地形模拟的一种分形几何方法——中心辐射法

Central Radiation——a Fractal Geometric Method for Topography Simulation

提出一种地形模拟的分形几何学方法———中心辐射法 ,直接从已知高程点出发 ,对周围区域进行插值 ,构造地形模型 .该方法较多地保留了地形的原貌 ,为真实地再现丰富的地貌特征提供了有效手段 ,也为工程设计计算创造了有利条件 .

The central radiation method, a fractal geometric method for topography simulation, is presented. Based on the given elevation data,interpolation is performed for the surrounding area,and the topography model is constructed.The method keeps many original features of topography,and provides an efficient means for the reappearance of the rich topography.It is also helpful for engineering design and calculation.
