Java no longer works in many browsers. You may want to use the new, non-Java browswer version.

Cycloid Applet is a program to generate graphcs of Curtate Cycloids, which are the curves produced by a point within a wheel, when that wheel is rotated. The intended users of cycloid applet are makers of stringed instruments, but the program is available for anyone to use. Cycloid Applet creates the graphs in PDF, PostScript, or DXF format.

The cycloid generating program was ported to Java by Sukwon Oh.

Note: PostScript and PDF expect a decimal point (.) and not a comma (,); ie, your numbers should look like 123.3 and not 123,3. Java will use whatever matched your local conventions, and the resulting PDF/PostScript will be invalid if it uses a comma. You may need to install the appropriate English language package to get things to work properly.
