摘要
研究和分析基于分形理论的三维立体地形建模算法的数学原理,实现步骤,优点和存在的不足。重点讨论四边形细分法的基本原理以及在三维地形建模中的应用,并通过OpenGL语言对其进行可视化仿真。实验结果表明,算法有效、可行,完全可应用于大型地理信息系统和可视化系统中。
Researches and analyses the 3D terrain generation algorithm principle and process based on fractal theory.Mainly discusses the basic principle and the application of Diamond-Square method in 3D terrain generation.And simulates the Diamond-Square method using OpenGL program.The simulation results show that the algorithm is effective and feasible,and can be completely applied in the large scale geographic information system and visualization system.
