Web input/output
Dec 24th, 2008, 8:00am  
I have been working on a fractal generator in processing (see http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Exhibition;action=display;num=1228449676 )

I don't really intend to do this (time is limited), but I might if it's not too hard.

Suppose I were to make a community driven genetic fractal parameter tuner. Basically you go to the web page, and get a processing app that downloads a small text file detailing the current generation. It then generates some fractals which you choose from, and the results are returned to the server.

There are two things here I don't know how to do:
1) download the text file from a fixed address into the web app (it can be in a friendly directory next to the app on the server if desired).
2) return some data to the server. I could pack it into a url that a CGI on the server interprets if needed, but it would be best to not require the user to load a special page to submit the data.

If both of these happen to be rather easy, how would they be done?

Thanks! Processing is fun!

1: loadStrings("http://www.yoursite.com/foo/bar.txt");

2: You can use CGI or PHP or whatever and get it with (for instance) loadStrings("http://www.yoursite.com/foo/baz.php?newval="+myNewValueString);

Still lots to be done to both client and server though!
