摘 要: 探讨了基于地理特征的地形多分辨率模型生成过程中的模型简化评价指标,并且采用四叉树与二叉树结合的方法对模型三角化中形成的裂缝问题进行处理. The simplify criterions for construction of multi-resolution models was discussed based on geographic features. For the problem about carck brought out in model triangularization, a new technique combining quad-tree has been invented.
