Abstract: 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.
