| 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。

| Abstract: | 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. |

| Keywords: | 3D model of highway octree stick plane loosen-octree |
