geometry and topology meaning in Chinese
几何与拓扑
Examples
- An integrated information model of a product should include not only the information of the product ' s geometry and topology , but also its machining process information of manufacture oriented
一个完整的产品信息模型，不仅应具备产品的几何、拓扑信息，而且还应具备面向制造的加工和工艺信息。 - By this means , user can recover the model with arbitrary geometry and topology . during the interaction , the reconstructed results can be computed and displayed instantly because we use an optimization - tree based symbolic and numeric hybrid optimization - solving approach
采用这种方法，系统在接受使用者的交互之后，可以实时地求解几何参数与照相机投影矩阵，并即时地在一个三维窗口中显示重建结果，做到真正的所见即所得。 - The key techniques for reverse engineering based on ct image are introduced . 3d reconstructed surface model does n ' t possess full geometry and topology information as solid geometry model . this dissertation presents an algorithm for rebuilding solid model from triangulated patch surface mod
介绍了基于ct图象反求的主要技术；针对重建三维表面模型不具备象实体几何模型的数据那样的完备信息的特点，提出一种基于ct图象的反求技术的实体几何造型方法，将重建模型转换为边界表示的实体模型，并将其作为本研究所开发的特征造型系统3dmodeler中的一种反求工程实体造型手段。 - The design process of the proposed method is described as follows : the input of the method is the 3d sketch of a light steelwork , and the geometry and topology information of the members in a steelwork are established automatically . the steel types and function of the linked members are determined by means of interactive scheme according to the design requirements . and the arrangement of the steel members and their orientation are built according to the steel member ' s type , the function of the steel member , the knowledge of the steelwork and welding technology
在该方法中，首先通过交互手段输入轻型钢结构的三维线框简图、自动确定结构的几何和拓朴信息，根据设计要求输入各杆件的型钢类型和在结构中的功能；然后，根据型钢类型、杆件功能、钢结构设计知识以及焊接知识自动确定杆件的搭配关系、建立杆件的方位布置确定规则和节点板设计的规则；最后，利用这些规则来决定节点秆件连接关系、连接位置，确定节点板的类型、布置方位和位置，实现三维钢结构的结构自动设计。 - The design process of the proposed method is described as follows : the user inputs the 3d sketch of a welded machine , and the geometry and topology information of the members in the welded machine are established automatically . the design information is acquired by the means of man - computer interaction . according to the knowledge of design and welding , the rules of bar orientation , joint processing and welding sequence are established
用户在autocad中输入焊接机架的线框简图，提取出机架结构的几何和拓扑信息，然后通过人机交互输入设计信息，并根据机架的设计知识与焊接知识，建立机架的杆件方位布置规则、节点处理规则与焊接顺序自动确定规则，最后在autocad中生成经过节点处理的机架三维实体，并提供一套合理的焊接顺序。
