场景漫游路径的优化设计是三维场景流畅性的关键。首先，根据OpenGL相机控制原理，定义了路径数据格式，包括路径点坐标等基本属性。然后基于三维模型的特点，提出了用路径点交互拾取、手动漫游和地下巷道中心线转换方法获取路径，并通过路径拼接、路径拟合和碰撞检测方法对获取的路径进行优化。最后实现了手动和自动2种方式控制漫游。实验结果表明，这种方法简化了路径的创建步骤，达到了理想的漫游效果。

The optimization design of scene roaming route is the key to get fluency of 3D scenes. First,according to the OpenGL camera control principle,the path data formats are defined,including the waypoint coordinates and other basic attrib-utes. Then,based on 3D model of coal mine,some wags that waypoint interactive pickup,manual roaming and roadway center-line conversion method are proposed to get route,and optimize the route through the path splicing,path fitting and collision de-tection method. Finally,roaming control is realized in manual and automatic ways. The experimental results show that this meth-od simplifies the path creation steps and achieves good roaming results.
