| 1. | Reconstruction of wire - frame model from orthographic views
基于三视图的三维线框模型生成算法 |
| 2. | The main reason is a wire - frame usually cannot represent a unique 3d object
主要原因是线框模型表示的不唯一性。 |
| 3. | From the point of view of manufacturing it is necessary to convert the wire - frame to the representation of 3d objects automatically
所以工业制造商需要将线框模型的文本数据自动转换成三维实体模型。 |
| 4. | A wire - frame is possible to define several different 3d objects according to the vary observers and their observing direction
通常描述的线框模型就可以定义多个不同的三维实体，取决于不同的观察者和不同观察的角度。 |
| 5. | For example manufacturing companies often receive order with files of wire - frame representing design of progressive stripe without any geometric and topologic description
例如，工业制造商经常收到线框模型表示的三维实体文本数据，其中不附带任何的几何与拓扑描述信息。 |
| 6. | Used in combination with other work products such as wire frame models and design documents , uml can be a powerful way to communicate requirements and design to developers
与其它工作产品（比如线框模型（ wire frame model ）和设计文档）一起使用时， uml会成为一种向开发者传达需求和设计的强大方法。 |
| 7. | The main idea is to search for feasible panels made of vertex and edges according to the elemental principles of 3d object , and reconstruct 3d object from feasible panels
本文给出的基于线框模型重构三维实体求解算法，从三维实体的基本原则出发搜索由点、线组成的可行面，然后计算由可行面构成的三维实体。 |
| 8. | The software designed by myself can fulfill such importam woiks as creating and manipulating the product database which conform to ap216 , retrieving and storing data of a 3 - dimensional ship wire model
所开发的软件完成了符合船舶应用协议ap216的产品数据库的建立和操作，三维船舶线框模型数据的提取、存储。 |
| 9. | Although this phenomenon and assertion are well known , yet wire - frame as a graphics medium is still applied in some industry design and manufacture areas nowadays . it is because of that drawing a wire - frame is cheaper and easier rather than drawing a 3d object by solid modeling
虽然这一现象早已为人们所熟知，但由于线框模型形绘制比三维实体绘制快速、经济，因此线框模型仍作为图形表述的主要方法被广泛用于工业设计与制造领域。 |
| 10. | Achievements obtained are as follows : 1 . for the low efficiency of removing pseudo elements in the wire - frame , according to the broken lines in 2d views , the topological information and the relationship between the 2d information and the 3d information generated in construction , we give some definitions and propose some related theorems which have been proved correct
取得成果如下: 1 .针对重建的线框模型中假元判断条件的局限性和效率低的问题,根据二维视图虚线信息、拓扑信息及二维信息与重建的三维信息之间的关系,提出了一些新的定义,性质及定理,并给以了证明。 |
