If your browser is not Java-enabled, this page will look very boring. This applet was compiled with the beta 1.0 release of Java, so will not be viewable with HotJava.
Instructions Use the radio buttons at the bottom of the applet to select the curve-point mode.
In add mode, clicking on the display will add a curve control point. In delete mode, when you click on a control point, it will be removed. In move mode, you can click and drag control points. Select the curve type from the radio buttons on the top of the applet. The clear button will remove all the control points.
