The IJDb globe applet v2.0
|
|
The globe applet illustrated on the left is used by the IJDb as a tool for illustrating geographic
data. The first version of this applet illustrated the location of juggling clubs on the globe as little red
'pins', however I soon realised that with further modification, this applet could be used to pin-point
a location, and search the database for the clubs (or other items) closest to that point. I have continued
to develop this applet to enable the user to search for all types of information within this site.
This application has a very long history, having started life in the 1960s. For a full account of this applets
history, please look at Tom's Java page, where I found the
Globe applet (and Tom was kind enough to have provided the full source code on his page).

History
The IJDb globe applet has evolved as follows.
Version 2.10:
- Map data updated by Jason Lee Quinn to remove redundant data and improve coastlines.
- An Ant build file has been added to create a JAR archive.
Version 2.00:
- The code has been cleaned up and refactored.
- The land is now filled so that it looks more like solid land!
- The pins on the globe are now collected into classes
Version 1.00: (Changes made to Tom's globe applet)
- Globe rotation and zoom using mouse-clicks
- Double-buffering
- The illustration of geographic data
- A means of passing the current globe position to another page so that geographic location databases can be searched.
Version 0.1:
For the complete applet history, before it was adopted by this site, please refer to the source files.

Other sites using this code
Since I started using this applet on the IJDb a number of other sites have started using it. A number
of people have also developed their own variants of the applet. The following is a brief list of some of the
more interesting uses of the applet:
