摘要
根据地质体的层状特征和钻孔数据的特殊性,采用似三棱柱体作为基本体元构建三维实体模型。对三维实体的剖切能显示实体的内部细节。基于对话框模式的交互方式,采用旋转平面法矢量的方法确定任意剖切平面,并提出多边形拼接实体剖切截面的方法。该方法加快了三维实体剖切截面的显示速度,并在实际工程项目中得到了具体应用。
Build 3D geological model according to the layer-structured stratum and the particularity of the bore data. Sectioning threedimensional entity can show its interior details. Based on dialog box interactive mode provide freeform section planes by rotating vector. And a method to build section plane by polygonal splitting joint is put forward. The method speeds up the rendering of three-dimensional section. And the method is being applied to real project.
