Bezier

A simple app to create and modify cubic Bézier curves.

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 bezierapp@gmail.com
