- Based on tmrm , critical technologies for real - time rendering of large scale terrain which includes tmrm generating technology , real - time rendering technology through streaming , terrain texture management and mapping technology are studied systematically in this thesis and some new results were obtained . there are many algorithms for generating tmrm models
多分辨率模型是目前地形实时显示的主要技术，本文以多分辨率模型为基础，对实现大规模地形实时绘制的关键技术，包括地形多分辨率模型生成技术、大规模地形的流式处理技术及地形的纹理组织和映射技术等进行了系统的探讨和研究。 - However , the data structure used by this method is very large for its dependence on the physical partition of terrain , computation needed for generating the tmrm is also depends on the physical partition of terrain and at the same time , the tmrm can not be generating incrementally by this method . to resolve these problems , we put forward a new method which can realize the real - time rendering of large scale terrain with high performance by working through streaming
采用逻辑调入粒度对数据进行流式处理，使得模型生成的计算量也比较稳定，不再依赖于地形的物理分割粒度；该方法采用的多分辨率模型还适合于并行处理模式，在具有多处理器的并行处理环境中，可将各数据块分配给不同的处理器，这也是lindstrom的处理方法不具有的特点。 - 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。 - Real - time rendering technology for large scale terrain is becoming a hot field which attracts more and more researchers " attention at present . it has been widely used in simulation of battlefield , vr , landscape programming of city , flood controlling , outdoor games , movie production , etc . the main method for terrain rendering is the terrain multiresolution model ( tmrm )
大规模地形的实时绘制技术是目前人们广泛关注和研究的热点课题，它的应用涉及到如战场环境仿真、城市景观规划、虚拟旅游、防洪减灾、户外游戏、影视制作、虚拟现实等众多应用领域。
