More Beziers

I now have quadratics, cubics, and quartics. Right now it's semi-hardcoded to the number of points in the curve. I'm trying to make a Bezier class that will create a Bezier out of any number of points, but implementing it is really confusing and difficult.

• Quadratic Creation:
  • Generate the 2 lines between the 3 points
    
  • Get the 2 points along the 2 lines at the particular interval
    
  • Get the line between the points
    
  • Get the point along that line at the particular interval, and draw

  [*]Cubic Creation:

  • Generate the 3 lines between the 4 points
    
  • Get the 3 points along the 3 lines at the particular interval
    
  • Get the 2 lines between the 3 points
    
  • Get the 2 points along the 2 lines at the particular interval
    
  • Get the line between the 2 points
    
  • Get the point along the line at the particular interval, and draw

See where it gets repetative?
