摘要
通过构建不规则三角网模型的方法,采取包围盒方法排除两三角网模型中大量无效三角形单元,辅以空间编码技术进一步定位相交三角形集合,即利用AUTOCAD软件下的VBA语言实现初期网格模型构建和最终交线生成;中期数据处理采用VC++编译环境,对其进行相交检测并求出交线端点坐标,经过端点排序最终生成连续的多段线或闭合交线环形成包络面,此举能够极大地降低计算过程的实体建模和运算的大量数据而导致的计算效率低,最终准为实现露天矿生产过程中数字化模拟。
The methods and processes were explored to build triangulated irregular network models which adopt the bounding box approach to exclude the large number of invalid triangular elements in the two triangular network models,supplements by space coding technology is further positioned to intersect the triangle collection.The endpoint was sorted to result continuous polyline or closed cross-wire loops.Through VBA language under the autoCAD software,the initial grid model and the cross-line were eventually achieved to generate medium-term data processing under VC ＋ ＋ compiler environment.In order to achieve efficient data processing,the open pit construction and production process design digital simulation were achieved conveniently.
