Bezier Curve Drawing

-----------------------------------

a few days ago, i started looking into what bezier curves were and decided to try to create an algorithm to draw one. just this morning, i had an idea for UNLIMITED points and immediately implemented it into a function giving me this basic program...

- draws each node as a medium-sized black circle
- draws a green line between each node so you can tell which order the nodes are
- draws the bezier curve in blue
the program draws 1000 line segments fitting the curve, so feel free to play around with that number if it lags

  CONTROLS  
left click + drag . . . move a node
left click the "new" button . . . add a new node in the center of the screen
right click . . . delete a node

hope you enjoy, please leave some feedback

EDIT: i feel as though i should cite where i got my information of Bezier curves so others can look there because my code isn't documented very well...

Good job! I made this one a year ago for fun using bezier curves:

Can someone explain the basics of Bezier curves/link a tutorial for me?

I can't find the info anywhere!

Grapefruit: Check out the links i sourced in the first post, thats pretty much all i read
Raknarg: i think i remember you posting that, i had no idea what it was doing so i kinda forgot about it... Ill take a look at it tomorrow when i can get on a computer :)

Even better, evildaddy, is bezier curves in 3d ;)

Raknarg: I kinda want to try 3D curves sometime, that would be pretty cool, especially if i have the nodes bouncing off the sides of a cube? I think Ill get on that...
