It's a simple program, that uses processing programming language to compute the Bezier curve on four control points. The control points could be selected clciking the screen. X- axis represents along the horizontal and Y-axis represent along the Vertical.
Press p or Esc to exit the program and any key to clear the screen.
There seems to be a small glitch so, it doesn't clear the screen completely, to completely wipe the screen press any key except p or Esc then, click mouse once and again press any key except the p or Esc. This totally clear the screen.
This was a simple work I did during my weeked so, doesn't conatian comments ans so but It does is fun to play with so I thought people might like it.
One Important thing, It might requires JAVA being installed on the PC to run the application. So make sure JAVA is installed, else it will direct to the page from where JAVA environment needed could be downloaded.
