title: How to calculate control points in cubic beizer curve
body: <p>While going through a cubic beizer curve program<br>
  I found it uses end points as(10,10,0) and (0,1,0) and other control points as(5,10,2) and (-10,-5,-2).I am not able to understand how did they get this other control points<br>
  please help me with any formula or method to fins them<br>
  Edit:-<br>
  if you want to put a Bézier curve smoothly through N points with N>2, how do you get the intermediate control points.</p>
