一种三维地形可视化细节简化方法

A level of detail algorithm for 3D terrain visualization

通过对数字高程模型数据多进制小波变换金字塔和基于二次误差的三维景观全局简化算法的讨论,提出了一种基于多进制小波变换改进的三维地形细节简化绘制方法,并给出了算法实验结果。

After analyzing the features of DEM multiband wavelets pyramid and 3D landscape drawing method based on quadric error measurement,an improved algorithm was proposed for simplifying 3D terrain drawing based on multiband wavelet transformation and some experimental results are provided.
