For more information on the road, see the previous article: http://www.cnblogs.com/zhucde/archive/2009/03/06/1655247.html

Some time ago (Khan, a few months ago ).AlgorithmAfter doing this again, it is basically equivalent to abandoning the original practice. Now the speed is faster and the effect is better,

The textures in the distance and near areas are not the same:

 

The road start point is also integrated:
