IDE has a distracting flicker when the points are moved, and needs to be refreshed when the applet moves offscreen or is covered up. So which applet is better? There is a smoothness to the JavaSketchpad applet that the IDE applet lacks. Visual Cafe has been developed and distributed by Symantec and then by WebGain, but its current status is unclear. The Java applet was developed in the Integrated Development Environment Visual Cafe 4.5 ( zipped Visual Cafe project files). (Here is the gsp file to generate the sketch.) The following applet shows the same idea implemented from scratch: This applet was generated in Sketchpad by saving the sketch as an HTML file. Sorry, this page requires a Java-compatible web browser.
For example, here is the JavaSketchpad version of an activity to manipulate the vertices of a right triangle, with the goal of calculating values of trig functions directly: I started using JavaSketchpad to write online laboratories for a trigonometry course with the idea of writing Java applets of comparable functionality from scratch myself, but for the most part I have stuck with the original JavaSketchpad prototypes.

The story goes that when tools such as Visual Basic and Delphi became available, software developers would use them to develop prototypes for products they were considering, and then when crunch time came at the end of the project timeline they would just ship the prototype.
