title: How to draw "glowing" line in OpenGL ES
body: <p><img src="https://i.stack.imgur.com/1VYg4.png" alt="enter image description here"></p>
  
  <p>Could you please share some code (any language) on how draw textured line (that would be smooth or have a glowing like effect, blue line, four points) consisting of many points like on attached image using OpenGL ES 1.0. </p>
  
  <p>What I was trying was texturing a GL_LINE_STRIP with texture 16x16 or 1x16 pixels, but without any success.</p>
