And the nested error metric can eliminates the cracks in the meshes of the terrain surface automatically and implicitly 本文定义的嵌套误差判据球可隐式地保证地表网格中裂缝的自动消除。
In this dissertation , the definition of an appropriate and valid nested error metric sphere is presented , and a fast continuous lod terrain rendering algorithm is proposed 本文在定义了一种合理且有效的嵌套误差判据球的基础上,提出了一种快速的、视点相关的、连续层次细节地形表面绘制算法。
In addition , the error comes from the arithmetic discussed above is analyzed and an error criterion which made this arithmetic suitable for forecasting the loading noise in engineering is given based on the calculational results 并结合实际算例,对本文算法中所产生的误差作了比较分析,总结出了一个误差判据。
