RART, RANDOM ART
Computer Generated Animations

This is the Rart Home page, enjoy the exploration!

General Information about Rart. Rart is a new art form. It uses Java for platform independence and uses the Internet for demonstration and distribution. We call a work of Rart a Rart universe. An Observer of Rart uses a computer screen as a window onto the ever-changing, never-repeating Rart universe. The creator of a Rart universe we call a Rartist.

Rart Gallery - Rart universes, viewable in most browsers.

Principles of Rart - For the interested browser and potential Rartists. 

The Rart System - For persons interested in the Java implementation of Rart - Under revision June 2011

Using Java to Create Random Art

If you cannot see the animation, your browser may not be Java capable or Java enabled. Since it is important that the Rart universes be observable in the most common browsers the universes themselves use Java as defined by JDK 1.1.8. This means that they can be seen in Microsoft Explorer and AOL browsers that support Java as defined in JDK 1.1.4, thereby making the Rart universes viewable by almost anybody. However, if you got here because you did not see the floating logo, please read on!

In the beginning of Java , through 1999, there was a question if the available Java capable browsers were compatible and/or enabled by default. The situation is now quite changed and all main stream browsers are either built Java capable or offer Java by means of a plug in from Sun. They are also mostly enabled by default and even without the option to turn Java off. It is particularly gratifying that AOL browsers since AOL 5.0 have been Java enabled, with no turnoff option.

Internet Explorer 4.0 and later is OK. My new Windows XP with IE 6.0 came with Java enabled and a Java environment claimed to be 1.1.4. However, it also offers an option (Tools >Internet Options . . . > Advanced) to turn on a Java plug in from Sun, if you have it (One of the crucial items in the Microsoft antitrust court case, was if MS should be required to distribute the Java plug in from Sun and if they did, should it be enabled by default.) Unfortunately the Sun plug in breaks some older applets including the one I had as a banner on this website for a very long time, but it is OK with the present banner.

Netscape Navigator 4.5 is OK and does not seem to have a turnoff option. While Navigator 6 + was dangerously unstable, Netscape 7.0 seems OK. It offers the option under Edit > Preferences > Advanced to disable/enable Java 2. Enabling the optionally downloaded plug in from Sun, breaks old applets just as for Explorer.

The story is the same for Macintosh, Mac OS 9.0 as well as OS X. All main browsers work and are normally enabled. However, older Macintoshes don't handle xor painting correctly, which brakes the Eggs universe. The Lines and the Polygons also look funny on my G4 Laptop under OS X 1.2. I was extremely pleased to note, however, that the new browser that comes with OS X 1.4, Tiger, the Safari, has a beautiful and fast Java engine. While it can be disabled (under Preferences), it is normally enabled and, again, really, really nice!

For Linux/Unix, I have also checked Opera, which comes with an optional Java plug in from Sun. My RedHat Linux came with Galeon using a Sun plug in (1.3.1_02) and Netscape 4.78 using Java 1.1.5. which all are good for observing Rart universes.

As of now, 2010, matters seem to have stabilized. Most browsers,  Firefox, Mozilla, Crome from Google, AOL etc. come with Java enabled and are expected to use a Java plug in from Sun, Sun has recently been taken over by Oracle but Oracle has pledged continued support for Java of which Oracle has been a heavy user anyway. Microsoft is supporting Java in the same way, but is posting two levels of warning messages in Internet Explorer 8.0.
