title: Draw Line Connecting two Object/Vector3 Unity3d
body: <p>I am making game . </p>
  
  <p>In that i will have points(Stations) already given and on hitting those points, line should be started to draw till it reached to next point.</p>
  
  <p>as well as i want to avoid overlapping of lines.</p>
  
  <p>and line should continue to expand if i touch end of the line.</p>
  
  <p>I know 2 approaches to draw line 
      I can use linerenderer or else i can use GL class .</p>
  
  <p>I want to know which will be suitable for my requirement. and if you guys is having another idea then also you can share.</p>
  
  <p>I have seen vectrocity demo but its not free so i cant use.</p>
