However , the second technology has the following disadvantages : first , data paging and tmrm generating are integrated into one modulate , next , data structures they used are very complicated and large , in addition , the work of data preprocessing is very heavy and frequently data paging need the server with high performance , at last this paging method is very difficult for implementation . as for the first technology , an important advantage of it is that the data paging and tmrm generating are not interdependent , so it will be more e asily applied in practice than the second one . as an implementation of the first technology , lindstrom introduced a method which uses quadtree and triangle binary tree to organize terrain data and adopt multithread mechanism to realize the data process
而第一种流式处理技术尽管一次调入的数据量稍大，但其数据调度与多分辨率模型的生成在功能上是相互独立的，如果处理得当更容易在实际工程中得到成功的应用，对于它的实现， lindstrom提出了利用四叉树及三角形二叉树进行地形数据组织并利用多线程机制进行数据调度与简化的流式处理方法，但该方法的缺点是：其数据结构依赖于地形的物理分割，因此数据结构庞大；多分辨率模型生成的计算量也依赖于物理分割的粒度，即物理分割粒度较粗时，数据范围增大，计算量会急剧增加；该方法不能实现模型的增量生成。
