摘要
根据公路三维模型的空间关系复杂,但位置固定,模型相对简单的特点,提出用八叉树这种数据结构来进行管理、存储的方法。针对普通八叉树存在着粘性平面的缺点,采用一种松散的八叉树的方法加以克服。
The spatial relationship of 3D model of Highway is complex, but its position is fixed and the model is simple comparatively. According to this specialty, a method that using octree to operate and store the models was presented. At the same time, a method called loosen octree to solve the stick plane problem of ordinary octree was also developped.
