摘要
在分析分形理论和LOD技术的基础上,通过把中点位移算法和LOD技术完美地结合在一起,提出了一种生成地形的有效算法,该算法既做到了对地形总体轮廓的有效控制,又能够充分地利用分形特性表现地形表面的丰富细节,而且避免了大量数据的输入,使显示效果和资源的利用得到了最佳的匹配.
On the basis of analysis of the fractal theory and LOD technology algorithm for terrain generation is proposed by perfect combination of cantral-point displacement algorithm with LOD technology. This algorithm can effectively control the overall terrain contour and fully display the rich details of terrain surface with the aid of fractal characteristic, avoiding the massive data input, The algorithm achieves the best matching between resource usage and display effect.
