Simplification of triangulation structure plays an important role in constructing three-dimensional models. The authors studied all currently-used triangulation-simplification algorithms and applied a very useful algorithm named TIN simplification based on Vertex Decimation to actual simplification of the three-dimensional terrain. Considering the huge quantities of data from the three-dimensional terrain, the authors made some improvement on this algorithm so as to render it more efficient. The simplified modeling using the improved algorithm simplification has the same error as the original algorithm.
