| 摘 要： | 为了实现大量离散多波束水深测量数据快速网格化和地形三维可视化表达,提出了一种基于CGAL库的离散数据快速构建三角网,并利用OpenGL库实现了海底地形的三维可视化和自由漫游的方法,降低了编程实现的难度,海底地形细节显示清晰,并与Surfer软件的实现效果进行了对比.

| Abstract: | In order to realize rapid meshing of large number of discrete multibeam survey data and 3D visual representation of seafloor,this paper presents a triangular network based on the discrete data which could be quickly constructed by the CGAL library,and then 3D visualization and free roaming of seafloor is realized using the OpenGL library.This method reduces the difficulty of programming and the details of the seafloor topography could be clearly displayed.Comparison with Surfer software in terms of representations are conducted. |
