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.
-
If the canvas has control points drawn on it, then pressing
Enter
should start the animation. It should cycle through the steps until reaching the 7th step ofChaikin's
algorithm. The animation should then restart. -
If the user presses
Enter
before any points have been drawn, then nothing should happen. It should still be possible to draw points. You may optionally choose to display a message to inform the user that they forgot to draw points. -
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.
