Bezier

This app was originally published in 2009, and has been updated to run on modern iOS devices. --- Create and modify cubic Bézier curves. Up to 4 connected segments can be created and modified by moving the control points. Display the convex hull of the control points to see that a Bézier curve always stays inside it. Use the C1 continuity hint to make the segments C1 continuous where they connect. The resulting curves can be exported as a PNG image, and as an SVG file for further editing in programs like Inkscape and Illustrator. This is the iPhone version of a computer graphics Java applet I wrote back in 1996. Many enhancements are possible, suggestions are welcome at [email protected]
