結合起來，進行可視化建模，利用uml的用例圖、類圖、時序圖、合作圖、組件圖和部署圖等，定義系統需求，描述系統設計，將web頁面、組件對象、數據表和數據庫都作為類或對象，按照真實世界的觀點進行建模，依據軟體工程學的觀點制定設計開發步驟。本系統以j2ee體系結構為基礎，充分利用jsp 、 javabean 、 servlet 、 xml組件和三層模式的靈活性來簡化開發過程，優化系統性能，從而提高了系統的開發價值。 -
All algorithms that introduced hi my paper focus on the hollow hull of object, and the calculations are a series of intersection of face and line that have no ply. and by employing the topology information that come with the points since their generation, we can get the surface polygonal mesh without triangulation and reduce the time used in reconstruction of visual hulls and help to realize real - time rendering
本文提出可見殼的生成演算法都是建立在無厚度的平面直線求交計算上，完全避免了對物體內部的冗餘區域的計算，同時利用物體表面點集與生俱來拓撲信息，恢復物體表面的多邊形網格，在一定精度范圍內可以避免對散亂點集進行三角剖分，減少可見殼的生成時間並有助於實時繪制的實現。 -
This visual carnival greatly stimulates the audience ' s desire, and people ' s requirement of visual expectation and delight has been continuously improved. visual culture has already transformed the man - made visual symbols into our basic range of recognition, while natural object and real object withdraw to the second line
這種視覺的狂歡空前地激發著觀眾的慾望，人們的視覺期待和對視覺快感的要求不斷的提高和攀升，視覺文化已經把人造的視覺符號轉化為我們基本的認知領域，自然物和現實物倒退居次席。 -
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。 -
