四元树
Examples
- A view - dependent multi - resolution terrain simplification based on adaptive quadtrees
基于自适应四叉树视相关的多分辨率地形简化 - 24 frisken s f , perry r n . simple and efficient traversal methods for quadtrees and octrees . j . graphics tools , 2002 , 7 : 1 - 11 . 25 zhang h , hoff k . fast backface culling using normal masks
实验表明，新方法能将顺序点模型树的绘制效率提高20 % 64 . 6 % ，并且越近观察模型或模型中的遮挡关系越复杂时，新方法的加速比更高。 - In this disseytation , we present a new algorithm of view - dependent multiresolution terrain simplification based on adaptive quadtrees . especially , we discuss these main problems in multiresolotion terrain rendering such as levels of detail mesh generation , vedex evaluating and er
最后，将该算法应用于dem地形模型简化中，简化前的地形绘制帧速率为4fps ，简化后的地形绘制帧速率为70fps左右，在绘制图象质量没有明显退化的前提下，能满足视觉和实时划览的需要。
