3D on the Web - Pure Java Applets
While there is a lot of buzz about the new Java3D API, applets based on pure Java continue to dominate the 3D applet scene. Most users have a copy of Java, but do not have Java3D on their machine and are not willing to take the time to download the very installation files. Given the ongoing disagreemnents between Microsoft and Sun, it appears unlikely that Java3D will ever be included in the Windows distribution CDs. While this all shakes out - there's always Pure Java!

Pure Java Applets

I've read that there are "hundreds" of 3D applets on the web. I guess it depends on what you include in the definition of "3D applets", but by my count there are well under fifty Pure Java, general purpose, 3D object viewing applets available for download and use by webmasters.

With these applets, all you have to do is direct your browser to the URL where the applet is used. As part of displaying the page, your browser will download the Java applet and use it within the HTML page to display the site 3D content. Files required by the applet will also be downloaded automatically - including 3D object files.

Some 3D engines simply read a data file and display the objects found within the file. Other engines are written to display a specific 3D scene and require that the applet be recompiled if the scene changes.

Both applets and data files range very widely in size. Applets and data files can each be as much over 200K bytes in size - large enough only an inquisitive site visitor will take the time to wait for the download. There are alos several solutions whose combined applet-data file sizes are well under 100K.

You'll have to decide what makes sense for your site. If your visitor is from a company with a T3 connection, the file size is not so critical and even a 500K download might be considered acceptable. If your typical visitor is dialing in over a modem, then small file sizes are very critical and a 50K download is considered fairly large.

Another differentiating criteria for Java 3D engines is the way in which the image is created. Some applets require that an image be created on a custom application, then stored on the server for retrieval by site visitors. Other applets create the 3D object files real-time, either by calling a CGI script to create the image or by creating the image with the applet itself. Generally, most applets work by reading a pre-generated file and displaying an image according to the instructions in the 3D object file.

All of the applets listed below are written in pure Java. They do not use the recently released Java3D. Applets in green are not free. Applets in yellow are free. Generally, the best free applets are placed at the top and the best commercial ones are at the bottom - but the placement is not very accurate and the assessment is a subjective one, so please check them out for yourself. Those applets marked "free*" are free only for non-commercial applications and may include an advertising banner in the display.

The rating that I've assigned tries to take into account how useful the code/applets will be to webmasters. Good image quality and small download size are important, as are feature breadth and number of file formats supported. The bad thing about most of the commercial applets is that you are required to use the vendor's file editor to create the image, typically a proprietary or non-standard format. As I learn more about each applet I'm sure I'll move their ratings around. If you have any suggestions or think I've missed the mark, let me know and I'll take a closer look!
