First, the system builds the model of the bank and bottom of river, according to the river ’ s information and the information of the scene on the two side of the river. second, i read and preprocess the model file data and implement the organization and encapsulation about the space data of the virtual river. in the end, adopting to use these rending technology, such as show list, priority texture, and level of detail, i realize the real - time and vivid showing of the three dimension river ’ s virtual scene and provide abundant ways of people ’ s interacting with the virtual scene, on base of sufficiently making use of the memory of vision card and the cpu of the computer
它主要融合虛擬現實技術、三維數據可視化技術、面向對象的設計和編程技術，在vc + +平臺上，利用opengl三維圖形開發庫，以真實的城市河道現狀信息和周邊景物信息為依據，對河道、河底的三維空間數據進行三維幾何建模;然後通過讀取和預處理模型文件數據，實現虛擬場景空間數據的組織和封裝操作，並對空間數據進行優化;最後採用顯示列表、紋理優先級、細節層級模型（ lod ）等渲染技術，利用opengl的渲染特性，在充分發揮顯卡內存、處理器等各種軟硬體資源的基礎上，實現三維河流實時逼真的真實感虛擬場景顯示，並提供豐富的人機交互手段。 -
Here, the managed objects are classified into four types : m - based ( storing all resource information in memory ), md - based ( storing the base managed object in memory and the list of attribute in persistent storage ), mr - based ( storing the base managed object in memory and accessing the resource directly ) and d - based ( storing all resource information in a database ). to achieve those, a generic class is designed for the need of the basic managed object ; as a result, the managed object class abstracted from the managed objects mentioned above can be derived from this generic class when corresponding attributes and methods are added. finally, a mib storage structure of a real application inherited from its super classes can be constructed
該實現方法首先根據管理系統中被管對象的特點將其分為基於內存（ m - based ） ，基於內存?數據庫（ md - based ） ，基於內存?指針（ mr - based ）和基於數據庫（ d - based ）等四種類型；其次，定義被管對象基類用於描述通用的被管對象，然後以此基類為基礎，繼承並添加與具體模式有關的數據成員和方法成員，實現其它類型的被管對象類；對于具體的網管應用，則根據具體要實現的被管對象特點，從合適的被管對象類衍生，添加與具體應用有關的代碼，即可實現相應的mib存儲結構。
