title: How to draw a sphere in OpenGL ES 2 correctly
body: <p>I was wondering what the difference between <code>gldrawarrays</code> and <code>gldrawelements</code> is?  Also which would you use and when?  Another question i have is how to draw a sphere for the android.  Say i have 360 points on the perimeter for a circle, does that mean i will need 360 * 360 coordinates for a sphere?  That seems to be very expensive, there has to be a better way.  The only way i can think of so far is doing nested for loops.  But that's going to be so much processor time.  Another way i can think of is drawing it and rotating it 360 degrees in a direction.  But then it's not really a true sphere, just a rotated circle.</p>
