画线代码：
最终效果图：
优点：
1.效果还行，计算量也不大（就一点2维直线一般式能有多少运算量）。
缺点：
1.每条线怎么也是建模，可能会有点开销。
2.编辑起来很是麻烦。

杂谈：
这个画线我还是花了点心血的~（T.T因为公司的项目核心就是这个鬼东西）。
最开始画线想的比较简单，直接用UISprite摆就好，结果摆出来的断面太明显了。而且一旦角度越刁钻断面就越明显。
后来采用建模的方式来创建线段，开头一切顺利，包括三角面创建，单面渲染等等，第一版本出来是这样的：
脚大马爹，这是什么鬼，为啥线又粗有细,经过我的仔细分析：
可以很明显的看书 1 和 2线长度完全不相同，当然横向的线比斜向的线粗很多咯，所以我后来引入了2维直线一般式，用直线2元一次方程求解的方式计算交点，完美的解决了线的问题，最后出来的效果就是效果图的效果了。
这里为了排线也是很花了点功夫，见下图：
不要问这是什么！我是不会说的。End！
