title: How to draw wireframe sphere in opengl es
body: <p>Can you please submit a code for drawing a basic wireframe sphere without texturing it. I found plenty of examples but they use 3 kind of buffers like normal,texture and vertices. Is there any simple comprehensive way to draw a sphere using GL_TRIANGLE_FAN or GL_TRIANGLE_STRIP and using only vertex and fragment shader.</p>
  
  <p>Thank you!</p>
