Running processing applications within Quartz
Mar 19^th, 2009, 12:43pm

Hi,

Our third-year students in comp sci at Queen Mary, University of London have just submitted their Interaction Design project, under the form of a Processing application. Some of these are really nice and we want to have 10 of these applications on display on the plasma screens we have throughout the department. These screens are managed by a Mac, and the display is controlled by Quartz. I was wondering whether it was possible to load the programs within Quartz in sequence, so that each of them would run for e.g. 10 minutes.

Does anyone know if that's possible? I suppose that it could be possible also to combine all the codes into one big application that would control which app to play, but that would be a lot easier if Quartz was able to deal with each program independantly.

Thanks,
Jean-Baptiste

I thought that Quartz was the Apple's display system, a bit like QuickTime. I don't see how it can sequence applications. Perhaps it can do more than I know.

Anyway, if you don't have a better method, you can have a look at my answer Re: Sequencing, display update, and functions.
It shows how I transformed two (simple) sketches to run them sequentially for a given amount of time.
Not sure if it can help you, but maybe it can give ideas.

Hi!

OSx has an application called Quartz Composer, it utilises patches to create some amazing stuff.

One of the patches accepts java code. I would personally like to be able to paste in the converted (end result) java into here to be able to run processing within a Quarts app, though I don't think it can run all Java code (for security reasons I think)...

Anyway, I think this is what the op was about.

Aaah, thanks. That's the problem of truncating application name (like lot of people saying Outlook for Outlook Express, a very different beast).

Note that you can export your sketch, it will output a .jar file. Either you can use that in Quartz Composer, or you can open it (like a .zip file) to get the .class files.
You can even get the generated .java files in the temp dir of your system...

Hi,

Just to let you know, we have solved the problem of displaying several applets in random turns. We haven't used Quartz at all in the end, but loaded the applets in Safari and reload the page every 30 seconds. There was some problems with the memory allocation but after a bit of tweaking it worked quite well. Some 10 applets now take turn and are on display.

I can post the html code here if anyone is interested.

best,
Jean-Baptiste

Here is the code for the page (includes php and html)

<?php

$applets = array('info1' => array ( 'archive' => 'applet1.jar',
'classid' => 'applet1.class',
'author'=> 'Author2',
'title' => 'Demonstration 1),
'info2' => array ( 'archive' => 'applet2.jar' ,
'classid' => 'applet2.class',
'author'=>'Author2',
'title' => 'Demonstration 2'),
'info3' => array ( 'archive' => 'applet3.jar' ,
'classid' => 'applet3.class',
'author'=>'Author3',
'title' => 'Demonstration 3'));

$keys = array_keys($applets);
$nth = array_rand($keys, 1);
$key = $keys[$nth];
$mychoice = $applets[$key];
$archive = 'applets/' . $key . '/' . $mychoice['archive'];
$archive = preg_replace('/\,/',",applets/$key/",$archive);
$classid = 'java:' . $mychoice['classid'];
?>
