摘要
基于不规则四面体的三维实体建模方法具有很多优点,但在层状矿体的建模中,该方法却不能准确地描述其层状界面。根据层状矿体建模数据的特点,先将层状矿体的等高线进行等距离散化,再建立不规则四面体三维实体模型,并为该方法设计由点、面和四面体组成的逻辑模型结构。该方法用VC++.net编程得以实现,并使用内蒙某煤矿的实际数据,建立了相应的矿床三维实体模型。实践表明,通过离散化等高线后建立的层状矿体四面体模型,能够准确反映出层状矿体的层状界面,实现对层状矿体的三维实体建模。
The method of 3D solid modeling of irregular tetrahedron has many advantages,but the method can not accurately describe the layered interface in the layered ore modeling.According to the characteristics of the layered ore,the 3D sol id modeling of irregular tetrahedral was established based on equidistance discrete contour.The logical model structure of this method formed point,face and tetrahedron.The method has been realized by programming with VC＋＋.net.A 3D solid model of irregular tetrahedron has been established by actual data of a coal mine.Practice shows that the method can establish 3D solid model and accurately describe the ore body of the layered interface.
