"数字地形模型的Delaunay三角剖分算法实现与应用"

The Delaunay triangulation algorithm is a key component in the generation of digital elevation models (DEMs) for representing and storing irregular terrain data. This algorithm is particularly important for creating a three-dimensional representation of terrain that is both efficient and accurate. In comparison to other methods, the Delaunay triangulation algorithm has proven to be the most effective for terrain fitting, making it a popular choice for TIN generation. By following the Delaunay triangulation principles, the algorithm advances directly from the edges, rather than inward from the convex hull, resulting in a significant increase in speed and efficiency. This improvement has been demonstrated through simulation experiments, showing a marked increase in algorithm efficiency. Digital terrain modeling is essential for various applications such as urban planning, environmental management, and engineering design. A precise and realistic depiction of terrain is crucial for making informed decisions in these fields. The Delaunay triangulation algorithm plays a critical role in achieving this goal, as it provides an effective means of creating TIN models that accurately represent the complex topography of the land. In conclusion, the implementation and application of the Delaunay triangulation algorithm is vital for the generation of digital elevation models and the accurate representation of terrain data. Its efficiency and effectiveness make it a valuable tool for various fields that rely on accurate terrain modeling. Further research and improvements in this algorithm will continue to advance the capabilities of digital terrain modeling, allowing for a more detailed and realistic representation of the Earth's surface.
