摘要
从模型的数据结构、地质模型的构建、模型实现的行为等三个方面阐述了面向对象的层状矿床的三维地质模型的构造方法。模型数据结构设计简单,可以通过三角形查询此面上的点的厚度、倾角、走向和高程等属性,通过三角网的顶点可以查询顶点座标和法向量等属性;模型的构建采用插入法使得模型在编辑修改时变得简单。以多边形界内体积计算、三角网模型切割的折线描述以及等值线绘制等为例,介绍了构造模型的应用情况。
From 3 aspects of model data structure,geological modeling and model implementation expounded object-oriented bedded ore deposit 3D geological modeling.The design of model data structure is simple,can inquire about attributes of thickness,dip angle,strike and elevation on a given triangle,through vertex of a triangular mesh can inquire about attributes of vertex coordinate and normal vector.To use interpolation in the modeling makes the model compiling and amending simple.To take the volume computing within a polygon,triangular mesh model incision polygonal line description and isoline plotting as examples,introduced the application actuality of the model.
