| Abstract: | Spline surface patches based on 4 side region and triangular net are often adopted to express the shape of ground. Combining the merit of these two methods, a new method based on 3 side B B surfaces is introduced to describe complex digital ground model. Triangulation algorithm and redundant data reduction algorithm are presented to generate optimum triangular net, which are proved laconic and effective in large scale data examples. The STL file generated in the algorithm can be used in fast manufacturing the real model of the ground. |
