Chaikin

Instructions

Implement Chaikin's algorithm as a step by step animation.

You will create a canvas to enable the user to draw 1 or more points. The screen will then animate each step that is taken to obtain the final result of a drawn curve. The animation must play for 7 steps and then it must restart.

You can see how the application should work here.

Usage of Chaikin's algorithm is mandatory.

Functionality

  • The canvas must receive input from the mouse. The user must be able to use the left button to place control points for Chaikin's algorithm.

  • The selected points must be visible on the canvas. You will need to draw a small circle surrounding each point.

  • After pressing Enter, the program should start the animation. It should cycle through the steps until reaching the 7th step of Chaikin's algorithm. The program should then restart.

  • If the canvas only has only one control point, the program must only present that point and not cycle through the steps.

  • If the canvas has only two control points, the program must draw a straight line.

  • Pressing Escape should quit the window.

You are free to use any library to create and handle windows, rendering, keyboard and mouse events.

Bonus

  • Make it possible to clear the screen, so that the user can select new control points.
  • Make it possible to drag the control points in real time.
