Interactive Raytracing Java Applet (polar coordinates)
Please allow a few moments for the applet to download and for Java to initialize... Once it's running, remember you can click the green question mark for a brief help listing. Don't see an applet coming up after a long time, or having difficulty with the applet freezing up? Double-check your browser security settings (allowing Java for this site), and try the Java applet tests suggested on the previous page. Lastly, so far as I know Java applets like this won't work on iOS platforms (but please let me know if you know an easy way to adapt this applet to do so!)
