摘要
基于面向对象的思想,在语义分离的基础上,从微观几何要素的角度对三维矢量模型的构建及其操作进行了分析,提出并实现了具有四层结构的三维矢量构模及其数据集成组织框架。基于该框架,能够以参数配置的形式快速形成一系列语义无关且具备强大操作行为能力的三维矢量模型组件(库)。在应用中,以模型组件+语义特性的方式进行地学建模,在更大程度上满足三维GIS以及VGE系统对各种地学对象及现象进行多样化表达模拟分析的需求。通过对某地区复合地质体的建模操作,验证了该集成框架及其所构建模型组件的正确性与有效性。
By adopting objected-oriented method, we begin with a profound analysis of the 3D vector models and possible operations from the micro perspective, and propose an integrated framework for 3D vector modeling together with its data organization. A series of 3D vector model components with powerful functions can rapidly be constructed in the form of parameter configuration with the help of this framework. By the way of model components ＋ semantic attributes, it supports the geo-science modeling in practice as well as the analogy and analysis of geo-science objects in VGE or 3D GIS systems. A case study was given to verify the validity and feasibility of the integrated framework together with its model components.
