Intersection Algorithm and Application of Spatial Irregular Triangular Network in Environmental Engineering

摘要

In environmental engineering, by constructing method of irregular triangular mesh model, a bounding method is used to box out the two triangular grid models in the large number of invalid triangle units, supplemented by spatial encoding technology to further position set intersection triangles, after multi-endpoint sequencing, continuous periodic lines or closed loops are obtained to form the envelope surface, which ultimately enable digital simulation in the process of production.
