摘要
基于分形插值的基本原理,通过动态加入数据点的方式交互式建立地形模型,根据视点的参数对地形模型中数据点的合并或添加来调整模型的层次细节,有效简化了地形模型的绘制,提高了生成效率.最后利用OpenGL实现了三维地形的可视化处理,从而生成真实感地形.
A modeling method of the interactive terrain is established by adding into data-points based on fractal interpolation basic principle. We depend on factor of viewpoint for coalition and addition data-points of modeling to generation level of details model, the rendering of the terrain modeling is simplified effectively, and the efficiency of the terrain generation is improved. Visualization of 3-D terrain based OpenGL is accomplished, thus real sense terrain is generated.
