Figure 5-16. Moving an object in a loop using a cubic Bezier curve
Since the code for this example is essentially the same as in Example 5-12 (besides the
four points), we have highlighted in bold the changed code in Example 5-13 . We have
done this to show you that—with relatively simple changes—you can create dramatic
animation effects using cubic Bezier curves.
