地矿工程三维可视化系统建模

建立相应的模型来表达数据的结构、规律,用来表示空间实体是地矿工程三维可视化系统的重要内容之一,而地矿工程的空间实体的三维表示则是公认的难题。针对矿山特性和应用,对体素模型和实体几何模型进行扩展并建立各种模型的适用情况,设计了地矿工程系统模型的混合策略,即以集成式混合策略为基础,根据不同的应用目的对两种模型分别采用互补式和转换式混合策略。最终通过模型的集成、转换实现了三维实体表达、现象模拟、空间分析和可视化。

Visualization System Modeling for Geological and Mining Engineering

It is one of the important contents of the 3D visualization system of geological and mining engineering to establish the correspondent model for expressing the data structure and law and show the spatial entity while the 3D representation of the spatial entity of geological and mining engineering is a widely recognized challenge.In light with the mine characteristics and application,voxel model and entity model were extended,the applicable conditions for the models were established and the mixed strategy of the model for geological and mining engineering was designed.That is,with the integrative mixed strategy as the basis,complementary and conversion mixed strategies are used for the two models according to different application aims.Finally,the representation of 3D entity,phenomena simulation and spatial analysis and visualization were realized through the integration and conversion of the models.
