Space Triangulated Irregular Network Intersection Algorithm

The subject explores the methods and processes to build triangulated irregular network models which adopts 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 sorts to result continuous polyline or closed cross wire loops. Through VBA language under the AutoCAD software achieves the initial grid model and eventually the cross line to generate Medium term data processing under VC + + compiler environment, in order to achieve efficient data processing to achieve the open pit construction and production process design digital simulation conveniently.
