摘要
针对目前三维建模领域的现状及存在的一些问题 ,提出了基于离散算法的三维建模技术。从工程应用的角度出发 ,主要讨论了三维实体表面的数据预处理、离散化以及离散网络模型的拓扑关系和交互剖切算法 ,最后利用开放图形连接库OpenGL、ObjectARX、面向对象OOP技术开发了一套矿床三维模型仿真系统。该建模方法克服了传统算法建模数据结构过于复杂 ,交接拼合计算困难 ,难以建立数据之间正确的拓扑关系等局限 ,大大方便和简化了三维模型的建立过程。运行结果表明该三维建模方法操作简单、实用性强 。
In view of the current status of 3D modelling field and its existing problems, a discrete algorithm-based 3D modelling technology is put forward. Starting from the point of engineering application, the data pre-processing of 3D model surface, its discretization, the topological relation of discrete network model are highlighted.Finally, a simulation system of deposit 3D model is developed by technologies of Open Graphics Liabrary (OpenGL), Object ARX and Object-oriented OOP. This modelling method eliminates the limitations in conventional algorithm modelling, such as too complicated data structure, difficult combination operation and difficult establishment of a correct topological relation among data. The application results show that this 3D modelling method is both simple and practical, suggesting a good application prospect.
